title: Jenkins: cannot automatically install gradle. No version list from Gradle.org
body: <p>in Jenkins, I have always used the option to install Gradle automatically from the Gradle.org server (Manage Jenkins -> Configure System -> Gradle Installations.</p>
  
  <p>Now I have set up a new Jenkins installation on an Ubuntu 14 System.
  I installed the Gradle plugin, but now, when I choose "Install automatically" in the Gradle configuration, I am not able to choose the Gradle version that should be downloaded. Usually you get a select box with all available Gradle versions, but in my case, I only get an empty text field under "Install from Gradle.org".</p>
  
  <p>Please see the screenshot
