# Grails Guides: Publishing Architecture and Migration Plan
This document describes how Grails guide publishing works today, what's wrong with
it, and the plan to consolidate everything into `apache/grails-static-website`.

## Current Architecture Overview
Guide publishing spans **three layers**:
1. **94 individual guide repos** in the `grails-guides` GitHub org (e.g.
`grails-guides/creating-your-first-grails-app`) -- each is a standalone Grails
project containing AsciiDoc source, an `initial/` starter project, and a
`complete/` solution.
2. **`grails-guides/grails-guides-template`** (infrastructure + deployment repo) --
provides the shared build plugin (`gradle/guide-build.gradle`), guide scaffolding
script (`create-guide.sh`), CI/CD scripts (`githubactions/`), common AsciiDoc
snippets (`src/main/docs/`), and theme resources (`src/main/resources/`).
Its **`gh-pages` branch** stores the built HTML for every guide, the central
`guides.json` registry, and the guides index site served at
`https://guides.grails.org`.
3. **`apache/grails-static-website`** (this repo) -- generates the guides *index site*
(listing, search, tag/category pages) by fetching `guides.json` at build time.
The output is pushed back to `grails-guides/grails-guides-template` `gh-pages`.
> **Note**: Many CI scripts and individual guide `build.gradle` files still reference
> the old URL `grails/grails-guides`. This was the former location of
> `grails-guides/grails-guides-template` before it was moved to the `grails-guides`
> GitHub org. GitHub redirects mask this, but the references are stale.
### The `grails-guides` GitHub Org
The `grails-guides` GitHub org contains **95 repositories**:
- **`grails-guides-template`** -- the infrastructure repo described above.
- **94 individual guide repositories** -- each named after the guide topic.
Every individual guide repo in the org:
- Has its own GitHub Actions CI workflow (manually set up -- not generated by the
scaffolding script)
- May maintain version branches (`master`, `grails3`, `grails4`, `grails5`, `grails6`)
- Applies `guide-build.gradle` remotely from `grails-guides-template` at Gradle build time
- Downloads and executes CI scripts from `grails-guides-template` at CI runtime via `curl`
- Pushes built HTML and metadata to `grails-guides-template` `gh-pages`

## Complete Repo Inventory
### Repos with both `initial/` and `complete/` directories (79)
These repos contain runnable sample Grails applications. After migration, these
repos will **remain in the `grails-guides` org** as sample project repos (with
doc-publishing stripped out). AsciiDoc source moves to `grails-static-website`.

### Repos with `complete/` only -- no `initial/` (14)
These repos have a completed sample project but no starter project. The 7
quickcast repos are video-companion code (no interactive tutorial flow). After
migration, repos with meaningful sample code remain in the org; doc-only repos
(quickcasts) can be archived entirely.
| Repo | Published | Repo branches | Notes |
|------|-----------|---------------|-------|
| `gorm-without-grails` | Yes (master) | grails3, master | Standalone GORM demo |

| `using-the-react-profile` | Yes (master) | master | |
| `using-the-vue-profile` | Yes (master, grails3) | dependabot branch, grails3, master | |
### Repos with neither `initial/` nor `complete/` (1)
| Repo | Published | Repo branches | Notes |
|------|-----------|---------------|-------|
| `grails-acl` | **No** | master | Doc-only, never published |
### Repos in org but NOT published in `guides.json` (10)
These repos exist in the `grails-guides` org but have no corresponding entry in
`guides.json`, meaning they do not appear on `https://guides.grails.org`. Their
CI may never have successfully run `updateGuidesJson`, or they may be incomplete.
| Repo | `initial/` | `complete/` | Branches |
|------|------------|-------------|----------|
| `grails_api_ai` | yes | yes | master |
| `grails-acl` | no | no | master |
| `grails-android-security` | yes | yes | master, upgrade |
| `grails-deploy-aws-elastic-beanstalk` | yes | yes | master |
| `grails-deploy-heroku` | yes | yes | master |
| `grails-deploy-pws` | yes | yes | grails5, grails-4, master |
| `grails-ios-objectivec-security` | yes | yes | master, upgrade |
| `grails-oauth-facebook` | yes | yes | master |
| `react-router-spring-security` | yes | yes | master |
| `web-app-step-by-step` | yes | yes | compilestatic, link-to-grails-download, master, sdkman-link, sett, sett-rev |
### Known data issues
- **Typo in `guides.json`**: `grails-micronaut-kakfa` should be `grails-micronaut-kafka`
- **Category case inconsistency**: `guides.json` has both `"Grails + DevOps"` (6 guides)
and `"Grails + Devops"` (1 guide) -- should be unified
- **Branch value issue**: `grails-on-travis-basics` has a `guides.json` entry with
`githubBranch` set to `"master,grails3"` (comma inside the value) instead of being
two separate entries
- **Underscored repo names**: `grails_api_ai`, `grails_i18n`, `grails_url_mappings`
use underscores instead of hyphens (inconsistent with all other repo names)
---
## Grails Version Analysis
### Branch distribution across repos
Repos use version branches to maintain guides for different Grails versions. The
branch naming is inconsistent -- some use `grails4`, others use `grails-4`:
| Branch | Repos | Notes |
|--------|-------|-------|
| `master` | 93 | Present in almost every repo; maps to Grails 4 in `guides.json` |
| `grails3` | 40 | Grails 3.x version |
| `grails-4` | 25 | Grails 4.x version (hyphenated variant) |
| `grails4` | 2 | Grails 4.x version (non-hyphenated variant) |
| `grails5` | 37 | Grails 5.x version |
| `grails6` | 3 | Grails 6.x version |
**Only 3 repos have been updated to Grails 6**: `grails-configuration-properties-micronaut`,
`grails-database-migration`, and `grails-micronaut-http`.
