title: Does mvn sonar instrument analysed classes
body: <p>What exactly does <code>mvn sonar:sonar</code>? does it instrument classes to measure code coverage? or it just sends sources to the server?</p>
  
  <p>to sum it up: can i safely do <code>mvn verify sonar:sonar deploy</code> and be sure my package is not instrumented in any way?</p>
