Run mvn package -Pstart-server.
This will compile and packge your plugin, then download all the necessary dependencies to run the server which will be started in the folder server.
Note: the code will only compile with JDK 1.6 (cause: @Override for interface methods)
For Eclipse Users: -to run the server from eclipse, create a Maven Run Configuration, set Goal to "package" and Profile to "start-server" -to submit your own changes to your own github repository, you need to add your ssh key to your $HOME/.ssh folder (github help has further information)