### Published versions in `guides.json`
The `guides.json` branch-to-major-version mapping (in `GuidesFetcher.groovy`):
```groovy
BRANCH_TO_MAJOR = [grails3: 3, grails4: 4, master: 4, grails5: 5, grails6: 6]
```
This means `master` = Grails 4 in the published guides. The mapping does NOT
include `grails-4` (hyphenated), so repos with a `grails-4` branch but no
`grails4` branch are effectively not publishing a separate Grails 4 version --
their `master` branch serves as the Grails 4 version.
Of the 40 multi-version guides in `guides.json`:
- **37** have exactly `master` + `grails3` (Grails 4 + Grails 3)
- **1** has `grails4` + `grails6` (`grails-configuration-properties-micronaut`)
- **1** has `grails4` + `grails3` + `grails6` (`grails-database-migration`)
- **1** has a data issue (`grails-on-travis-basics` -- comma-separated in one entry)
### What "multi-version" really means today
In practice, almost all multi-version guides are just Grails 3 vs Grails 4 (`master`).
Despite 37 repos having a `grails5` branch and 25 having a `grails-4` branch, these
branches have NOT been published to `guides.json` because:
1. The `githubactions-build.sh` template curls `build-guide` from
`grails-guides-template` **`master`** branch
2. The `master` branch version of `build-guide` only handles `master` and `grails3`
branches for publishing
3. The `6.0.x` branch version handles `grails3`-`grails6` but is not used by any
guide repo's CI
This means the `grails5` branches in 37 repos and `grails-4` branches in 25 repos
exist in Git but their built docs were **never published**.
### Unpublished branch analysis
The `grails5` and `grails-4` branches were never published to `guides.json` (see
above), but many contain distinct content that should be considered for publishing
during migration. The table below shows each branch's relationship to `master`.
**`grails5` branches (37 repos)**:
| Status | Count | Meaning |
|--------|-------|---------|
| Ahead of master | 35 | Branch has unique commits not in master -- **distinct content** |
| Behind master | 2 | Branch is a subset of master -- no unique content |
| Repo | Ahead | Behind | Status | Commit summary | File-level changes |

## How Publishing Works Today
This is the end-to-end lifecycle of a guide in the current system, from creation
to appearing on `https://guides.grails.org`:
### Step 1: Scaffold the guide
An author clones `grails-guides-template` and runs `create-guide.sh`:
```bash
./create-guide.sh my-new-guide
```
This script:
1. Runs `grails create-app my-new-guide` to generate a Grails app
2. Renames the app directory to `initial/`
3. Copies `initial/` to `complete/`
4. Writes `settings.gradle` with `include 'complete', 'initial'`
5. Copies template files from `src/main/project/` into the guide root
The template files copied are:
- `build.gradle` -- applies `guide-build.gradle` remotely
- `gradle.properties` -- metadata stub with `TODO` placeholders
- `githubactions-build.sh` -- CI entrypoint (curls scripts at runtime)
- `src/main/docs/guide/` -- AsciiDoc skeleton (`toc.yml`, `gettingStarted.adoc`, etc.)
**What is NOT created by the script:**
- `.github/workflows/` -- the GitHub Actions workflow YAML must be created manually
- No CI configuration is auto-generated
### Step 2: Create the GitHub repo
The author manually:
1. Creates a new repository in the `grails-guides` org on GitHub
2. The repo name must match the guide directory name
3. Pushes the scaffolded project
### Step 3: Set up CI manually
The author must manually:
1. Create `.github/workflows/gradle.yml` (or similar) -- there is no template for this
2. Configure repository secrets: `GH_TOKEN`, `GIT_NAME`, `GIT_EMAIL`
A typical workflow looks like this (from `creating-your-first-grails-app`):
```yaml
name: Java CI with Gradle
on:
push:
branches: [ master ]
pull_request:
branches: [ master ]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Set up JDK 11
uses: actions/setup-java@v2
with:
java-version: '11'
distribution: 'adopt'
cache: gradle
- name: Run script
run: ./githubactions-build.sh
env:
GH_TOKEN: ${{ secrets.GH_TOKEN }}
GIT_NAME: ${{ secrets.GIT_NAME }}
GIT_EMAIL: ${{ secrets.GIT_EMAIL }}
```
Note: many of these workflows are outdated (actions/checkout@v2, JDK 11, adopt
distribution). The `grails-guides-template` README still references Travis CI as
the CI system, with instructions for `travis encrypt` -- GitHub Actions was
retrofitted without updating the docs.
