Jason, I'm really, REALLY, glad you have taken an interest in m2 migration :-) Your experience with other such migrations can surely help us. Alright so now you can guide us.
So we shall hardcode the parent <version> in all pom.xml and remove the <version>. element for that project itself. That should help us do a single build w/o the -N. What else would u advise ? Thanx Prasad On 6/26/06, Jason Dillon <[EMAIL PROTECTED]> wrote:
I don't see what the problem is. Is this just about putting the version in the parent element? I don't really like that it has to be there, but I am okay with it and using the release plugin to manage that value, which is the main benefit of the release plugin IMO. Or am I missing something? I've recently converted a number of large m1 projects to using m2 and have run into very little issues. Most are related to use of custom jelly, requiring new mojos which is not a big issue. Others being due to projects dependent on those mojos, and keeping them under a separate lifecycle, and expecting that users will download them not build them. So the top-level pom.xml just says <version>1.2-SNAPSHOT</version> and then all children have <parent>...<version>1.2-SNAPSHOT</ version></parent>. This works very well to *build* and is only a slight pain when releasing, but as I mentioned the release plugin handles this. I would obviously rather that it inspect the relativePath first... up until it finds a version and if the parent is not available then pull from the repo... but that isn't gonna happen any time soonish for us to benefit from. IMO, we need to adapt to how m2 works now and then grow with it as we get features/bugs fixed and implemented. --jason On Jun 26, 2006, at 7:21 PM, Prasad Kashyap wrote: > Yes, that's the ideal situation and we very much desire it.
