title: Grails - How to change project's Grails version in Spring Tool Suite 3.5.1
body: <p>In Spring Tool Suite 3.5.1.Release , how do I set a project-specific Grails version?</p>
  
  <p>I have multiple versions of Grails configured in STS. </p>
  
  <p>Older versions of STS had a section called Grails in the "Properties for <em>project</em>" window where a particular version of Grails could be selected. </p>
  
  <p>After upgrading to 3.5.1.Release I no longer see this option.</p>
  
  <p>Thanks!</p>