### Step 4: CI runs and the guide gets published
On push, the workflow runs `./githubactions-build.sh`. This is where it gets wild:
#### 4a. `githubactions-build.sh` (in the guide repo)
This script does **not** contain any build logic. It downloads and executes scripts
from `grails-guides-template` at runtime via `curl`:
```bash
#!/bin/bash
set -e
export EXIT_STATUS=0
# Download the build script from grails-guides-template master branch at runtime
curl -O https://raw.githubusercontent.com/grails/grails-guides/master/githubactions/build-guide
chmod 777 build-guide
./build-guide || EXIT_STATUS=$?
if [[ $EXIT_STATUS -ne 0 ]]; then
echo "build-guide failed"
exit $EXIT_STATUS
fi
# Download the republish script from grails-guides-template master branch at runtime
curl -O https://raw.githubusercontent.com/grails/grails-guides/master/githubactions/republish-guides-website.sh
chmod 777 republish-guides-website.sh
./republish-guides-website.sh || EXIT_STATUS=$?
exit $EXIT_STATUS
```
Every single guide repo has an identical copy of this file. All 94 of them `curl`
the same two scripts from `grails-guides-template` `master` branch (using the old
`grails/grails-guides` URL).
#### 4b. `build-guide` (curled from `grails-guides-template`)
This is the actual build logic. It:
1. Runs `./gradlew -Dgeb.env=chromeHeadless check` (tests)
2. Runs `./gradlew publishGuide` (AsciiDoc -> HTML)
3. **Only for specific branches** (`master`, `grails3`, `grails4`, `grails5`, `grails6`):
- Clones `grails-guides-template` `gh-pages` branch
- Runs `./gradlew updateGuidesJson` -- **this is how a guide gets added to
`guides.json`** (the central registry). The task reads `gradle.properties` and
upserts the guide's metadata into the JSON file.
- Copies built HTML to the appropriate directory on `gh-pages`:
- `master` branch -> `<guide-name>/` (root, no version prefix)
- `grails3` branch -> `grails3/<guide-name>/`
- `grails4` branch -> `grails4/<guide-name>/`
- etc.
- Commits and pushes to `gh-pages`
**Branch discrepancy**: The `master` branch of `grails-guides-template` has a
`build-guide` that only handles `master` and `grails3`. The `6.0.x` branch version
handles `grails3`, `grails4`, `grails5`, `grails6` (not `master`). Since the
`githubactions-build.sh` template curls from `master`, guides using that template
only get the older behavior.
#### 4c. `republish-guides-website.sh` (curled from `grails-guides-template`)
After the guide is built, this script **regenerates the entire guides index site**:
1. Clones `grails/grails-static-website` (this repo, using old URL) `master` branch
2. Runs `./gradlew buildGuide` -- which fetches `guides.json` from `gh-pages` and
generates index/tag/category HTML pages
3. Clones `grails-guides-template` `gh-pages` again
4. Copies `build/dist/*` (the generated index pages) into `gh-pages`
5. Commits and pushes
This means **every single guide CI build triggers a full rebuild of the entire guides
index site**. And the same rebuild also runs every 2 hours via the cron job in
`grails-static-website`'s `publish.yml`.
### Step 5: The guide appears on `guides.grails.org`
Once the `gh-pages` push completes, the guide is live:
- Guide HTML: `https://guides.grails.org/<guide-name>/guide/index.html`
- Versioned: `https://guides.grails.org/grails{N}/<guide-name>/guide/index.html`
- Listed on the index: `https://guides.grails.org/index.html`
- Searchable by tags and categories
The guide was added to `guides.json` by `updateGuidesJson` (step 4b) and the index
was regenerated by `republish-guides-website.sh` (step 4c), so it shows up in the
listing immediately.

Additionally, `grails-static-website`'s own `publish.yml` runs the same

- On every push to `master`
- On a cron schedule every 2 hours
- On manual `workflow_dispatch`

### Guide `build.gradle`
Every guide's `build.gradle` remotely applies the shared build script. Some reference
`master`, some `6.0.x`:
```groovy
plugins {
id 'org.asciidoctor.convert' version '1.5.3'
}
asciidoctorj {
version = '1.5.4'
}
// NOTE: old URL; actual repo is grails-guides/grails-guides-template
apply from:"https://raw.githubusercontent.com/grails/grails-guides/master/gradle/guide-build.gradle"
```
### Guide `gradle.properties`
```properties
title=Creating your first Grails Application
subtitle=Learn how to create your first Grails app
authors=Zachary Klein
copyright=Copies of this document may be made for your own use and for...
githubSlug=grails-guides/creating-your-first-grails-app
githubBranch=master
category=Grails Apprentice
tags=mysql,gsp,grails4
publicationDate=23 Jan 2017
```
| Property | Description | Required |
|-------------------|--------------------------------------|----------|
| `title` | Display title | Yes |
| `subtitle` | Short description | Yes |
| `authors` | Comma-separated authors | Yes |
| `githubSlug` | Repo identifier (`grails-guides/...`)| Yes |
| `githubBranch` | Git branch | Yes |
| `tags` | Comma-separated tags | Yes |
| `category` | Must match a predefined category | Yes |
| `publicationDate` | Format: `dd MMM yyyy` | Yes |
### Shared build plugin: `guide-build.gradle`
Applied remotely by every guide. Key tasks:
- **`prepareResources`** -- downloads `grails-guides-template` (branch `6.0.x`) as
a ZIP from GitHub and extracts theme resources (CSS, fonts, images) and common
AsciiDoc snippets. This is a network fetch on every build.
