Я прочитал документацию об использовании Dagger Hilt для внедрения ViewModels. Я пытался реализовать в своем приложении, но при сборке Gradle постоянно получаю сообщение об ошибке, и проект не компилируется. Как я могу исправить эту проблему?
/home/amcap1712/Documents/MusicBrainzAndroid/app/src/main/java/org/metabrainz/mobile/presentation/features/artist/ArtistViewModel.java:19: error: [Hilt]
public class ArtistViewModel extends LookupViewModel {
^
org.metabrainz.mobile.presentation.features.artist.ArtistViewModel, expected to be annotated with @DefineComponent. Found:
[Hilt] Processing did not complete. See error above for details.warning: File for type 'org.metabrainz.mobile.App_HiltComponents' created in the last round will not be subject to annotation processing.

ArtistViewModel.java Этот класс расширяет другой абстрактный класс LookupViewModel, который я создал, с помощью некоторых общих функций, которые я использую во многих моделях просмотра.
....
public class ArtistViewModel extends LookupViewModel {
....
@ViewModelInject
public ArtistViewModel(LookupRepository repository) {
super(repository);
.....
}
....
LookupRepositor.java
....
@Module
@InstallIn(ArtistViewModel.class)
public class LookupRepository {
private static LookupRepository repository;
private LookupRepository() {
}
@Singleton
@Provides
public static LookupRepository getRepository() {
if (repository == null) repository = new LookupRepository();
return repository;
}
....
