    Description

      I keep running into this. It's not a consistent behavior as the same CLI command passes/fails randomly.

      The command from CLI is: java -jar jenkins-cli.jar -s http://my-URL build job_name --username "admn" --password "admn1234" -p p1=$var p2=$othervar -w

      And here's the obtained error:
      May 11, 2015 3:04:05 PM WARNING org.jenkinsci.main.modules.cli.auth.ssh.SshCliAuthenticator authenticate
      CLI authentication failure

          Does it fail randomly for the same user, on the same machine? As the error is in SSH Key authentication, it is dependent on your environment.

          Hi Daniel,
          It's the same user. Two machines submitting to the same master often fail.
          However, I spent some time looking at things yesterday, and I realized that even in the case where the CLI build submission is actually invoked, the log would still show:
          May 12, 2015 6:41:53 AM WARNING org.jenkinsci.main.modules.cli.auth.ssh.SshCliAuthenticator authenticate

          Any ideas?

          Try to add the -noKeyAuth option to the java -jar jenkins-cli.jar invocation.

          -noKeyAuth, can you explain a bit on what this option would do?
          Note that: the master is password-protected.

          It will prevent trying to authorize using an SSH key (e.g. ~/.ssh/id_rsa) which the CLI does by default.

          How will it handle the authorization then?
          Another thing, had this been always failing or passing, I wouldn't be this skeptical on this solution.
          The fact that it's an inconsistent/random/intermittent failure is the troubling part. Any ideas on what could be the reason?

          You're specifying user name and password on the command line.

          raccary So, did it work?

          It still shows in the logs as a warning.
