Jenkins 1.599 oracle JDK no longer populates a drop down list

[Sean Last]

And it throws an error about not having any data if you try and build with a new java version.  

Anyone seen this?  Any ideas?

It may be best to ask questions about compiling Jenkins with a specific JDK on the jenkins-dev mailing list.

There were issues in the past when compiling with Java 8.  I believe the shipped Jenkins compiles with Java 7.

not compiling jenkins.  Getting jenkins to download the JDK from oracle.  However, it appears that even though I can ping and wget from all appropriate servers on this vagrant image, jenkins itself can't reach out for some reason  Which is weird, because I've never had a problem before.

Might be worth sharing the error you are seeing as its hard to diagnose in the dark :)

We use version 1.594 and have the same problem. I attached a screenshot.

The JDKs that were already configured to download from java.sun now all have the same 'JDK ID': jdk-8u40-oth-JPR (see attached screenshot)

Go to Manage Jenkins » Manage Plugins » Advanced and click 'Check Now'.

If that doesn't help, check the log at /log/all for possibly relevant messages.

Are you in China or a neighboring country?

clicking on 'Check Now' didn't help and we are located in Germany.

As Jenkins is started with '--logfile=/home/jenkins/logs/jenkins.log' you mean this logfile? Nothing relevant in there.

I downloaded jenkins-1.594.war and started it locally. The drop-down was populated with all JDKs.

I found this issue: https://issues.jenkins-ci.org/browse/JENKINS-10176

So I checked that http://jenkins.mirror.isppower.de/updates/updates/hudson.tools.JDKInstaller.json?version=1.594 works.

Then I looked at the file 'hudson.tools.JDKInstaller' that was mentioned in the issue. The contents was exactly the same as the file 'hudson.tasks.Maven.MavenInstaller' which is very strange but could be the reason for the error.

I deleted 'hudson.tools.JDKInstaller' hoping that it would be downloaded again. But nothing happend.

Fixed in 1.596 with server-based download.

The easiest solution is to restart Jenkins to force a redownload.

[Clifford Sanders]

Updating or restarting can't be done during office hours.

I solved it by copying the file 'hudson.tools.JDKInstaller' from my local Jenkins to the 'updates' directory on the remote Jenkins.

Is there a Jira issue for the fix in 1.596? The original poster wrote that the error still occures in 1.599.

I got the versions wrong, it's 1.596.1 (LT)S and 1.600 that are fixed. They require the administrator to disable browser-based downloads in the security preferences.

The fix is for SECURITY-163, described at https://wiki.jenkins-ci.org/display/SECURITY/Jenkins+Security+Advisory+2015-02-27, and it is thought to fix this reliability issue as well.

Thanks Daniel. I also found this related Jira isuue:

"Auto-installer for JDK no longer works": https://issues.jenkins-ci.org/browse/JENKINS-26780

Right, it contains a bit of background info. Note that that was before the version that now defaults to server-based download came out. Now I recommend using server-based downloads in general.
