Hi Ryan,
Cellar 3.0.x works only with Karaf 3.0.x (and there are still some
pending issues to fix before that).
My advice is to use Cellar 2.2.x (latest) with Karaf 2.2.x (latest):
it's the stable match.
I created Cellar 2.3.x branch in order to work with Karaf 2.3.x, I have
a couple of issues to fix on this branch before cutting a first Cellar
2.3.0 release.
Regards
JB

I am still running into a bit of trouble with Cellar 3.0.0-SNAPSHOT and
am not sure if I should back off to 2.3.0 for now (since I'm starting
pretty fresh with Karaf, I figure I might as well start with 3.0.0).
Karaf 3.0.0 has been working great so far, but I feel like I have to
be doing something wrong with Cellar. I had gotten the integration
tests partially running by upgrading to pax-exam 2.6. I then worked
through one or two other issues. I'm now getting NPEs from the child
instances in the integration tests when I try to install cellar on them.
I decided I should probably try installing Cellar on a plain running
Karaf 3.0.0 instance, here's what happened when I added the repo and
installed the cellar feature:

Is there a current known stability issue in Cellar 3.0.0 currently? Can
I use Karaf 3.0.0 and Cellar 2.2.5? Obviously there is always a risk of
issues with in-development software, I was just hoping to get a head
start. :)
Let me know if I should open an issue for anything, or if I can get
anymore information. When I debugged the NPE I was receiving in the
Karaf child instance in the integration tests, the NPE was caused by a
null feature url (even though the cellar feature url was being passed in).
