Yeah, we also have some JIRA issues related to the support of P2 for Apache Directory Studio, which is released an RCP app and an update site for installation in Eclipse. I have yet to find the time to dive into P2 and integrate the generation of the repository in our build.
Also, we're looking at Tycho for a long time now and maybe we can someday make the switch from our custom Maven build (Tycho didn't exist at the time we moved to Maven, so we had to find a way to build Eclipse plugins).
Regarding the fullscreen plugin integration, for us the painless solution is really to include the jar of the plugin in our internal Maven repository.
When building the OS X versions of the RCP application we would pull the plugin from the repository and include it in the distribution.
If and when the plugin becomes available in a central Maven repository, we would get rid of our copy to access it directly from there.
Many thanks for everything, Alex! (and again, apologies for the stupid mistake...)
I really love the ability to use Studio as a fullscreen app on OS X Lion.
