Question

Imagine the following:

@MyAnnotation
public class A { ... };

@MyOtherAnnotation
public class B { ... };

If a class is annotated with @MyAnnotation, an extra @MyExtraAnnotation should be added before annotation processing. So, after that step, we should have:

@MyExtraAnnotation
@MyAnnotation
public class A { ... };

@MyOtherAnnotation
public class B { ... };

Is this possible? If yes how? Thanks.

You should look at the process-sources phase of the lifecycle, or possibly the annotationProcessors configuration of the maven compiler plugin.

I’ve not found a plugin that “adds annotations”, but is certainly should be possible to create one to do just that.
