We should depend on released stuff whereever possible. As the
configuration stuff is nearly the only stuff which has a final release,
it just there that we use the version. Now, why it fails, I don't know
as these artifacts should be in public repositories.

Using the mvn dep mgmt for dependencies that come out of the same
project is imho bad and doesn't work as soon as every module has
separate release cycles. So while it is general useful to have all third
party versions in the root pom, it doesn't work for artifacts of the
same project. So this is the reason why they are hard-coded in some poms.
