Issue

• JDK Installer for java.sun.com displays a text field instead of a dropdown list
• Cannot use JDK Installer

Environment

• CloudBees Jenkins Enterprise

Root cause

This is a problems of the basic function of the update center. The update center does not fetch the latest data file for the JDK Installer.

Resolution

This can be fixed inside a running instance of CJE.

Delete the failing JDK installers

1. Got to Manage Jenkins/Configure System
2. Remove the JDK installer
   

Force Jenkins to update the JDK Installer data file:

1. Go to Manage Jenkins/Script Console
2. Copy/Paste and Run this groovy script that will update the data file for tools and installers:

    hudson.model.DownloadService.signatureCheck = false
    hudson.model.DownloadService.Downloadable.get("hudson.tools.JDKInstaller").updateNow()
    hudson.model.DownloadService.signatureCheck = true
    return
   

3. The script might take few seconds to finish. A label Result appears below the Text Area indicating that the script has run.
   

   This line should appears in the log as well:

   ...
   INFO: Obtained the updated data file for hudson.tools.JDKInstaller
   ...
   

4. Go to Manage Jenkins/Configure System

5. Add a JDK Installation and select the java.sun.com JDK Installer. There should be a dropdown list.
