I\'m currently evaluating maven to improve our build process. The building and creating of normal jar files works so far, although I\'m not entirely happy with the Maven IDE
Tycho does what you need. Now in 2012, it is mature and usable set of maven plugins. I can only recommend it.
The quality of the documentation has obviously not changed very much since 2009. It may be difficult to get Tycho running. We managed to understand Tycho and we've been successfully using it for building a considerably large Eclipse RCP application for more than a year and a half. We adopted a manifest-first approach, where all the plugin(project) dependencies are defined in MANIFEST.MF. The final product of our build is an executable application and also a p2 site for easy updates. All done by maven build.
