Building multi project java workspace with cross dependent modules(Java9)

[RedIODev]

[provide a description of the issue]

Environment

• Operating System: Windows 10
• JDK version: 19
• Visual Studio Code version: 1.72.2
• Java extension version: 1.12.0
• Java Debugger extension version: 0.45.0

Steps To Reproduce

1. Open a folder in vscode
2. Create a file structure like this:
3. Open the folder as a multi project workspace like this:
4. Make the module main depend on sub1 and sub2
5. (no errors from linter) run the main

Current Result

Error: Cannot resolve the modulepaths/classpaths automatically, please specify the value in the launch.json

Expected Result

Runs the main modules Main with sub1 and sub2

Additional Informations

I already tried to set the module and classpath variables in multiple ways: as relative paths from main project, as absolute paths with ${workspaceFolder}... , and with and without $auto as part of the lists. I couldn't find good information about these 2 options and how to set them correctly. I am mimicking a eclipse multi project solution with modules and cross requirements since I discovered A: that the VSCode extension is based on eclipse and B: neither of them support "normal" single projects with multiple modules. But the nice menu to add in workspace dependencies to the other projects from eclipse is missing in vscode,
