Yeah, we want to be able to build from either the parent (and build everything) or from the child (and just build the child) but we need the information in the parent when the child is being built. As a result, it looks like we are stuck with the 2-way dependency (at least according to what I could understand from the maven site and the maven book). In maven1 we created a plugin which would walk the source tree so that the parents did not have to know about the children. The nice thing about this is that you could drop a new project in the source tree and it would get picked up and built automatically. All the children only knew about one single master POM which provided them with a set of properties and shared dependencies. I think we are going to have to just be stuck with the tight coupling in maven 2 though. I would be happy to know I am wrong on this though so feel free to correct me. :-) -AZ > Just play around with it a bit, Maven is very flexible in this way.
