Bug 44162 [Wizards] Define constants for wizard ids of new.file, new.folder, and new.project
In perspective factories, plugins have to reference the New wizards with a string that is susceptible to change during API reorganizations. For example, in org.eclipse.ui.internal.ResourcePerspective: // Add "new wizards". layout.addNewWizardShortcut("org.eclipse.ui.wizards.new.folder");//$NON-NLS-1$ layout.addNewWizardShortcut("org.eclipse.ui.wizards.new.file");//$NON-NLS-1$ There are constants for most view id's, for example IPageLayout.ID_RES_NAV, but not for these. This request is to add constants for the new wizard ids in the appropriate location. In addition to new.folder and new.file above, you also need a constant for new.project. There may be others but those are the only ones I found in a search.

.newProjectDescription(newProjectHandle.getName());
		description.setLocationURI(location);
		
		if (referencePage != null) {
			IProject[] refProjects = referencePage.getReferencedProjects();
			if (refProjects.length > 0) {
				description.setReferencedProjects(refProjects);
			}
		}
		
		IRunnableWithProgress op = new IRunnableWithProgress() {
			public void run(IProgressMonitor monitor)
					throws InvocationTargetException {
				CreateProjectOperation op = new CreateProjectOperation(
						description, ResourceMessages.NewProject_windowTitle);
				try {
					PlatformUI.getWorkbench().getOperationSupport()
							.getOperationHistory().execute(
									op,
									monitor,
									WorkspaceUndoUtil
											.getUIInfoAdapter(getShell()));
				} catch (ExecutionException e) {
					throw new InvocationTargetException(e);
				}
			}
		};
		
		try {
			getContainer().run(true, true, op);
