[PR] feat(build): publish nightly snapshot jars to the ASF Nexus snapshot repository [solr-mcp]
adityamparikh opened a new pull request, #220:
URL: https://github.com/apache/solr-mcp/pull/220
**⚠️ Needs credentials from an ASF committer before this can run: `ASF_NEXUS_USERNAME` / `ASF_NEXUS_PASSWORD` repo secrets are not provisioned yet. Eric Pugh or Jan Høydahl (org.apache.solr Nexus deploy rights) need to add them. Until then, the scheduled workflow will fail loudly on every run by design — see "Open question" below.**
## What / why
This adds a nightly *jar* publish, the Maven/Gradle-dependency counterpart to the nightly *Docker image* effort in #218 (not touched here).
Maven Central never accepts SNAPSHOT/nightly artifacts — that's a hard Sonatype/Central platform rule. The ASF-native destination for `org.apache.*` groupIds (this project is `org.apache.solr`) is the Apache Nexus snapshot repository at `https://repository.apache.org/content/repositories/snapshots`.
The project's `build.gradle.kts` already applies `maven-publish` and defines a `maven` publication (`group = "org.apache.solr"`, `version = "1.0.0-SNAPSHOT"`), but had no `repositories {}` block — nothing was ever published anywhere but `~/.m2` via `publishToMavenLocal`. This PR:
1. **`build.gradle.kts`**: adds a `repositories {}` block under `publishing {}` targeting the ASF Nexus snapshot repository. Credentials are read lazily via `providers.environmentVariable("ASF_NEXUS_USERNAME"/"ASF_NEXUS_PASSWORD")` — `.orNull` never throws, so `./gradlew build`/`test`/`publishToMavenLocal`/etc. all keep working with zero env vars set for every contributor who doesn't have them. Only `./gradlew publish` itself fails, loudly and clearly (`doFirst` check), when credentials are missing — instead of an opaque HTTP 401 deep in the Maven-publish plugin.
2. **`.github/workflows/nightly-jar.yml`**: a new scheduled workflow (2 AM UTC, matching #218's Docker cron) + `workflow_dispatch`, guarded to `if: github.repository == 'apache/solr-mcp'` so forks don't run it. Secret presence is checked inside a `run:` step (shell `[[ -n ... ]]`), **not** inside an `if:` condition — an earlier nightly workflow attempt in this repo's history (PR #155 / issue #15) referenced `secrets.*` directly in an `if:`, which is illegal YAML and caused a permanent parse-time failure with zero jobs ever running. #218 already fixed this pattern for the Docker workflow; this PR follows the same fix for the jar workflow.
3. **`dev-docs/NIGHTLY_JAR.md`**: new doc (mirrors `dev-docs/DOCKER_PUBLISHING.md`'s style) explaining the flow, how to publish locally, how consumers add the snapshot repository to their own Gradle/Maven build, and — most importantly — the credential gap below.
## Open question for Eric Pugh / Jan Høydahl
Not claiming certainty here: it's unconfirmed whether `org.apache.solr` is already pre-provisioned in ASF's Nexus for this specific sub-project (`solr-mcp`), the way it presumably is for the main Apache Solr project, or whether that itself needs requesting separately. Whoever provisions the `ASF_NEXUS_USERNAME`/`ASF_NEXUS_PASSWORD` secrets should confirm.
## Verification
- `./gradlew tasks --all` — `publish`, `publishToMavenLocal`, `publishAllPublicationsToAsfNexusSnapshotsRepository`, and `publishMavenPublicationToAsfNexusSnapshotsRepository` all resolve with no configuration errors.
- `./gradlew spotlessCheck` — passes.
- `./gradlew build` (full build, JDK 25, Testcontainers/Docker available) — **BUILD SUCCESSFUL**, all tests including `rat`, `spotlessCheck`, and the Testcontainers-based integration tests pass.
## Test plan
- [ ] ASF committer (Eric Pugh or Jan Høydahl) provisions `ASF_NEXUS_USERNAME` / `ASF_NEXUS_PASSWORD` as repo secrets
- [ ] Confirm `org.apache.solr` groupId is provisioned for deploy in ASF Nexus for this sub-project
- [ ] Trigger `nightly-jar.yml` via `workflow_dispatch` and confirm the artifact appears at https://repository.apache.org/content/repositories/snapshots

@epugh @janhoy — nightly *jar* to the ASF Nexus snapshot repo, the Maven-dependency counterpart to #218's nightly Docker image. Flagging up front: this needs `ASF_NEXUS_USERNAME`/`ASF_NEXUS_PASSWORD` repo secrets from whoever has `org.apache.solr` Nexus deploy rights before it can actually publish — the workflow fails loudly until then, by design. Also open: whether `org.apache.solr` is already provisioned in ASF Nexus for this sub-project specifically, or needs a separate request. See dev-docs/NIGHTLY_JAR.md.

I question whether we at all need publishing nightly SNAPSHOT jars anywhere. Users can check out and build the project to obtain those if they don't want to run on an officially released version. Can we simply skip this and simplify things?
