title: Integrate Spock's test with Sonar
body: <p>I use spock to write test case and jenkins to run and publish my test cases.
  I was able to get the code coverage reported but sonar shows me <strong>only Java</strong> Unit test cases; the <strong>groovy test cases are totally missing</strong> </p>
  
  <p>The following pom.xml is used as reference

  <p>would anyone please know what I am  missing ?</p>
