Dagger 2无法访问Retrofit

Question

我正在尝试使用Dagger 2(使用Android模块)向我的存储库提供一个Retrofit实例.买我面临错误:

错误:无法访问Retrofit

像毕加索这样的其他实例注入成功,我只是在改造时遇到了问题.

我的模块

@Module
class NetworkModule {

@Provides
@Singleton
fun providesRetrofit(): Retrofit {
    return Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create())
            .baseUrl(URL_BASE)
            .build()
}

@Provides
@Singleton
fun providesPicasso(context: Context): Picasso {
    return Picasso.Builder(context)
            .loggingEnabled(true)
            .build()
}

@Provides
@Singleton
fun providesRemoteRepository(retrofit: Retrofit): RemoteRepository = RemoteRepository(retrofit)

@Provides
@Singleton
fun providesRepository(remote: RemoteRepository): Repository = RepositoryImp(remote)

}

我的应用程序组件

@Singleton
@Component(modules = arrayOf(
        AppModule::class, NetworkModule::class, AndroidInjectionModule::class, ActivityBuilder::class
))
interface AppComponent {

    @Component.Builder
    interface Builder {

        @BindsInstance
        fun application(app: Application): Builder

        fun build(): AppComponent

    }

    fun inject(application: AppApplication)

}

应用组件

@Module
class AppModule {

    @Provides
    @Singleton
    fun providesApplicationContext(app: Application): Context = app

}

活动构建器

@Module
abstract class ActivityBuilder {

    @ContributesAndroidInjector(modules = arrayOf(MainActivityModule::class))
    abstract fun bindMainActivity(): MainActivity

}

我的资料库'

class RepositoryImp @Inject constructor(val remoteRepository: RemoteRepository) : Repository {

    override fun fetchData() {

    }

}

我的远程存储库

class RemoteRepository @Inject constructor(retrofit: Retrofit) {

    val service: ApiService

    init {
        service = retrofit.create(ApiService::class.java)
    }

}

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:kaptDebugKotlin'.
> Internal compiler error. See log for more details

谢谢!

我发现了问题,在build.gradle中...我的改造实例是在一个单独的模块中.这个模块是一个api:

App build.gradle

api project(':data')

我在改造依赖项中使用了实现.我改为api,问题得到解决.

api "com.squareup.retrofit2:retrofit:$retrofit_version"
api "com.squareup.retrofit2:converter-gson:$retrofit_version"
