				destinationPath = destination;
			} else {
				destinationPath = destination.append(source.getName());

			IWorkspaceRoot workspaceRoot = getWorkspaceRoot();
			IResource existing = workspaceRoot.findMember(destinationPath);

							new SubProgressMonitor(monitor, 1), uiInfo, false);
					
					
					for (int j = 0; j < overwritten.length; j++) {
						overwrittenResources.add(overwritten[j]);
