There are two parts to Tycho:
1) the maven plugin that you add to the POM

The maven plugin allows maven resolves artifacts from a P2 repository in
addition to regular maven repositories.
I am not completely sure what the m2eclipse connector does, though. I know that it is able to detect that the
uimaj-ep-* modules are PDE projects and generates a PDE nature into the Eclipse .project file. I am not sure how it
handles artifact resolution within Eclipse, e.g. does one use the "Plug-in Dependencies", the "Maven
Dependencies" or both. Last time I tried tycho, I couldn't figure that out properly. My impression at the time
was that m2eclipse could not act as a resolver for dependencies in Eclipse for PDE projects. During my latest
experiments with UIMA, though, I temporarily had a state where I had both "Plug-in Dependencies" and
"Maven Dependencies" in a project and it seemed at least not to cause build errors.
Some experimentation should help;)
Well, currently you also need to make sure all required plugins are
installed in your eclipse
installation to run the UIMA plugins. As far as I know that is also the
PDE way, eclipse does
not download any dependencies for you itself.
One thing I find a little annoying currently is, that I always need
maven to generate the MANIFEST.MF file
and that the PDE tooling for this cannot be used. I guess these things
will work better with Tycho.
