Ian Williams added a comment - 2021-07-26 03:32 What version did you upgrade from, < 2.277.1 ? I would suspect this is a tables-to-divs issue, probably solved by updating plugins , or an incompatible plugin . Please provide the list of plugins installed on your system as suggested at "How to report a bug". Please confirm that you followed the instructions in the Jenkins 2.277.1 upgrade guide, especially that you updated your plugins after installing Jenkins 2.277.1. If you did not upgrade your plugins, please do so, then report if the issue remains.

Ian Williams added a comment - 2021-07-30 05:52 I'm going to take a guess and say this is likely related to at least tfs-plugin (presence of: "hudson.plugins.git.browser.TFS2013GitRepositoryBrowser")

Jessy Rodrigue added a comment - 2021-07-30 13:31 - edited Hi ianw We are also facing this same issue in our instance of Jenkins. We are not using the "tfs-plugin" and all plugins installed are up-to-date. Our instance of Jenkins was fairly new and trying to Downgrade kind of corrupted our Jenkins instance, so we created a new one (not much to loose for us at least). It's still not possible to add Credentials even after a clean install and using (mostly) default plugins. Is there a list of incompatible plugins where we could check if any one of them is installed on our instance? I provided you the list of all plugins installed on our Jenkins instance, see below.   Let me know if I can help with anything or if there's a solution to this.

Ian Williams added a comment - 2021-07-30 22:21 (I am just another user) The necessary information was provided in the earlier response. Table to div layout migration describes the problem and how to triage. JENKINS-64072 - Configure UI completely broken after upgrade to 2.264 is the originally JIRA tracking ticket for the issue. The list of incompatible plugins via: Tables to Divs Dashboard ; it may be incomplete but lists all issues tagged tables to divs regression. As is pointed out in all these type issues by markewaite , You need to follow the instructions in the upgrade guides between Jenkins (your version below 2.777.1 and latest. Those upgrade guides are available at Upgrade Guide . The Jenkins 2.277.1 upgrade guide is especially important to follow at Upgrading to Jenkins 2.277.1 because it will guide you to upgrade to current versions of all plugins, remove plugins with security warnings, remove deprecated plugins, and remove unused plugins. Refer to Table to Div Migration - Debugging for instructions to diagnose that type of message. The general pattern includes: Update plugins to their latest releases Remove plugins with security issues (like the TFS plugin) Remove plugins that are deprecated (like checkstyle, warnings, etc.) Remove unused plugins Compare your list of plugins with the plugins known to have issues with tables to divs. Remove or disable plugins with known issues Selectively disable plugins until you locate the plugin that is causing the issue. Report an issue for that plugin   Probably repeating myself there, but every installation is different, so it's up to the user to help triage and get the complete details right.

Mark Waite added a comment - 2021-07-31 01:16 - edited sujanreddy_bonga the message likely means that there are other messages earlier in the process that you did not mention. In this case, there is probably a message that says "Git plugin failed to load". That message is preceded by an explanation that will tell you why the git plugin failed to load. Usually it is because one of the dependencies of the git plugin failed to load. It might also be that you're trying to run with a Java version that is not supported by the Jenkins project. We support Java 8 and Java 11. Later versions of Java are not tested and are expected to fail. jessyrbwt it is highly unlikely that you're seeing the same problem as has been described by sujanreddy_bonga . Can you confirm that you are seeing a failure to add credentials or view existing credentials and that you're seeing a message about Java classes from the git plugin not being defined?

Mark Waite added a comment - 2021-07-31 01:26 jessyrbwt I placed your list of plugins as plugins.txt and used them to create a new installation of Jenkins 2.289.2 using the following commands: $ mkdir plugins $ java -jar ../jenkins-plugin-manager-2.10.0.jar --jenkins-version 2.289.2 --latest false --plugin-download-directory plugins --plugin-file plugins.txt $ JENKINS_HOME=. java -jar ../jenkins-2.289.2.war After doing that, I was able to create a new credential and update that credential.

Jessy Rodrigue added a comment - 2021-08-02 13:51 ianw  Thank you for the details, I'll try to find out what's going on with our Jenkins! markewaite You are right, my issue is not  quite the same. I'm not able to add credentials in the Pipeline (but it works in Jenkins Settings). I'll look more into it, try to run a new instance locally to test things out. Thank you for the tip with plugins.txt. I'm sure this will help me reproduce this issue!