- **`copyLocalGuideImgResources`** -- copies guide-specific images from
`src/main/resources/img/` into the extracted build tree.
- **`publishGuide`** -- runs `grails.doc.gradle.PublishGuide` (from
`org.grails:grails-docs:6.0.0-RC1`) to convert AsciiDoc to HTML.
Output: `build/docs/guide/single.html` renamed to `build/docs/guide/index.html`.
Also creates a redirect `build/docs/index.html`.
- **`updateGuidesJson`** -- reads `gh-pages/guides.json`, upserts the current guide's
metadata from `gradle.properties`, writes the updated JSON back. This is how a
guide registers itself in the central metadata file.
Validation at task graph resolution time enforces that all required properties are
set and not `TODO`.
### Guides index generation (this repo: `grails-static-website`)
The `buildGuides` Gradle task (registered in `GrailsWebsitePlugin`) orchestrates:
```
buildGuides
├── genGuides (GuidesTask) -- fetches guides.json, generates HTML pages
├── copyAssets (AssetsTask) -- copies CSS/JS/images
└── genSitemap (SitemapTask) -- generates sitemap.xml
```
**`GuidesFetcher`** (`buildSrc/.../model/guides/GuidesFetcher.groovy`):
- Fetches `guides.json` from
`https://raw.githubusercontent.com/grails-guides/grails-guides-template/gh-pages/guides.json`
- Parses each entry into a `GuideDto`
- Groups by `githubSlug`; creates `SingleGuide` (one branch) or
`GrailsVersionedGuide` (multiple branches like grails3/4/5/6)
- Branch-to-version mapping: `grails3`->3, `grails4`->4, `master`->4, `grails5`->5, `grails6`->6
- Filters out future-dated guides, sorts newest-first
**`GuidesTask`** (`buildSrc/.../tasks/GuidesTask.groovy`):
- Calls `GuidesFetcher.fetchGuides()` and `TagUtils.populateTags(guides)`
- Generates `build/temp/guides.html` (main listing)
- Generates `build/temp/tags/<tag>.html` for each tag
- Generates `build/temp/categories/<category>.html` for each category
- Renders all through the site template into `build/dist/`
**`GuidesPage`** (`buildSrc/.../model/guides/GuidesPage.groovy`):
- Renders HTML using Groovy `MarkupBuilder`
- 14 predefined categories with SVG icons
- Links to `https://guides.grails.org/<name>/guide/index.html` (single)
- Links to `https://guides.grails.org/grails{N}/<slug>/guide/index.html` (versioned)
- Features: latest guides list (8 most recent), tag cloud, search box, category grouping
### Main site publishing (`publish.yml` workflow)
The GitHub Actions workflow runs on push to master, every 2 hours via cron, and on
manual dispatch:
```yaml
# Step 1: Build and publish the main grails.apache.org site
GRADLE_TASK: build
GITHUB_SLUG: apache/grails-website
GH_BRANCH: asf-site-production
# Step 2: Build and publish the guides.grails.org index site
GRADLE_TASK: buildGuide
GITHUB_SLUG: grails-guides/grails-guides-template
GH_BRANCH: gh-pages
```
Both steps use `publish.sh`, which runs the Gradle task, clones the target repo's
deploy branch, copies `build/dist/` into it, and pushes.
---
## Current Pain Points
1. **Runtime `curl` of CI scripts** -- every guide CI run downloads `build-guide`
and `republish-guides-website.sh` from GitHub at runtime. The CI logic is not
committed to the guide repos; it's fetched live. This is fragile (GitHub outage
= broken CI) and opaque (the actual CI behavior is invisible in the guide repo).
2. **Remote `apply from` for Gradle builds** -- every guide's `build.gradle` fetches
`guide-build.gradle` from GitHub at Gradle configuration time. Combined with
`prepareResources` downloading a ZIP of `grails-guides-template`, a single guide
build makes 3+ HTTP requests to GitHub before any real work begins.
3. **Cascading index rebuilds** -- every single guide CI build runs
`republish-guides-website.sh`, which clones this entire repo, runs
`./gradlew buildGuide`, and pushes the result. If 5 guides push in the same hour,
the index gets rebuilt 5 times -- plus once more from the cron job. These can also
race and cause push conflicts on `gh-pages`.
4. **Stale old-URL references everywhere** -- the `githubactions-build.sh` in all 94
guide repos curls from `grails/grails-guides` (old URL). The `build-guide` and
`republish-guides-website.sh` scripts clone `grails/grails-guides` (old URL) and
`grails/grails-static-website` (old URL). Guide `build.gradle` files apply from
`grails/grails-guides` (old URL). GitHub redirects mask this but add fragility.
5. **`master` vs `6.0.x` branch discrepancy in `build-guide`** -- the `master`
branch version of `build-guide` only handles `master` and `grails3` branches.
The `6.0.x` branch version handles `grails3`-`grails6` (not `master`). Since
the curled template references `master`, guides using the default template only
publish for `master` and `grails3`. This is why only 3 guides have published
Grails 6 content despite 3 repos having a `grails6` branch, and why 37 repos
with `grails5` branches have never published Grails 5 content.
6. **No workflow template in scaffolding** -- `create-guide.sh` copies
`build.gradle`, `gradle.properties`, `githubactions-build.sh`, and docs, but does
NOT create `.github/workflows/`. The GitHub Actions workflow must be created and
configured manually for each guide, leading to inconsistency across 94 repos.
