Bug 102285 [Import/Export] Project Import wizard unusably slow
R3.1 I wanted to create a new 3.2 workspace and import some projects from my 3.1 development workspace which contains around 120 plug-ins. I've set the root of the importer to point at those plug-ins. After letting the wizard scan my disk for over 10 minutes I gave up and did it manually. A possible source for the problem might be that the root directory (as expected) contains a .metadata directory with tons of data (in my case) and that this one is fully scanned.

selectedProjects[index] = new ProjectRecord(file);
							index++;
						}
					} else
						monitor.worked(60);
					monitor.done();
				}
			});
		} catch (InvocationTargetException e) {
			IDEWorkbenchPlugin.log(e.getMessage(), e);
		} catch (InterruptedException e) {
			
		}
		projectsList.refresh(true);
		projectsList.setCheckedElements(selectedProjects);
		setPageComplete(selectedProjects.length > 0);
