Re: [m2e-dev] Trying to set up a build of a New Thing

As I commented in TYCHO-540, I am unable to reproduce the NPE. Make sure
you use Maven 3.0 final and not one of beta or rc builds.

As for repository, generally, we recommend using standard update site
url, but you can use ``S'' repository as well.

I'm trying to configure the pom to build a new component that is
expected to work with the 0.12 release.

I am failing to figure out what to use as the URL for the appropriate
p2 repo. There are a lot of digits there, but it doesn't seem to me
that and of the directories under N or S match up with the released
version of the 0.12 core. In any case, whatever experiment I've tried
come up with a null pointer exception in tycho.
