Я знаю, что есть несколько вопросов QnA по этому вопросу. Я пробовал много решений, я всегда получаю такую же ошибку.Загрузить экземпляр экземпляра EMF из файла XMI
Моя структура кода, как:
Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
Map<String, Object> m = reg.getExtensionToFactoryMap();
m.put("xmi", new XMIResourceFactoryImpl());
ResourceSet resSet = new ResourceSetImpl();
Resource resource = resSet.getResource(URI.createURI("model/List.xmi"), true);
resource.load(Collections.EMPTY_MAP);
EObject root = resource.getContents().get(0);
Ошибка:
Exception in thread "main" org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'List' not found.

Что значит 'пакет с URI "" не найден' означает? Могу ли я прочитать файл xmi напрямую или мне нужно проанализировать его как XML-файл?
Я также попытался это ->https://stackoverflow.com/a/4615965/1604503
XMIResource resource = new XMIResourceImpl(URI.createURI("model/List.xmi"));
resource.load(null);
System.out.println(resource.getContents().get(0));
PackageNotFoundEx. и Reource $ IOWrappedEx. опять :(
Пожалуйста, помогите
