How do I initiate a puppet run from Jenkins?

[lfast]

I'm getting lost in the number of different ways to integration Jenkins & Puppet.  What I'm looking for should be simple:  From Jenkins, execute puppet agent/apply on a remote server. 

I'm currently using the SSH plugin to run puppet on the remote server.  I'm just starting to look at the Workflow system but as yet haven't found the syntax for using the SSH plugin in a Workflow or anything equivalent.

I also recognize that the core issue here is managing authentication onto the remote server.  Are there any 'best practices' for this?  General recommendations or even 'this worked for me' would also make me happy.

I tried the following:
node {
 step([$class: 'org.jvnet.hudson.plugins.SSHBuilder',
       siteName: 'me@myserver:22',
       command: 'echo hello myserver|tee testJenkins'
      ])
}
But if I'm guessing right, this plugin requires an update to be compatible with Workflow.  Here's the error I get.

java.lang.ClassCastException: class org.jvnet.hudson.plugins.SSHBuilder
	at java.lang.Class.asSubclass(Class.java:3037)
	at org.jenkinsci.plugins.workflow.structs.DescribableHelper.coerce(DescribableHelper.java:183)

You can use something like this:

This mechanism help you do any ssh related task. Where 'ssh_key_file' is secrete file base credentials.

def runShellwithCredentials(ssh_key_file,cmd) {
  env.RUN_CMD = cmd
  try {  
    withCredentials([[$class: 'FileBinding', variable: 'PVT_KEY_FILE', credentialsId: ssh_key_file]]) {
      sh '''
        chmod 0500 $PVT_KEY_FILE
        env 
        eval `ssh-agent`
        ssh-add $PVT_KEY_FILE
        $RUN_CMD
        kill -s term $SSH_AGENT_PID
      '''
    }
  } catch (e) {
    def w = e.printStackTrace()
    mailSubject += " has failed with ${e.message}"
    mailBody    += mailSubject
    mailer(mailSubject,mailBody)
    throw e
  }
}

Hi,

Is your code Java-Code? Why using Java in puppet?
