Depending on later Maven Plugin 2.x releases is a mess as they include all sorts of different dependencies that result in upper bounds errors with recent plugin POMs.

It looks like it's fixed in 3.0-rc-1, but that's a big step just for some minor POM cleanup in dependent plugins.

Please release a Maven Plugin 2.x with plugins parent POM 2.35 and all necessary fixes.

CC oleg_nenashev who probably was the one to do it for 3.0-rc-1.
