Downgrade Jenkins
I have been struggling with downgrading Jenkins as well, lately because the latest version seems to have a problem handling JDK 5 code (which I am unfortunately tied to for a little while longer)
Here's how I did my downgrade:
- Locate an earlier stable version at https://updates.jenkins-ci.org/
- Download the war file
- Stop the Jenkins service
- Replace the
jenkins.warwith the new. - Restart the service.
I had an additional issue with the configuration file not being compatible. E.g. In my case I had to disable matrix to get the service running. Your case may be different, so I suggest another question.
Downgrading should be equivalent to the upgrading process:
To upgrade from earlier versions of Jenkins, simply redeploy the WAR file. Read this document for more about container-specific instructions on how to do this. See this document for automation.
