Heh, I'm not sure if my crude observation re: SNAPSHOTs counts as a "finding". I can only manage to do the same as Maven thanks to my usage of Aether and liberal reading of source. If that's the best option available, it's surely not in the best interests of the broader Maven community. i.e. Now that I'm down this "low" in the stack, I can imagine that many of the Maven-interoperability issues that ivy had/has (I've not been near it for some years) are attributable to the lack of a usable specification of repository layouts, operational semantics, etc. So, when it "breaks", that's just a symptom of it not being implemementation-identical to maven/aether. I'm sure someone on this list knows where the bodies are buried. A brain dump along with a set of conformance tests would be immensely beneficial long-term. That would at least provide a basis for later improvements and migrations that third-party implementations could follow along with sanely.
