Technically, the artifacts for 4.1 are also missing. Not sure we care, though.
The 4.2 artifacts are now published to the JBoss Releases repo, e.g. the domain jar is at: https://repository.jboss.org/nexus/content/repositories/releases/org/rhq/rhq-core-domain/4.2.0/ To add RHQ dependencies to your Maven project, add the following repo to either your pom or settings.xml: <repository> <id>jboss-public-repo-group</id> <name>JBoss Public Repository Group</name> <url>http://repository.jboss.org/nexus/content/groups/public/</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> Note, I also added instructions on publishing Maven artifacts to the RHQ dev wiki: http://rhq-project.org/display/RHQ/Publishing+Maven+Artifacts
