The negative side is that the transitive dependency analysis performed by certain versions of maven appears to be flawed.  The specific example I had this morning was caused by the inclusion of two different versions of jboss-test in our poms.  The old version was disabled but this also disabled some of the dependencies of the newer version!

The consequence of this was that a number of tests within deployers-vfs were failing because the oswego library was no longer on the classpath.

This is what I have done.  They are now listed in dependencyManagement sections and these supplement the dependency specifications in the pom.  This can still be overridden locally if needed.

I don't believe there is any way to force the build to terminate if you have a conflict.  The resolution mechanism gives precedence to the version which is configured closest to the pom IIRC, unless it is specified in the dependencyManagement section.

Yes, that would also need checking in that case.
