Intellij + Ajc + Lombok/Mapstruct

Hi I had similar issue.

The fix was to let aspectj-maven-plugin to only start weaving after classes are compiled.

It describes in more detail here https://www.mojohaus.org/aspectj-maven-plugin/examples/weaveDirectories.html

I needed to:

(1) Specify folder where already compiled classes will be via <weaveDirectories >

(2) Change the phase of maven-compiler-plugin lifecycle to be run "process-classes" or later.

This is how my pom looked like.

Enabling Post-compile weave mode in IntelliJ solved it for me (https://www.jetbrains.com/help/idea/using-the-aspectj-ajc-compiler.html).

if you have aspect sources with the same project then you should add a few line codes to the @jun-huh answers and delete <aspectLibraries>. The below pom.xml is for if you use your aspects with the same project.
