I think that for that we want at least to have no library version

parent or a parent of the parent that would only do that but have the same lifecycle than
gatein, not released apart, or maybe that).
Then I think each packaging has to explicitely declare what it uses because inheritance
will surely not work in that case.
Yes, we'll have to be explicit.
Comparison then would be done between poms.
That would work (I feared that we would have a pom and an Ant)
Version update would happen at the common place.
Versions are already defined in the root pom for most libraries right ?
