title: SonarQube: Multiple unit test and code coverage result files
body: <p>we have the following structure in our project:</p>
  
  <ul>
  <li>maven project 1</li>
  <li>maven project 2
  <ul>
  <li>module 1</li>
  <li>module 2</li>
  <li>module 3 </li>
  </ul></li>
  <li>maven project 3</li>
  </ul>
  
  <p>Project 1 and 3 have each one unit test and code coverage result file. They are no problem. Project 2 has three unit test and code coverage result files, one for each module.</p>
  
  <p>Now I want to show the unit test and code coverage in SonarQube. But I can only configure one result file (sonar.surefire.reportsPath and sonar.emma.reportPath).</p>
  
  <p>How can I configure the three files, or do I have to merge the files?</p>
