android - 我收到 'circular dependency' Android Dagger Hilt 错误

Question

我从头开始检查了所有内容，但找不到错误。我找不到错误，可能是什么？
我收到以下编译错误；

HomeViewModel.java:6: error: [ComponentProcessor:MiscError] dagger.internal.codegen.ComponentProcessor was unable to process this class because not all of its dependencies could be resolved. Check for compilation errors or a circular dependency with generated code.
public final class HomeViewModel extends androidx.lifecycle.ViewModel {

Answer 1

您需要添加@HiltViewModel在您的 vm 中，如果您使用 hilt vm factory 在您的 Activity/fragment 中注入(inject) vm。
此外，您可以绑定(bind)您的 MoviesRepositoryImpl与 MoviesRepository您已经在为 MoviesRepositoryImpl 使用构造函数注入(inject)，而不是为其编写提供程序。
怎么样 -

@Module
@InstallIn(SingletonComponent::class)
interface MoviesRepositoryImplModule {
    @Binds
    fun bindMoviesRepositoryImpl(movieRepoImp: MoviesRepositoryImpl): MoviesRepository
}

并删除

    @Provides
    @Singleton
    fun provideMoviesRepository(movieService: MovieService): MoviesRepository = MoviesRepositoryImpl(movieService)
