I am working on reusing Eclipse JDT inline method refactoring and I need to access the workspace so I can get the ICompilationUnit [ please do correct me if I am wrong about this information ]:
IWorkspace workspace = ResourcesPlugin.getWorkspace();
Since the ICompilationUnit is requiered here:
InlineMethodRefactoring refactoring = InlineMethodRefactoring.create(icu,new RefactoringASTParser(ASTProvider.SHARED_AST_LEVEL).parse(icu, true), selection[0], selection[1]);
So I have read that accessing the workspace requires building either an Eclipse plug-in or a headless RCP .. so I created a headless RCP application following this tutorial as I do not need the UI to start up. Now everything works fine and the refactoring is applied but the following exceptions are printed in console - such as:

- Maybe I should configure the application to run with only a set of plug-ins instead of including them all? [ do not know what to include or exclude] Click to see the configuration
- Is there any other way for me to get the
ICompilationUnitwithout accessing the workspace? - Is there any simpler way to use all JDT features in, for example, a simple maven project instead of an Eclipse plug-in or an RCP application?
- Any tutorials on RCP development from within Eclipse is much appreciated.
Thanks.
