CommandHelper adds simple command aliases, complex macros, and the ability to script your own commands and events into Minecraft, using the MethodScript scripting language.
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". If you get a message about tests failing, try running:
mvn -Pprovisional-build clean package install
