Cannot launch Java project in workspace with several Java projects

Hello, I’m experiencing a very frustrating problem with the Visual Studio Code launcher for my Java/Spring boot/AspectJ/Gradle multi module project.

Description

All is working fine if my project is the only project in my VScode workspace. But as soon as I have several projects in the workspace, I get errors related to Aspects when running my project.

Steps to reproduce

After wasting my time on trying to make my project work, I could finally reproduce the problem on 2 minimalistic projects. Here is how to proceed:

1. Use a new empty workspace

2. Clone the 2 following projects from command line (not in vscode):

• https://github.com/pelmato/poc.git
  Project "poc" is a Gradle multi-module project with
  - module "poc-a": a spring boot project with a simple endpoint.
  - module "poc-b": a simple gradle module which defines and use a basic Aspect.
  Please also note that poc-a needs to set an injected service into poc-b aspect.
• https://github.com/pelmato/other-poc.git
  Project "other-poc" is a simple copy of "poc" with package name changed.

3. Import the "poc" project into the vscode workspace.

4. Run and Debug the "poc" project (using the "POC" launcher from poc/.vscode/launch.json).

So far so good.

5. Stop the POC debug session.

6. Import the other-poc project into the vscode workspace.

7. Run and Debug the "other-poc" project (using the "Other POC" launcher from other-poc/.vscode/launch.json).

Expected: the other-project is run.
Observed: exception:

Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.

8. Call the command "Java: Clean Java Language Server Workspace"

Now both projects have the same error.

9. Remove "other-poc" project and re-clean the Java Language Server Workspace. Now the error is gone.

Any help would be greatly appreciated.

PS: tested on version 1.42.0, but also affects previous versions.

Reproduce el fallo utilizando los repositorios poc y other-poc y sus lanzadores de .vscode/launch.json; después, sigue el stack trace a través de AspectConfiguration.java y del comando workspace-clean de Java Language Server. Se considera terminado cuando cada proyecto se inicia de forma independiente en el mismo workspace sin la NoAspectBoundException, incluso después de limpiar el workspace del servidor de lenguaje.
