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

[Benson Margulies <bimargulies@xxxxxxxxx>]

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.
