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 :-/
