How to generate list of services?

Question

I've written an annotation processor that I'm using to map classes to integer ids. My generated stub looks like:
//Source
@MyAnnotation
public class Foo
//Generated stub
public class FooStub extends com.kitfox.Stub {
    public int getId() { return 1; }
    public Class<Foo> getStubClass() { return Foo.class; }
}I would also like to generate an index of all com.kitfox.Stub that I can place in /META-INF/services. Unfortunately, the apt mechanism seems to only present the annotation processor with files that don't have existing .class files generated which makes it difficult to integrate incremental changes into the build process.
Is there a way to force annotation processing to handle all files on the source path regardless of whether .class files exist?
Is there some other way to generate services indices? I imagine there would be a lot of folks wanting to do this.

His generator also handles incremental compilation.
