title: Installing Groovy 1.8 on Spring Tool Suite 3.6.1
body: <p>I have <em>Spring Tool Suite 3.6.1</em>, which is based on <em>Eclipse 4.4.</em></p>
  
  <p>I installed the version of <em>Grails</em> I need, but I noticed that the <em>Groovy</em> compiler is at 2.3, whereas I need it to be at 1.8.</p>
  
  <p>I've gone to <code>dist.springsource.org</code> on the <em>Eclipse Marketplace</em> to look for the Compiler 1.8. I can install it, but it automatically uninstalls the existing <em>Grails IDE</em>. On top of that, it doesn't appear under <code>Preferences - Groovy - Compiler</code> and I don't seem to be able to select it.</p>
  
  <p><em>What am I doing wrong? Do I need to use an earlier version of the Spring Tool Suite to access this particular compiler?</em></p>
