Compiling and Running the System

The code is shipped as a multi-module maven project. The root project contains two modules: kata and benchmark (and benchmark references kata). To install the project, simply ask maven to do so:

To run the benchmark (it takes around 40 minutes):

mosser@azrael potter$ java -jar benchmark/target/benchmarks.jar
