Problem

I am developing one eclipse osgi bundle to correct java source code automatically. I am able to get java project object and a class object inside it which I want to correct. I put one test file in project which can be corrected (like duplicate imports) but I receive below error on my code

Error

[color=red]
java.lang.IllegalStateException: Workbench has not been created yet.

Below is my code snippet:

....
CompletionProposalCollector collectorPrjTemp= new CompletionProposalCollector(javaProject); // this line throws error
IJavaCompletionProposal[] prjProposals = collectorPrjTemp.getJavaCompletionProposals();
System.out.println("prjProposals == "+prjProposals.length);
....

I though people would solve my problem here in minutes, but looks like this is really complex for them and I got no answer in this much time Sad

I need to create one handler from where I get ExecutionEvent Object and then I trigger my flow from that point and get object of Workbench, ResourcePlugin, Workspace and Project/JavaProject.

And at last I am able to get proposals which I need. So if you need workbench object you need UI.

If some one need more information he can contact me at shailendravermag@gmail.com
