help with first simple benchmark test

[gitted]

So I have a simple benchmark like this:

public class JustATest1 extends Benchmark{

    @Param({"10", "100", "1000", "10000"}) private int length;

    public void timeNanoTime(int reps) {

        for (int i = 0; i < reps; i++) {

            System.nanoTime();

        }

    }

    public static void main(String[] args) {

        CaliperMain.main(JustATest1.class, args);

    }

}

This benchmark is inside a maven module, in a multi-maven project that i have using IntelliJ version 12

Now how do I go about running this via IntelliJ and/or command line?   I added caliper to my pom.xml so I am not exaclty sure where the .jar will be either.
