title: Incompatible groovy compiler version
body: <p>I have grails-2.2.0 installed on Mac OS X 10.8.2 (Mountain Lion) and I am using Groovy-Grails-Tool-Suite with grails and Java installed correctly. However, when I create a new Grails Project, I get a message saying - </p>
  
  <pre><code>Some projects in your workspace use Grails 2.20 
  
  You are using the Groovy 1.8.6.xx-20120921-2000-e43RELEASE compiler.
  
  Grails requires version range 2.0.0
  
  Various functionality may break if you use an incompatible compiler.
  
  Set Preferences &gt;&gt; Groovy &gt;&gt; Compiler to change the compiler version.
  </code></pre>
  
  <p>Has anyone else encountered this. I am using GGTS based on Eclipse 4.2 (Juno)</p>
