I want to enable AspectJ compiler in my IntelliJ Idea as I have several aspects that I'd like to be woven during compile time.
At the same time, I am using Lombok and Mapstruct in my codebase.
Those 2 require additional annotations processing, that must happen before ajc kicks in.
I have both plugins installed for Lombok and Mapstruct. Independently they work fine, source code is being generated. But when I enable ajc and tick Enable annotation processing options, and then build a project, I get:
Error:(9, 0) ajc: Internal error in the mapping processor: java.lang.NullPointerException at org.aspectj.org.eclipse.jdt.internal.compiler.lookup.FieldBinding.sourceField(FieldBinding.java:425) at

Also, I see a bunch of other ajc compilation errors as it is not able to locate methods that should've been generated by the Lombok.
How do I solve these issues?
Enabling Post-compile weave mode in IntelliJ solved it for me (https://www.jetbrains.com/help/idea/using-the-aspectj-ajc-compiler.html).
