title: Azure Devops Condition Build Validation
body: <p>Is there a condition that checks in Build validation Was there a change in a particular folder?
  I have a JOB that is targeted to a specific folder and I want in build validation it will not run this Job if there was no change in the files in the folder.</p>
  <p>And when they do Merge I want them to run even if there was no change. (They will run normally as if there are no conditions)</p>
