Duplicating a project

If necessary, you can save a copy of an existing project in the workspace under a different name. The duplicated project includes all files, folders and resources of the original project renamed accordingly.

To duplicate a project in the workspace:

Select the original project in the Project Explorer and press CTRL+C.
Press CTRL+V to paste the copied project to the workspace. Rename the duplicated project and click OK.

The new project appears in the Project Explorer with the “warning” sign over the root folder. The Problems view reports about launch configuration names mismatching the name of the duplicated project.
Right-click any configuration warning and click Quick Fix on the context menu.
Select all broken launch files from the Problems list and click Finish to apply the "Fix to expected project name" fix.

Now the duplicated project does not show any warnings.
