title: How to do sonar job separately in jenkins for maven 3 project
body: <p>I am configuring sonar plug-in in Jenkins to execute on Maven 3 projects.</p>
  
  <p>Currently my maven project is scheduled to build when a code change in svn and also for every 2hrs </p>
  
  <p>Now I want to run the sonar on the same project only once in the night time, this should not impact the regular builds.</p>
  
  <p>I installed Jenkins Sonar Plugin and could able to add the sonar in the 'Post Build Actions' of the project configuration, and the everything build fine. But in this case the sonar is running each time after the project build is done, I want to run the sonar only at the night time.</p>
  
  <p>In my approach I did not included sonar maven plugin in pom file, since I want to use Jenkins sonar plugin</p>
  
  <p>Please let me know what changes I need to do from pom end and Jenkins end.</p>
