This is not a rant against you, I like you personally. I just don't like it when people I like, like maven :P Most of the criticism you have against Maven do not apply to Tycho. Indeed, Tycho is not the master of your dependencies, you still have to specify them by yourself in a Manifest, and Tycho will use it to build a target platform that is OK for building your bundle. The approach is fairly good. I maintain a build with Ant and I have to admit I am almost the only one who can work with it easily in our team, and that we spend a lot of time maintaining target platforms. I've done some work with Maven, and I really feel that the build is easier for everybody with Tycho. The only difficulty is that Tycho does not allow you ugly hacks in builds. A legacy Ant-based build allows you to write very crappy scripts to solve some problems. Tycho forces you to get closer from the OSGi and Maven way. Writing crappy build with Tycho is almost impossible, so that basing the build on Tycho forces you to have a better quality. Concretely, Tycho would not let you to have a Manifest.mf.eclipse35 and a Manifest.mf.eclipse36 in the same bundle with the manifest that is chosen according to a flag in the build. It would force you to leverage constaints in dependencies. And if you are really in need of such a hack, you can leverage profiles, that allow you to do ugly things, but in a more structured way. You should give a try to Tycho. For example try building EGit/JGit, I think you'll for sure find it pretty straightforward and you'll understand how easy it is to get into the project thanks to it. By the way, I think that the best way to convince you is to show you concrete results. I keep on working on that stuff, on once I am successful, I'll simply show you the result. Then you'll probably be more friendly with Tycho ;) --
