How to process source level annotation using Reflection(not using Abstract Processor or APT) in Java?

Question

I can create a processor using Reflection to process the run-time level annotations, but how can i process the source level annotations using reflection?

Is there a reason not to use AbstractProcessor?

As the RetentionPolicy APIdoc states:

SOURCE

Annotations are to be discarded by the compiler.

So the answer is no. You either process annotation with @Retention(SOURCE) at compile time or they vanish.

If you process them at compile time implementing an AbstractProcessor and registring it via system properties or configuration of maven-compiler-plugin to the compiler is the usual way.