7. **Outdated README** -- the `grails-guides-template` README documents Travis CI
as the CI system (with `travis encrypt` instructions). GitHub Actions was
retrofitted without updating the documentation.
8. **Outdated guide workflows** -- many guide repos use `actions/checkout@v2`,
`actions/setup-java@v2`, JDK 11, and `adopt` distribution. These are years out
of date.
9. **Overloaded `gh-pages` branch** -- `grails-guides-template` `gh-pages` stores
built guide HTML (pushed by 94 individual guide CIs), `guides.json` (mutated by
`updateGuidesJson` from each guide CI), AND the index site (pushed by both
`republish-guides-website.sh` and `grails-static-website`'s cron). Multiple
independent CI pipelines write to the same branch concurrently.
10. **`guides.json` as the integration point** -- metadata is serialized to JSON in
one repo, fetched via HTTP in another. Changes to the schema require coordinating
across repos.
11. **Stale `grails-docs` dependency** -- the `PublishGuide` task comes from
`org.grails:grails-docs:6.0.0-RC1`, a Grails-specific doc toolchain. Modern
AsciiDoctor Gradle plugins are more capable and actively maintained.
12. **94 repos to maintain** -- the `grails-guides` org has 94 individual guide repos
plus the template. Most target older Grails versions (only 3 have Grails 6
branches). Maintaining permissions, branch policies, and secrets across all of
them is significant overhead.
13. **10 unpublished repos** -- 10 repos exist in the org but never made it into
`guides.json`, so they are invisible on the guides site. Their status is unclear.
14. **Inconsistent branch naming** -- 25 repos use `grails-4` (hyphenated) while 2
use `grails4` (unhyphenated). The `GuidesFetcher` branch mapping only recognizes
`grails4`, meaning the 25 repos with `grails-4` branches are not properly mapped.

# Part 2 -- Migration Plan
## Consolidation Plan
### Goal
Move all guide AsciiDoc source and publishing infrastructure into
`grails-static-website` so that:
- All guide AsciiDoc source lives in this repo
- Guide metadata is defined in a single YAML file (`conf/guides.yml`)
- Built guide HTML and the index site are deployed together
- One CI pipeline handles everything
- No runtime `curl` of scripts, no remote `apply from`, no cascading rebuilds
- The `grails-guides` GitHub org retains only repos with `initial/`+`complete/`
sample applications (79 repos), serving purely as runnable code companions
### Phase 1: Move guide metadata here
**What**: Create `conf/guides.yml` in this repo containing all guide metadata
currently in `guides.json`. Stop fetching from GitHub at build time.
**Changes**:
- Add `conf/guides.yml` with all 84 published guide entries (title, authors, tags,
category, publication date, Grails versions)
- Fix the `grails-micronaut-kakfa` typo to `grails-micronaut-kafka`
- Unify `"Grails + DevOps"` / `"Grails + Devops"` category case
- Add entries for the 10 currently unpublished repos (or explicitly exclude them)
- Add a `guides` property to `GrailsWebsiteExtension` pointing to it
- Modify `GuidesFetcher` to read from a local YAML file instead of a remote JSON URL
- Update `GuidesTask` to accept the local file as an `@InputFile`
**Benefits**: No more network dependency during builds. Metadata changes are
version-controlled with the site. Adding/updating a guide is a simple YAML edit + PR.
**Impact on `grails-guides` org**: None yet. Individual guide repos continue to
function as before; their CI just becomes the non-authoritative source for metadata.
### Phase 2: Move common doc snippets and theme resources here
**What**: Bring `src/main/docs/common-*.adoc` (~45 files) and `src/main/resources/`
(CSS, fonts, images) from `grails-guides-template` into this repo.
**Changes**:
- Copy `grails-guides-template/src/main/docs/common-*.adoc` to `guides/common/`
- Copy `grails-guides-template/src/main/resources/` to `guides/resources/`
- Update `guide-build.gradle` (or its replacement) to reference local paths
- Individual guide repos can still exist but would reference resources from this repo
**Benefits**: Theme and common content are versioned with the site. No ZIP download
at build time (`prepareResources` task eliminated).
**Impact on `grails-guides-template`**: Its source branches (`master`, `6.0.x`) become
redundant for `src/main/docs/` and `src/main/resources/`. Only `gh-pages` is still
needed until Phase 5.
### Phase 3: Move `guide-build.gradle` here
**What**: Bring the shared Gradle build plugin into `buildSrc/` alongside the existing
site build logic.
**Changes**:
- Port `guide-build.gradle` tasks (`publishGuide`, `updateGuidesJson`) into
`buildSrc/` as proper Gradle task classes (like `GuidesTask` already is)
- Replace the `org.grails:grails-docs` `PublishGuide` dependency with the standard
`org.asciidoctor.jvm.convert` Gradle plugin
- Individual guide repos would `apply from` this repo (or use a published plugin)
**Benefits**: Build logic is testable, type-safe Groovy/Java classes. Modern
AsciiDoctor tooling. Single place to update build conventions.
**Impact on `grails-guides-template`**: `gradle/guide-build.gradle`,
`create-guide.sh`, and `githubactions/` become dead code. The repo's source branches
are now fully superseded.
