title: How to fix "Test reports were found but none of them are new. Did tests run?" in Jenkins
body: <p>I am getting the error "Test reports were found but none of them are new. Did tests run?" when trying to send unit test results by email. The reason is that I have a dedicated Jenkins job that imports the artifacts from a test job to itself, and sends the test results by email. The reason why I am doing this is because I don't want Jenkins to send all the developers email during the night :) so I am "post-poning" the email sending since Jenkins itself does not support delayed email notifications (sadly).</p>
  
  <p>However, by the time the "send test results by email" job executes, the tests are hours old and I get the error as specified in the question title. Any ideas on how to get around this problem?</p>
