How to build a list of classes annotated with my custom annotation?

Question

I want to get a complete list of classes in the application which are annotated with @Custom annotation. What is the best mechanism for this operation?

Answer 1

The easiest way would be to use an IDE as Jesus suggested.

But you could also

• write an annotation processor that logs all occurrences of the annotation
• write an AspectJ aspect and declare a warning for this annotation (I know, warning is probably not what you want, but there is no INFO in AspectJ)
• use ASM to check the byte code for the annotation
• use a Source Parser to check the source code for the annotation

Beware: All of these are tricky. The AspectJ solution should be the simplest.
