I'm trying to use Groovy with Seam. I have created a .groovy file (a working Java entity) at hot directory. When Eclipse builds the workspace it will throw the following error:

BUILD FAILED
/home/nacho/workspace/keene/build.xml:101: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, /home/nacho/workspace/keene/src/main/es/iiso/keene/candidato/modelo/Candidato.groovy: 15: unable to resolve class es.iiso.keene.TipoCandidato
@ line 15, column 1.
   import es.iiso.keene.TipoCandidato;
   ^
/home/nacho/workspace/keene/src/main/es/iiso/keene/candidato/modelo/Candidato.groovy: 33: unable to resolve class LenguajeDeProgramacion
@ line 33, column 15.
        private List<LenguajeDeProgramacion> lenguajesDeProgramacion;
                 ^

2 errors

It looks like it can't find my own classes (es.iiso... are mine).

The project has been generated with seam-gen.

Any ideas?
