The Maven plugin for building RHQ Agent plugins is now at version 1.0.
The bits are already available on JBoss public repositories and on Maven Central.
The version bump is mostly an indication that it is now considered stable.
The only feature added is an enhancement to the remote deployment mojo: you can now trigger a plugin deployment on all the agents (works with RHQ 4.12 servers and above).
This allows to easily apply continuous integration and continuous delivery principles to the development of RHQ Agent plugins.
