git - Jenkins GitHub plugin can't choose my credentials

Question

I got very strange behavior that has never happened before, when I try to configure the GitHub server in Jenkins general configuration to set up webhooks auto.

The drop down menu doesn't display my registered credentials. I was always be able to do that, but suddenly I don't know what's happening. I tried to uninstall the plugin, restarting Jenkins, kill the Jenkins Docker container and configure all the stuff again ... still I got the same issue.

There is no other option other than none, and when I add new credentials I still get None as the only option...

Answer 1

The issue is that the GitHub plugin only accepts plain text credentials.

The GitHub access token can be created manually, or automatically via the Advanced... options as described here.

In case you already have an access token in GitHub (you'll get an error in Jenkins), you can remove it in Github. Then you can let Jenkins generate the token and select it in the Credentials menu.
