anchor.diff:  
     If set and Jenkins is configured to poll for changes, Jenkins will ignore any revisions committed by users in this list when determining if a build should be triggered.
     This can be used to exclude commits done by the build itself from triggering another build, assuming the build server commits the change with a distinct SCM user.
  -  Using this behaviour prevents the faster `git ls-remote` polling mechanism.

     It forces polling to require a workspace, as if you had selected the <<force-polling-using-workspace,Force polling using workspace>> extension.
   
     Each exclusion uses literal pattern matching, and must be separated by a new line.

  If set and Jenkins is configured to poll for changes, Jenkins will pay attention to included and/or excluded files and/or folders when determining if a build needs to be triggered.
