title: Jenkins Parameterized Remote Trigger Plugin to return build number
body: <p>I am using Jenkins with the Parameterized Remote Trigger Plugin. Once I kick off a remote build I would immediately like to get the build number of that remote job. </p>
  
  <p>If I inspect the console output of the remote job that is running I can see "This job is build #[1234] on the remote server."</p>
  
  <p>Is there a way of grabbing that job number? I don't want to wait until job completion to get the information.</p>