**Impact on individual guide repos**: Their `build.gradle` must be updated to point
the `apply from` URL at this repo (or use a published Gradle plugin). This can be
done incrementally per guide.
### Phase 4: Move ALL guide AsciiDoc source here
**What**: Move the AsciiDoc source from every guide repo into this repo. This is
**mandatory** for all 84 published guides and optionally for the 10 unpublished ones.
**Changes**:
- Create `guides/<guide-name>/` directories containing `guide/toc.yml` and `.adoc` files
- Add a Gradle task to build all local guides in one pass
- The `buildGuides` task builds all guide HTML from local AsciiDoc source
- `conf/guides.yml` references the local path for each guide
**Per-guide migration procedure**:
1. **Copy AsciiDoc**: Copy `src/main/docs/guide/` from the guide repo into
`guides/<guide-name>/` in this repo
2. **Copy guide-specific images**: Copy `src/main/resources/img/` into
`guides/<guide-name>/images/`
3. **Update `conf/guides.yml`**: Ensure the guide entry has `source: local`
4. **Remove doc-publishing from the guide repo**: Delete `src/main/docs/`,
`githubactions-build.sh`, the doc-related parts of `build.gradle`, and
`gradle.properties` metadata fields used only for doc publishing
5. **Update the guide repo CI**: If the repo has `initial/`+`complete/` sample
projects, keep a simplified workflow that only builds/tests the sample apps
(no more `publishGuide`, `updateGuidesJson`, or `republish-guides-website.sh`).
If the repo has no sample projects, archive it entirely.
**What happens to each repo category**:
| Category | Count | Action |
|----------|-------|--------|
| Has both `initial/` and `complete/` | 79 | AsciiDoc moves here. Repo keeps sample projects with simplified CI. |
| Has `complete/` only (non-quickcast) | 7 | AsciiDoc moves here. Strip doc-publishing, archive the repo. |
| Has `complete/` only (quickcast) | 7 | AsciiDoc moves here. Strip doc-publishing, archive the repo. |
| Has neither dir | 1 | `grails-acl` -- doc-only, never published. Archive the repo. |
| Unpublished (in org, not in `guides.json`) | 10 | Evaluate each: migrate AsciiDoc if the guide has value; archive if abandoned. |
**Proposed structure**:
```
grails-static-website/
├── conf/
│ └── guides.yml <-- all guide metadata (84+ entries)
├── guides/
│ ├── common/ <-- shared AsciiDoc snippets (from grails-guides-template)
│ ├── resources/ <-- theme CSS, fonts, images (from grails-guides-template)
│ ├── creating-your-first-grails-app/
│ │ ├── toc.yml
│ │ ├── images/ <-- guide-specific images
│ │ └── guide/*.adoc
│ ├── grails-mock-basics/
│ │ ├── toc.yml
│ │ └── guide/*.adoc
│ └── ... (84+ guide directories)
├── buildSrc/
│ └── .../guides/
│ ├── GuidesFetcher.groovy <-- reads conf/guides.yml
│ ├── GuidesTask.groovy <-- generates index site
│ ├── GuideBuildTask.groovy <-- NEW: builds individual guide HTML
│ └── ...
└── .github/workflows/
└── publish.yml <-- single workflow for site + guides
```
### Phase 5: Simplify deployment
**What**: Deploy everything (main site + guide HTML + guide index) as part of
`grails.apache.org`. All guides will be served at `https://grails.apache.org/guides/`.
**Changes**:
- Build output produces one unified `build/dist/` tree:
```
build/dist/
├── index.html <-- grails.apache.org homepage
├── guides/
│ ├── index.html <-- grails.apache.org/guides/ listing
│ ├── categories/*.html
│ ├── tags/*.html
│ └── <guide-name>/
│ └── guide/index.html <-- individual guide HTML
└── ...
```
- A single `publish.yml` step pushes to `apache/grails-website` `asf-site-production`
- Remove the second `publish.sh` step that pushes to `grails-guides-template` `gh-pages`
- Eliminate `republish-guides-website.sh` -- no more cascading rebuilds
- Update `GUIDES_URL` in `GuidesPage.groovy` from `https://guides.grails.org` to
`https://grails.apache.org/guides`
**New URL structure**:
- `https://grails.apache.org/guides/` -- guides listing (index)
- `https://grails.apache.org/guides/<guide-name>/guide/index.html` -- individual guide
- `https://grails.apache.org/guides/tags/<tag>.html` -- guides by tag
- `https://grails.apache.org/guides/categories/<category>.html` -- guides by category
**Benefits**: One deploy, one repo, one domain. No cross-repo push
choreography. No concurrent writes to `gh-pages`. Drastically simpler CI/CD.
### Phase 6: Strip doc-publishing from guide repos
**What**: After AsciiDoc source has been migrated (Phase 4), strip the doc-publishing
machinery from every guide repo in the `grails-guides` org.
