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 the failure using the poc and other-poc repositories and their .vscode/launch.json launchers, then follow the stack trace through AspectConfiguration.java and the Java Language Server workspace-clean command. Done means each project launches independently in the same workspace without the NoAspectBoundException, including after cleaning the language-server workspace.
