I'm experiencing some strange behaviour when combining the AspectJ compiler plugin with an annotation processor that generates sources.

I have Project A, the main project with annotated classes.

I have Project B, the dependency project with aspect classes and the annotation processor.

Ideally, what should happen, is upon compilation of project A, sources generated from annotated classes in Project A, using the annotation processor in project B should be compiled and saved in target/generated-sources/annotations/...

What actually happens is, upon compilation of project A, sources are generated in target/generated-sources/annotations/... and then generated a second time at the root of project A.

A workaround I found for this is to add <proc>none</proc> under <configuration> of the AspectJ compiler, but it's just a workaround. Am I missing something?

I've also found this question that seems to describe a similar issue.

  • This is interesting, but a rather complex situation. Please provide a minimal version of your situation which reproduces the problem. I know AspectJ and also Maven, but I do not feel so inclined to recreate everything from scratch, trying to guess what kind of annotation processor you have etc. Please publish an [MCVE](https://stackoverflow.com/help/mcve) on GitHub, I can take a look then and share my insights with you, if any. With only the POMs I cannot answer the question. – kriegaex Jul 29 '20 at 03:48
