Ideally you need apache-maven-3.5.0 installed (at least 3.3.1), to compile with

mvn package # outputs hype.jar into target folder

For JRubyArt wrap hype.jar in library folder, put library folder in a hype folder (and put that alondside regular processing libraries in sketchbook/libraries linux etc). For propane put nested hype library in ~/.propane/libraries folder see how to install contributed libraries for propane.
