The POM for jboss-aop-mc-int-2.0.0-SNAPSHOT has a dependency on jboss-commons-core-2.0.4.Alpha2. This, in turn, has a dependency on jboss-commons-logging-spi-2.0.2, which is not available in the repository (there's only 2.0.4.GA in http://repository.jboss.org/maven2/jboss/jboss-common-logging-spi/) and causes any project depending on jboss-aop-mc-int-2.0.0-SNAPSHOT to break. The actual break, I suspect, is in the jboss-aop-mc-int POM which specifies that it requires commons-core-2.0.4.Alpha2 and this prevents maven from using commons-core-2.0.4.GA. http://repository.jboss.org/maven2/jboss/jboss-aop-mc-int/2.0.0-SNAPSHOT/...
