title: Duplicate changelogs in jenkins pipeline script with SVN
body: <p>This question is basically the same as <a href="https://stackoverflow.com/questions/36197131/duplicate-changelogs-in-jenkins-pipeline-script">this one</a> except I'm using subversion, and no plugin update has done the trick for me.</p>
  
  <p>I'm loading my Jenkinsfile script with a multibranch pipeline setting, and the changelog gets duplicated at each new <code>checkout scm</code>.</p>
  
  <p>Since in my build I'm using multiple workspaces, allocated through <code>node</code> inside <code>parallel</code> blocks, I'm calling fresh checkouts for each of them, and the changelog duplication is getting a bit annoying.</p>
