Re: [p2-dev] Does the p2 publisher understand OSGi Provide-Capability / Require-Capability ?

Hi Tobias,

Thanks for following up. Yes, after some trial and error I got it working and this was my solution:
http://git.eclipse.org/c/tcf/org.eclipse.tcf.git/commit/?id=972ab04adee81615d09beebe9b3798eeb862395c

Thanks,
Martin

I suppose you can get help with the syntax here: http://wiki.eclipse.org/Query_Language_for_p2

Note: You do *not* want to use "metaRequirements", but rather regular "requirements". Meta requirements are for requirements on the installer/director and not for requirements of your artifact. When using metaRequirements, your installation will be broken when using a separate runtime for the director.

AFAIK, you got this working, right?
