I just configured my first slave (Ubuntu) and I am having the same issue listed here: https://issues.jenkins-ci.org/browse/JENKINS-19435
I am running Jenkins ver. 1.546 (master), ssh-slaves (tried both 0.25 and 1.5), credentials 1.9.4, ssh-agent 1.4.1, ssh-credentials 1.6. I have tried it both with the full path to the key as well as cut/paste. hudson.AbortException: Cannot find SSH User credentials with id: 284bb56c-625c-48cf-89a2-7d85d1a6d4d1 at hudson.plugins.sshslaves.SSHLauncher.openConnection(SSHLauncher.java:915) at hudson.plugins.sshslaves.SSHLauncher.launch(SSHLauncher.java:479) at hudson.slaves.SlaveComputer$1.call(SlaveComputer.java:228) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) [01/06/14 15:01:09] [SSH] Connection closed. Any ideas? Thanks, Ci-Ci -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