**Per-repo procedure for repos keeping `initial/`+`complete/` (79 repos)**:
1. Delete `src/main/docs/` (AsciiDoc source -- now in `grails-static-website`)
2. Delete `githubactions-build.sh` (no longer needed)
3. Simplify `build.gradle`:
- Remove the `apply from:` that fetches `guide-build.gradle`
- Remove the `asciidoctor` plugin
- Keep only what's needed to build/test `initial/` and `complete/` subprojects
4. Remove doc-publishing metadata from `gradle.properties` (title, subtitle, authors,
githubSlug, githubBranch, category, tags, publicationDate)
5. Update `.github/workflows/gradle.yml`:
- Remove the `./githubactions-build.sh` step
- Replace with `./gradlew check` to just run tests on the sample apps
- Update to modern actions versions (checkout@v4, setup-java@v4, JDK 17+)
- Remove `GH_TOKEN` / `GIT_NAME` / `GIT_EMAIL` secrets (no longer pushing to gh-pages)
6. Add a `README.md` note: "Guide content is published from
[apache/grails-static-website](https://github.com/apache/grails-static-website).
This repo contains only the sample applications."
**For repos with `complete/` only (14 repos)**:
Same stripping procedure as above, then archive the repo. These repos have no
`initial/` project, so they do not serve as interactive tutorial companions.
The `complete/` code is preserved in the archived repo for reference.
**For repos with neither dir (1 repo: `grails-acl`)**:
Archive the repo. It was never published and has no sample code.
### Phase 7: Wind down `grails-guides-template`
**What**: After consolidation is complete, clean up `grails-guides-template`.
**Impact on `grails-guides/grails-guides-template`**:
- Source branches (`master`, `6.0.x`) are fully superseded after Phases 2-3 --
all build logic, common docs, and theme resources now live in `grails-static-website`
- `gh-pages` branch continues to serve `guides.grails.org` via GitHub Pages, but
all HTML files are replaced with meta-refresh redirects to `grails.apache.org/guides/`
(see URL Redirect Plan below)
- **Action**: Replace all HTML on `gh-pages` with redirect stubs. Archive the repo's
source branches. The `gh-pages` branch stays live to serve redirects indefinitely.
**Impact on the `grails-guides` org after all phases**:
| What remains | Count | Purpose |
|-------------|-------|---------|
| Repos with `initial/`+`complete/` sample apps | 79 | Runnable code companions for guides (no doc-publishing) |
| Repos archived (`complete/`-only, doc-only, obsolete) | 15 | Read-only reference (14 complete-only + 1 no-code) |
| `grails-guides-template` | 1 | Source branches archived; `gh-pages` stays live for redirects |
### URL Redirect Plan
Current guide URLs follow the pattern:
```
https://guides.grails.org/<guide-name>/guide/index.html (single version)
https://guides.grails.org/grails{N}/<guide-name>/guide/index.html (versioned)
```
After consolidation, guides will be served from `grails.apache.org/guides/`. To
preserve existing links, the `grails-guides-template` `gh-pages` branch (which
serves `guides.grails.org` via GitHub Pages) will be updated with meta-refresh
redirects pointing to the new `grails.apache.org` URLs.
**Redirect implementation**: Replace all HTML files on `gh-pages` with redirect
stubs using `<meta http-equiv="refresh">`:
```html
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="0; url=https://grails.apache.org/guides/<guide-name>/guide/index.html">
<link rel="canonical" href="https://grails.apache.org/guides/<guide-name>/guide/index.html">
</head>
<body>
<p>This page has moved to
<a href="https://grails.apache.org/guides/<guide-name>/guide/index.html">
grails.apache.org/guides/<guide-name>/guide/index.html
</a>.
</p>
</body>
</html>
```
This covers:
- `https://guides.grails.org/<guide-name>/guide/index.html` ->
`https://grails.apache.org/guides/<guide-name>/guide/index.html`
- `https://guides.grails.org/grails{N}/<guide-name>/guide/index.html` ->
`https://grails.apache.org/guides/grails{N}/<guide-name>/guide/index.html`
- `https://guides.grails.org/index.html` ->
`https://grails.apache.org/guides/index.html`
- `https://guides.grails.org/tags/*.html` ->
`https://grails.apache.org/guides/tags/*.html`
- `https://guides.grails.org/categories/*.html` ->
`https://grails.apache.org/guides/categories/*.html`
The `gh-pages` branch stays live (not archived) to serve redirects indefinitely.
The `grails-guides-template` repo itself can still be archived since the `gh-pages`
branch is independent of the source branches.

# Part 3 -- New System (After Migration)
## How Publishing Will Work After Migration
After consolidation, adding or updating a guide is straightforward. There are no
repos to create, no CI to configure, no secrets to set up, no scripts to curl.
### Adding a new guide (doc-only, no sample project)
This is the simplest case -- a guide that is pure documentation with no runnable
`initial/`+`complete/` sample apps.
1. **Create the guide directory**:
```
guides/my-new-grails8-feature/
├── toc.yml
└── guide/
├── intro.adoc
├── writingTheApp.adoc
└── summary.adoc
```
2. **Write `toc.yml`** (table of contents):
```yaml
title: My New Grails 8 Feature
authors:
- Your Name
---
introduction: intro.adoc
writingTheApp:
title: Writing the Application
guide: writingTheApp.adoc
summary: summary.adoc
```
3. **Write `.adoc` files** using AsciiDoc syntax. Use `include::` to pull in
shared snippets from `guides/common/` (e.g. `common-requirements.adoc`).
