I’m encountering significant compatibility issues with several Jenkins plugins after updating Jenkins to the latest version, and I’m seeking assistance to resolve it.
Background: I recently updated my Jenkins instance to the latest version to take advantage of new features and security improvements. However, since the update, several of my previously functioning plugins are now causing build failures and generating errors.
Issue: The main problem arises when running build jobs that rely on specific plugins. After the Jenkins update, these plugins either fail to load correctly or produce errors during the build process. This has led to failed builds and disruptions in our continuous integration/continuous deployment (CI/CD) pipeline. Some of the errors include “Plugin not found,” “Incompatible plugin version,” and “Null pointer exception.”
Troubleshooting: Here are the steps I’ve taken to troubleshoot the issue so far:
Verified that all plugins are updated to their latest versions compatible with the new Jenkins release.
Reviewed the Jenkins logs and plugin error messages for specific details on what might be causing the failures.
Disabled and re-enabled the problematic plugins to see if it resolves the issue.
Attempted to roll back to previous versions of the plugins to restore functionality.
Checked the Jenkins and plugin documentation for any known compatibility issues or required configurations after an update.
Observations: Despite these efforts, the compatibility issues with the plugins persist, resulting in continuous build failures and impacting our development workflow. This problem is critical as it affects our ability to reliably execute and automate our CI/CD processes.
Request for Assistance: If anyone has experience with resolving plugin compatibility issues after a Jenkins update or has encountered similar problems, I would greatly appreciate your insights and assistance. Specifically, I’m looking for strategies to identify and fix the root causes of these plugin errors and ensure seamless integration with the updated Jenkins version.
There are a number of people on community.jenkins.io that are experienced with diagnosing those types of failures. They almost always need details that will help them as they try to help you resolve the issue. Some of the details that are needed include:
Detailed Jenkins, Java, and plugin versions
Provide the current Jenkins version, Java version, and the plugin names and versions that you’re using with that Jenkins version. There is a script that can be run in the Jenkins system console (“Manage Jenkins” >> “Script Console” ) to provide that information. That information is critical. Without it, they are limited to offering guesses based on your failure descriptions.
Detailed startup error messages
Provide the detailed error messages, especially from the Jenkins log file, including the stack traces that may be reported early in the startup process. This is less critical than the version information, but can make the diagnosis move much more quickly.
Detailed build failure error messages
Share one or more detailed error messages from build failures, including stack traces. This is less critical than the detailed error messages from startup, but can help identify later problems that the earlier steps might have missed.
Original Jenkins, Java, and plugin versions
Provide the original Jenkins version, Java version, and plugin versions that were working for you if you have them. Don’t worry too much if you don’t have all the details for this information. This is usually the least useful information, but may help others understand how large an upgrade you’ve performed. When upgrading across multiple years of releases and Java versions, there can be many different forms of surprises that were listed in the intervening changelogs and upgrade guides.
Despite updating all plugins to their latest versions compatible with the new Jenkins release, the issues persist. Disabling and re-enabling the problematic plugins, as well as attempting to roll back to previous versions, did not resolve the problems.
I appreciate any further assistance or insights you can provide to help identify and fix the root causes of these plugin compatibility issues.
