title: auto completion on generated java code in eclipse
body: <p>I would like to make auto generated code available to eclipse editor for auto completion</p>
  
  <p>Following cases:</p>
  
  <p>1) Xml document describing a data model and java processor is creating java source code.
    Right now I need to run ant script to create java source.
    Could that be triggered by change of xml document?</p>
  
  <p>2) Class is extended with new methods by apt processor.
    Is it possible to register apt processors to the jdt?</p>
  
  <p>3) Instrumented java byte code creates new methods.
    Is it possible to make the auto completion read through a class loader which is doing byte code weaving? </p>
