title: How can I ensure that only one if a kind of Jenkins job is run?
body: <p>I have several integration tests within my Jenkins jobs. They run on several application servers, and I want to make sure that only <strong>one</strong> integration test job is run at the same time on one application server.</p>
  
  <p>I would need something like a tag or variable within my jobs which create a group of jobs and then configure the logic that within that group, only one job may run at the same time.</p>
  
  <p>Could I use the Exclusion plugin for that? Does anyone have experience with it?</p>
