jitsi-videobridge-groovysh is an OSGi bundle that gives full access to the Jitsi Videobridge internals through a Groovy Shell.
To build the bundle run
mvn package
Alternatively, you can drop org.jitsi.videobridge.groovysh-1.0-SNAPSHOT.jar somewhere in your classpath and tell the bridge to launch
org.jitsi.videobridge.groovysh.GroovyShellActivator
To tell the bridge to launch the groovy shell activator, put this bundles.txt file under ~/.sip-communicator
To access the groovy shell run
socat -,raw,echo=0,opost TCP:127.0.0.1:6869
If you wish to run it in a production environment you'll need to wrap it around an ssh shell.
