CommandHelper adds command aliases and repeat-last-command functions.
You need to have Maven installed (http://maven.apache.org). Once installed, simply run:
mvn clean package install
Maven will automatically download dependencies for you. Note: For that to work, be sure to add Maven to your "PATH".
