Description Sasmita Acharya CLA 2017-04-17 10:40:14 EDT 
Steps:
1. Create a Java project with a class having main method.
2. Create a Launch configuration with a shared file(common tab)
3. Run the project and make sure the launch file created in shared file location.
4. Rename the project(with F2)
5. Select Edit>Undo Rename Java Project
6. Select Edit>Redo Rename Java Project > Shows up a error dialog with as below:

'Rename Resource' cannot be redone. 
Reason: The launch configuration "<projectName>" no longer exists.

Upon debug: found that isValid of LaunchConfigurationProjectMainTypeChange, pointing to non-existing Location of Project which has already been moved to new name(redo name). 

I think the project should not been moved before validating the launch config.

You have specified 4.5 as the version - it is not supported anymore. Can you please check if this is still on 4.6.3 or 4.7 M6? Do you want to provide a patch?
Comment 2 Sarika Sinha CLA 2017-04-21 02:04:31 EDT 
I can reproduce this in latest 4.7 build as well.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
