Annotation processing occurs during compilation, so normal debugging won't work. If you want to debug it in the context of you project, you can use IntelliJ remote debugging, while having Gradle or Maven in debug mode. Then you can put breakpoints in the Annotation Processor's files.

See Debugging an Annotation Processor in any project.
