title: GGTS 3.6 Groovy:Internal groovy compiler error
body: <p>I have a grails project, recently nothing compiles.
  in eclipse on the Problems tab I see 100 out of 300 problems, most of them are Groovy:Internal groovy compiler error. every class has a red X on it, if I add an empty line in the file and save it the error would go away but not for long.</p>
  
  <p>I had tried Build / Clean (both eclipse's and grails') / Refresh Dependencies / Compile in any possible combination. The run-app command works from eclipse with no issues. but eclipse is going crazy because I have so many errors. The only way I could make the errors go away is to disable eclipse's Build Automatically option and clean (without allowing it to build after) </p>
  
  <p>Does anyone has an Idea ?</p>
