How to Check References of Annotated Methods

Question

I'm trying to find a way to check my classes for references of methods with a particular annotation (think "Deprecated").

As far as i see it, analysing byte code won't work because it doesn't contain any annotations.
Using APT doesn't really help because i need the references to the methods, not the annotated methods themselves.

So, what options do i have?

The best i can come up with is compiling a list of the annotated methods followed by a full code analysis, checking every method call against the list.
Is there a way to do that efficiently in an eclipse plug-in or an ant task?

In another question I asked for a Java parser of the Java language. For my analysis of code I use this one. Perhaps it's good for you, too.

Frankly i can't remember what i needed this for. But i believe i built it into our Eclipse plugin and Eclipse will do the parsing for me. – Stroboskop Apr 19 '13 at 09:01

Analysing bytecode will works! ASM for an example is handling annotation very well.

wait... you're right. What made me think annotations don't get compiled to the byte code? – Stroboskop Nov 06 '09 at 14:26

Using the Reflections library, it's simple as:

Reflections reflections = new Reflections("my.package", new MethodAnnotationsScanner());
Set<Method> deprecated = reflections.getMethodsAnnotatedWith(Deprecated.class);
