Quarkus / MapStruct - Annotation Processing (build project or launchBeforeBuild)

[kjq]

Just developing, not running quarkus:dev, if I go to "build the project" or run any tests with launchBeforeBuild=true, I get errors that the MapStruct mappers are not correct as if the annotation processor did not run.

Running Maven in the CLI works fine and if I have launchBeforeBuild=false or proceed after the errors I can run and debug the tests without a problem (this is not acceptable though because it basically says everything is broken until I clear the workspace).

If I just build the project using the Java Project extension, I will get the errors but then running Maven -> Reload Project afterwards brings it back to the correct state (and no errors are displayed). Unfortunately, I cannot do this with tests if launchBeforeBuild=true.

Some things I have tried:

• Opening the single project only gives the same result
• Disabled m2e_apt "seemed" to get me closer but had other issues.
• Tried probably every post about annotation processing etc. regarding MapStruct and Lombok.

Environment

• Operating System: WSL2
• JDK version: JDK 17
• Visual Studio Code version: latest
• Java extension version: latest
• Java Debugger extension version: latest

Steps To Reproduce

Using the Java Project extension run Build Project or run a test case with launchBeforeBuild=true:

If I have launchBeforeBuild=false, build outside VSCode using Maven, the tests run fine and I can debug them.

Using the Java Project extension run Maven Reload Project right after brings it back to the correct state:

Expected Result

Since I am running the same as I would be with Maven in the CLI and not using quarkus:dev it should generate and recognize the mappings being generated through the annotation processor. The build and the generated mappings work fine in the CLI using Maven.

@kjq Could you provide a sample project for us to try the issue? thanks.
