title: How to compile the code using clover open version 4.2.0
body: <p>i was able to compile my source code and generate the instrument classes(including xxx-clover.war) using mvn clover2:instrument command using clover 4.0.6 maven plugin.
  When I tried with clover open source 4.2.0, I wasn't able to execute any clover goals like instrument, clover, setup.</p>
