title: Grails run-app 'Application metadata not found'
body: <p>I downloaded a serverpush example called GrailsChat and trying to run is on grails 2.4.4.</p>
  
  <p>I had some issues with dependencies missing that took me a while to figure out (don't think it's related but just mentioning it).</p>
  
  <p>When I run grails run-app I get:</p>
  
  <pre><code> | Application metadata not found, please run: grails upgrade
  </code></pre>
  
  <p>When I run grails upgrade I get </p>
  
  <pre><code> | Script 'Upgrade' not found, did you mean:
  1) MigrateDocs
  2) IntegrateWith
  3) SetGrailsVersion
  4) InstallDependency
  5) DependencyReport
  
  &gt; Please make a selection or enter Q to quit:     
  </code></pre>
  
  <p>I figure the issue is probably to do with the grails version I have being newer than the grails version that the sample app was targetting but I don't want to move back version simply to run an example (I'd rather understand the underlying issue).</p>
  
  <p>Can anyone point me to some documentation that will help me understand what the application metadata is and how to move forward please?</p>
