Subject Re: Tycho vs Felix for TextMarker build
Date Fri, 27 Apr 2012 12:40:31 GMT
  A short update:

Until now, I just failed to get the build process working with Tycho. As 
far as I know right now, Tycho can only resolve dependencies which 
artifacts are bundles, and there is a workaround for bundles that are 
built with a pom-first approach 

The situation is as follows:
- uimaj-textmarker: normal maven project (no bundle) with the 
implementation of the rule language
- uimaj-ep-textmarker-engine: plugin project built pom-first (felix) 
that publishes the implementation of uimaj-textmarker
- uimaj-ep-textmarker-ide: plugin project built manifest-first (tycho) 
that depends, for example, on the uimaj-textmarker

Right now, the uimaj-ep-textmarker-ide project cannot resolve 
dependencies to the implementations that are only published by a plugin, 
e.g., uimaj-ep-textmarker-engine or uimaj-ep-runtime. Maybe I've done 
something wrong here...

Tycho is good at resolving dependencies for p2 repositories, but maybe 
not robust enough for mixed projects. I'll read and try some more stuff, 
but I am not very confident. If there is no progress at all, I'll write 
the felix and tycho developers for some advice.

Has anyone an idea?
