Renaming private fields, methods, and all properties will not update references in non-working copies

• In Foo.groovy

  class Foo {
    def foo
  }
  

• In Other.groovy

  new Foo().foo
  

• Close and save Other.groovy
• Rename foo

Reference to foo in Other.groovy is not updated. This is because org.eclipse.jdt.internal.corext.refactoring.RefactoringScopeFactory.create(IJavaElement, boolean, boolean) ignores otehr compilation units if the target to rename if private (and in this case, foo is a property, so it is private).

Potential solution: in org.eclipse.jdt.core.search.SearchEngine.search(SearchPattern, SearchParticipant[], IJavaSearchScope, SearchRequestor, IProgressMonitor), add a hook into language support that will check the search pattern and requestor to see of the search scope should be expanded.

Here are the criteria for expanding the search scope:

1. pattern.focus is a private field or method in a groovy compilation unit
2. requestor is of type (or a subtype of) org.eclipse.jdt.internal.corext.refactoring.CollectingSearchRequestor.

If this matches, then create a search scope that encompasses the entire project and all depending projects.

This solution is more than a little ugly, but I don't see any other way of proceeding.
