title: SVN environment variables not available in Jenkins
body: <p><a href="https://stackoverflow.com/questions/31009589/get-jenkins-environment-variables-in-execute-shell">this</a> solution doesn't work for me :-(</p>
  
  <p>I want to use SVN_REVISION in my Ant build.xml</p>
  
  <p>SVN_REVISION and SVN_URL are listed in /env-vars.html
  but if I want to use them in Ant or in the execute shell as above (e.g. echo ${SVN_REVISION}) none of the values are set.</p>
  
  <p>Though the correct revision is displayed when checking out: "At revision 1234"</p>
  
  <p>What is going wrong??</p>
