Well sure - here you don't specify the project dependencies. You specify
the dependencies
for each compile.

It supports project dependencies; but not cyclic ones. (I don't know of
any IDE that
supports that (without having to build the annotations.jar by hand and
then not let the project
be dependent on each other )
I could probably tell it to point to the build/classes directory instead
of the project;
but that is still horrible - it does not remove the cyclic that still
exists here.
To resolve it you would need to move the search/validator tests to
annotations or
remove the AnnotationConfiguration depenendency in the tests...
