title: Grails 3 Quartz plugin: Job doesn't start
body: <p>I am trying to do a simple background job in Grails. I just want stuff to happen every 30 seconds or so.</p>
  
  <p>I am using Grails 3.1.3</p>
  
  <p>I've added Quartz to my dependencies:
  compile "org.grails.plugins:quartz:2.0.1"</p>
  
  <p>Then I've run a compile and restarted the grails CLI. Now I created a Job via create-job. It looks like this:</p>
  
  <pre><code>package htwp
  
  class UserSyncJob {
      static triggers = {
        simple repeatInterval: 5000l // execute job once in 5 seconds
      }
  
      def execute() {
          println ("?")
          log.error("??!")
          throw new Error("JOB WHERE ARE YOU");
      }
  }
  </code></pre>
  
  <p>Nothing happens when I start the server via run-app. Nothing printed, no errors either. 
  What am I doing wrong?</p>
