I have a working project on Spring Roo 2 M3. I realized that i needed a new finder apart from the ones that i created when i was bootstraping the project. I generated the finder in the roo console:
finder add --entity ~.domain.Usuario --name findByUsername
It created the right annotation in the java repository
@RooFinder("findByUsername")
and the method in the repository aspect
public abstract Page<Usuario> UsuarioRepository.findByUsername(String username, Pageable pageable);
but it didn't generate that finder in the service neither the service implementation like the other finders that i previously generated.
I googled it for some days and tried to fix it my self but i made no progress.
note: this already happened to me on other spring roo 2 M3 project some months ago. I had the same problem for like a week and then after many random tampering with the code finally the roo console triggered the changes but i couldn't figured out why it worked.

After analyze your issue, seems like some problem with the Spring Roo 2.0.0.M3 metadata listeners affects to the service generation when a new finder is included.
This problem has been fixed in Spring Roo 2.0.0.RC1 and it will be published really soon.
Anyway, if you make push-in of the findByUsername method, the service interface and the service implementation must include it.
Let me know if you have any problem with that!
Hope it helps,
