Example output that shows that classpath resolution is delayed until compile phase:

I have added a validate-classpath mojo just in case one want to still perform the class-path-computation in the verify phase.
This change also proofs that the additional resolving via the Equinox Resolver is only necessary for classpath computation and not for project order.
