To avoid circular dependencies and to be able to use a newer version of
the bundleplugin in the modules without always releasing the parent pom.
While it seems to be a nice idea to put all versions into the parent
pom, I'm coming more and more to the opinion that this is a bad idea if
your project consists of several modules that are released independently
from each other.
I think the problem might be that some of the plugins are in the same
project hierarchy as where they are used. It might make sense to put
those plugins in a different (part of the) hierarchy.
