Hi Renato,

This is a problem which has come to the surface in the last while and
yes it is most certainly a bug which needs rooted out and fixed!

I'm currently investigating gora-tutorial pom.xml [0], which has next
to no dependencies apart from data store implementations which are
used within the tutorial. It also seems to include a rather random
reference to the build-helper-maven-plugin, which I don't understand
as the src/main/java directory is effectively acting as
src/examples/java does in other modules.

I made a commit yesterday which I thought addressed some early
problems within the tutorial, but it seems that there is still some
digging to be done here. This is most likely to have happened during
the transition from Ant/Ivy to Maven for build lifecycle.

I have work to do for the next tow hours but I will certainly have a
look into this again tonight.

Thanks for reporting

Lewis