4. **Add an entry in `conf/guides.yml`**:
```yaml
- name: my-new-grails8-feature
title: "My New Grails 8 Feature"
subtitle: "Learn how to use the new feature in Grails 8"
authors: "Your Name"
category: "Grails Apprentice"
tags: [grails8, new-feature]
publicationDate: "15 Feb 2026"
grailsVersions: [8]
```
5. **Build and preview locally**:
```bash
./gradlew buildGuides
# Open build/dist/guides/my-new-grails8-feature/guide/index.html
```
6. **Submit a PR** to `apache/grails-static-website`. Once merged, the guide is
automatically built and deployed by `publish.yml`.
That's it. One PR, one repo, automatic deployment.
### Adding a new guide with sample projects
For guides that include runnable `initial/`+`complete/` Grails applications:
1. **Create the guide content in this repo** (same as above -- steps 1-4).
2. **Add `sampleProjectRepo`** to the guide's `conf/guides.yml` entry:
```yaml
- name: my-new-grails8-guide
title: "My New Grails 8 Guide"
subtitle: "A hands-on guide to building with Grails 8"
authors: "Your Name"
category: "Grails Apprentice"
tags: [grails8]
publicationDate: "15 Feb 2026"
grailsVersions: [8]
sampleProjectRepo: "grails-guides/my-new-grails8-guide"
```
3. **Create the sample project repo** in the `grails-guides` org:
```
grails-guides/my-new-grails8-guide/
├── initial/ <-- starter Grails app
├── complete/ <-- finished solution
├── settings.gradle <-- include 'complete', 'initial'
├── build.gradle <-- just builds/tests the sample apps (no doc publishing)
└── .github/workflows/
└── build.yml <-- runs ./gradlew check only
```
The sample project repo is simple -- no `githubactions-build.sh`, no
`apply from:` remote scripts, no doc-publishing metadata, no secrets needed
for pushing to `gh-pages`. It just builds and tests the sample apps.
4. **Submit two PRs**:
- PR to `apache/grails-static-website` with the guide content + YAML entry
- Create the sample project repo with `initial/`+`complete/`
### Updating an existing guide
1. **Edit the AsciiDoc** in `guides/<guide-name>/guide/*.adoc`.
2. **Update `conf/guides.yml`** if metadata changed (e.g. adding a new Grails version).
3. **Submit a PR**. That's it.
If the guide has a sample project repo in `grails-guides`, update the sample code
there in a separate PR.
### Adding a new Grails version to an existing guide
1. **Update `conf/guides.yml`** to add the version:
```yaml
grailsVersions: [6, 7, 8] # was [6, 7]
```
2. **Update AsciiDoc** if there are version-specific instructions (use AsciiDoc
conditionals or separate sections as needed).
3. **Update the sample project repo** (if one exists) -- either update the existing
`initial/`+`complete/` to the new Grails version, or add versioned directories
(e.g. `complete-grails8/`) if multiple versions need distinct sample code.
4. **Submit a PR**.
### How versioning simplifies with migration
In the current system, multi-version guides require maintaining separate Git branches
per Grails version, each with its own CI pipeline writing to `gh-pages`. After
consolidation:
1. **No more multi-branch complexity**: Guide version metadata lives in
`conf/guides.yml` with a simple `grailsVersions: [4, 5, 6]` list. The AsciiDoc
source is a single copy with version-conditional content if needed.
2. **Publish previously unpublished versions**: The 35 `grails5` branches with
distinct content and the 15 `grails-4` branches with distinct content can now
be published by adding their AsciiDoc and sample code during migration. These
were never published only because the CI scripts didn't handle them.
3. **Explicit version support**: Instead of inferring version from branch names
with inconsistent patterns (`grails4` vs `grails-4`), each guide declares
supported versions explicitly in `conf/guides.yml`.
4. **Single-pass build**: One Gradle build generates all guide HTML for all versions,
instead of each version branch triggering separate CI pipelines that race to
write to `gh-pages`.
5. **Easy to add Grails 7/8 guides**: Adding a new guide version is a YAML edit,
not a branch + CI + secrets setup.

## Comparison: Before vs After
| | Current system | After migration |
|---|---|---|
| **Create a new guide** | Run `create-guide.sh`, create GitHub repo, manually create workflow YAML, configure 3 secrets, push | Create `guides/<name>/` dir + `conf/guides.yml` entry, submit PR |
| **Where guide content lives** | Scattered across 94 repos | Single `guides/` directory in this repo |
| **How it gets published** | Push to guide repo -> CI curls scripts -> builds AsciiDoc -> pushes to gh-pages -> curls another script -> rebuilds index -> pushes again | Push to this repo -> CI builds everything -> deploys |
| **CI configuration** | Per-repo workflow YAML + 3 secrets + runtime curl of scripts | Single `publish.yml` in this repo |
| **Preview changes** | Must push to trigger CI; no local preview | `./gradlew buildGuides` locally |
| **Add a Grails version** | Create a branch, hope the CI handles it (it probably won't due to `build-guide` branch discrepancy) | Edit one line in `conf/guides.yml` |
| **Time to publish** | Minutes (CI cascade across repos) | Seconds (single build + deploy) |
| **Guide URL** | `guides.grails.org/<name>/guide/index.html` | `grails.apache.org/guides/<name>/guide/index.html` |
| **Repos to maintain** | 94 guide repos + 1 template repo | 1 repo (this one) + sample project repos |
