[GitHub] [netbeans] ducminh03 opened a new issue, #5606: Subprojects not recognised unless in child directory of root project

ducminh03 opened a new issue, #5606:
URL: https://github.com/apache/netbeans/issues/5606

   ### Apache NetBeans version
   
   Apache NetBeans 17
   
   ### What happened
   
   There are two projects `root` and `sub`, both of which resides in the same folder. `root` includes `sub`. On IDEs like IntelliJ IDEA, it correctly recognises project `root` with modules `main` and `sub`.
   
   However, NetBeans does recognise that there is one subproject, but its name is not shown:

   Double-click on that blank entry, and `sub` project will load, not as a subproject of project `root`, but as a standalone project (new root project).
   
   This causes problems when there are extra properties, version catalogues, etc... that `root` and `sub` share, which are defined in `root`'s `build.gradle` or `settings.gradle`. The subproject does not recognise `root` as its parent project, therefore `root` configurations does not apply to `sub`, which causes `sub` configuration errors.
   
   I realised that I can make `sub` project successfully recognise `root` as its parent project by moving `sub` folder into `root` folder and update `sub` project's path in `root`'s `settings.gradle`.
   
   ### How to reproduce
   
   **Step 1**. Create this directory tree:
   ```
   root/
   ├─ build.gradle
   ├─ settings.gradle
   sub/
   ├─ build.gradle
   ```
   
   root/settings.gradle
   ```
   rootProject.name = 'root'
   include ':sub'
   
   project(':sub').projectDir = file('../sub')
   ```
   
   root/build.gradle
   ```
   plugins {
       id 'java-library'
   }
   
   allprojects {
       ext {
           str = 'Hello'
       }
   }
   
   dependencies {
       project ':sub'
   }
   
   println ext.str.length()
   ```
   
   sub/build.gradle
   ```
   plugins {
       id 'java-library'
   }
   
   println ext.str.length()
   ```
   
   **Step 2**: Open project `root` by choosing `root` folder, and wait for project `root` to complete opening.
   In `root`'s `Sub Projects`, there is a blank line which represents unsuccessfully realised `sub` project.
   **Step 3**: Double-click on the blank line to open project `sub`.
   NetBeans would notify that the project is unsuccessfully loaded as follows:
   ![image](https://user-images.githubusercontent.com/17383640/222922568-4e192f52-5726-4496-8efd-f47fc9e08381.png)
   `sub` project's `Build Scripts` would also not have `root`'s `build.gradle`.
   
   **Step 4**. Now, close those two projects.
   **Step 5**. Move the folder `sub` into the folder `root` and change the content of `root/settings.gradle` as follows:
   ```
   rootProject.name = 'root'
   include ':sub'
   
   project(':sub').projectDir = file('./sub')
   ```
   The directory tree should be as follows:
   ```
   root/
   ├─ build.gradle
   ├─ sub/
   │  ├─ build.gradle
   ├─ settings.gradle
   ```
   **Step 6**. Reopen `root` project.
   Now, `sub` project is listed as a subproject `:root:sub` in `root`'s `Sub Projects`
