title: Why are Jenkins "extended emails" not including extended information?
body: <p>We installed <a href="https://wiki.jenkins-ci.org/display/JENKINS/Email-ext+plugin" rel="noreferrer">email-ext</a> 2.24.1 into Jenkins 1.447.  We set "Extended Email Notification" "Default Content" to</p>
  
  <blockquote>
    <p>$PROJECT_NAME - Build # $BUILD_NUMBER - $BUILD_STATUS:</p>
    
    <p>Check console output at $BUILD_URL to view the results.</p>
    
    <p>Failed tests (regressions compared to previous builds):
    ${FAILED_TESTS, onlyRegressions=true}</p>
    
    <p>Changes: ${CHANGES, showPaths=true, format="%a: %r %p \n--\"%m\",
    pathFormat="\n\t- %p"}</p>
  </blockquote>
  
  <p>We went to a project, and selected "Editable Email Notification" and left the default settings, where "Default Subject" says $DEFAULT_SUBJECT and "Default Content" says $DEFAULT_CONTENT.</p>
  
  <p>In emails that come out, it's as if email-ext doesn't exist. I just see build information, nothing about the tests that failed or the changes since last success.</p>
  
  <p>Why do the emails not show Failed tests and Changes? And how do I debug this? Are there logs somewhere showing what is getting run?</p>
  
  <p><strong>Edit</strong>: I added "HALLOO" to the project "Default Content". Didn't show up.</p>
