Descripción
I managed to open a multi-module maven project in VS Code and set up the launch.json correctly. I can debug the project and the breakpoints are respected in the main module. When I set a breakpoint in a referenced module, the execution will break, but I see a decompiled version of the class with the following comments:
// Failed to get sources. Instead, stub sources have been generated by the disassembler.
// Implementation of methods is unavailable.
I added the plugin in pom.xml for that module to generate the source from maven and the source. Then I used mvn clean install and the source code JAR was generated successfully under the target folder for the specific module.
I tried to launch the debug again, and nothing worked. I still see the decompiled version of the class.
I configured "sourcePaths" in launch.json to point to the generated source JAR and it didn't and didn't work. I tried to point to the folder, relative path, absolute path, and with/without the filename, but nothing worked.
I appreciate your help to find a resolution to this issue.
Environment
- Operating System: Windows 11
- JDK version: 1.8 and 18

Steps To Reproduce
- Open Java multi module maven project in VS code and wait until its fully loaded

- Start debug
[attach a sample project reproducing the error]
attach logs
Current Result
Breakpoint works only with the main module. The breakpoint in the other module works but source code is not used.

I tried all possible steps to resolve this problem but nothing worked.

Línea de trabajo
Comienza reproduciendo la configuración multi-módulo utilizando los pom.xml y launch.json referenciados, con breakpoints en el módulo principal y en los módulos referenciados. Investiga cómo sourcePaths resuelve el source JAR generado bajo target y, después, verifica que los breakpoints de todos los módulos muestren el código fuente en lugar de clases decompiladas.
