When trying to install the current version of m2eclipse (0.12.1.20110112-1712) I get an error which doesn't really help me:
Cannot complete the install because of a conflicting dependency.

My Eclipse version is 3.5.2 and I'm using it under Ubuntu. Maybe someone has an idea? Googling did only bring up error messages at the Eclipse marketplace without any discussion.
The solution is to install Eclipse 3.6 (Helios), which is not officially supported by Ubuntu 10.04. Now, m2eclipse could be installed without a problem.
This is not the most optimal solution, but at least it works now.
