title: Jenkins - Configure Jenkins to poll changes in SCM
body: <p>I am working with jenkins and I would like to run the maven goals when there is a change in the svn repository. I've attached a picture with my current configuration.</p>
  
  <p>I know that checking the repository every 5 min is crazy. I would like to run it only when there is a new change, but I could not find the way. Anyway, it is not checking the repository. What am I doing wrong??</p>
  
  <p>Thanks in advance<img src="https://i.stack.imgur.com/oPlwM.png" alt="enter image description here"></p>
