Is the cocoon build really trying to rely on transitive dependency
verions? Very bad idea. Versions of every dependency cocoon uses
directly or indirectly should be specified in the managedDependencies.
The problem is that the groupId of the Avalon framework changed and
that's the root of all evil in this case. We ever never need a
dependency on Avalon 4.1.3 but how to express this in the
managedDependencies section?
The only chance for us is configuring "exclusions" but first you have
to figure out that you have to do it at all (here the dependency
module comes into play).
I have also experienced very strange behaviour of the dependency
resultion mechanism e.g. I exclude avalon-framework from being pulled
in by commons-logging but then, when I use commons-beanutils, which
pulls in commons-logging, the avalon-framework dependency is used again.
TBH, I have no idea why the dependency resolution is still buggy after
such a long time after the first final Maven 2 release :-/
Can you point me at the poms I should look at to see this?
If you refer to the commons-beanutils/commons-logging problem, here is a
stripped down variant of a custom project of ours that reproduced the problem:

Run "mvn dependency:list -P use-snapshots" and "mvn dependency:list -P

avalon-framework.
