Dagger 2: error: [ComponentProcessor:MiscError] circular dependency with generated code

Question

我正在做一个项目，旧匕首是在代码库中实现的。今天，我尝试将 dagger 实现优化到 dagger 2.2。如您所知，google 更新了 Dagger 库，使库易于在 android 中实现，有一些帮助程序类，如 Dagger Activity、Dagger 应用程序和 Dagger 片段类.

我已经更新了库，但我卡在了

的错误上

 error: [ComponentProcessor:MiscError]
 dagger.internal.codegen.ComponentProcessor was unable to process this
 interface because not all of its dependencies could be resolved. Check
 for compilation errors or a circular dependency with generated code.
 public abstract interface NewAppComponent extends
 dagger.android.AndroidInjector<com.mallconnect.tdm.TDMApplication> {

NewAppComponent

@Singleton
@Component(modules = [AndroidSupportInjectionModule::class,
            ActivityBuilderModule::class,
            AppModule::class,
            RoomModule::class,
            RetrofitModule::class,
            MappedInModule::class,
            ViewModelFactoryModule::class
])
interface NewAppComponent : AndroidInjector<TDMApplication> {

    /**
     * Session manager can be access any where in the application
     */
    fun sessionManager(): SessionManager

    @Component.Builder
    interface Builder {

        /**
         * [BindsInstance] annotation is used for, if you want to bind particular object or instance
         * of an object through the time of component construction
         *
         * @param application The application instance
         *
         * @return The Builder
         */
        @BindsInstance
        fun application(application: Application): Builder


        /**
         *
         * @return the AppComponent
         */
        fun build(): NewAppComponent

    }

}

ActivityBuilderModule

@Module
public abstract class ActivityBuilderModule {

    @ContributesAndroidInjector(modules = {MainFragmentBuildersModule.class,
            MainViewModelsModule.class})
    abstract Main contributeMainActivity();

    @ContributesAndroidInjector(modules = {AuthViewModel.class})
    abstract BaseActivity contributeBaseActivity();



}

我查了一些 Whosebug post 但我还没有找到解决方案

Dagger2 Circular Dependency Error

Dagger 2.15: Appcomponent - was unable to process this interface

我们如何追踪错误的根源？

Answer 1

我已经解决了评论中建议的循环依赖问题

The issue can't be addressed without going through all the modules that have been included in the component!

当我错误地通过 ActivityBuilderModule 时，我提供了 AuthViewModel 而不是 AuthViewModelModule 并且在 MainFragmentBuilderModule 内部我也证明了 ViewModel 而不是ViewModelModule 在 ContributeAndroidInjector

Answer 2

对我来说，这是因为我有一个数据 class，其中未指定顶部的包名称，因此，当导入此数据 class 时，它正在导入作为 import DataClassName 而不是完整的 class 化名，因此，它导致了循环依赖性
