I'm in the process of testing Maven's version constraint handling. I'm going to use different threads to document each issue found First the version format: The way we are specifying versions is similar to how OSGi handles versions i.e. major.minor.micro.qualifier However Maven doesn't use that scheme: http://docs.codehaus.org/display/MAVEN/Dependency+Mediation+and+Conflict+... instead it is major.minor.micro-qualifier-build So our jboss-5.0.0.Beta4 should be under maven jboss-5.0.0-Beta-4 for the version ranges to work properly.
