Answer 1

I ran into a similar issue and how I fixed it was to add a cmdline switch when starting up jenkins. I set the (long winded) -Dorg...useCLI=true

nohup java -Dorg.jenkinsci.plugins.gitclient.Git.useCLI=true -jar jenkins.war > jenkins.log 2>&1 &

The gist of it is that this switch makes jenkins use installed git, not a JGit client.

Hope that helps.

Also, here's a URL to check out (especially long trail of comments)

Answer 2

I faced the similar issue after I changed the password of Remote Linux machine.

Updating Passphrase/Password in Credentials section of a Job as well as under Manage Jenkins -> Configure Sytem -> SSH remote hosts worked for me.

Answer 3

Ran into this today. I could ssh from within Jenkins to two systems but not the third, all with shared credentials. It turned out the /etc/ssh/sshd_config on the failing system had "PasswordAuthentication no". This caused the correctly reported Auth fail.
