CoroutineDispatcher 注入时 Hilt 构建失败

Question

不确定为什么构建失败。一切似乎都在受控之中

class MapObjectRepositoryIMPL @Inject constructor(\n    @ApplicationContext context : Context,\n    val mapObjectDao: MapObjectDao,\n    val barrechatNetwork: BarreNetwork,\n    @DefaultDispatcher private val defaultScope: CoroutineContext\n) : MapObjectRepository {\n\n

@Module\n@InstallIn(ApplicationComponent::class)\nobject DispatcherModule {\n\n    @DefaultDispatcher\n    @Provides\n    fun providesDefaultDispatcher(): CoroutineDispatcher = Dispatchers.Default\n\n    @IoDispatcher\n    @Provides\n    fun providesIoDispatcher(): CoroutineDispatcher = Dispatchers.IO\n\n    @MainDispatcher\n    @Provides\n    fun providesMainDispatcher(): CoroutineDispatcher = Dispatchers.Main\n}\n\n@Qualifier\n@Retention(AnnotationRetention.BINARY)\nannotation class IoDispatcher\n\n@Qualifier\n@Retention(AnnotationRetention.BINARY)\nannotation class MainDispatcher\n\n@Qualifier\n@Retention(AnnotationRetention.BINARY)\nannotation class DefaultDispatcher\n

我收到的错误是这样的，但看起来我正确提供了所有内容，限定符和对存储库类的注入，这很奇怪......

我刚刚对此进行了测试，问题出在这一行：

@DefaultDispatcher private val defaultScope: CoroutineContext

CoroutineContext将type替换为CoroutineDispatcher，它将按预期工作。
