title: Eclipse Groovy and autocompletion
body: <p>I am using the current version of SpringSource Tool Suite with the Groovy/Grails plugin installed. I can understand that when defining and using "pure" groovy classes/objects there are cases that make code autocompletion difficult.</p>
  
  <p>But if I use Java classes in the groovy class shouldn't the autocompletion feature work as intended? For example i'm trying to use "readFileToString" from the org.apache.commons.io.FileUtils class. Eclipse only suggests groovy methods for this class, there is no static method in the list from FileUtils class.</p>
  
  <p>Is it a problem with my installation of STS or maybe the groovy editor in STS just doesn't support autocompletion for pure java classes?</p>
