未生成Android Kotlin Dagger 2组件

Question

I have no Idea why my DaggerComponent is not generated after rebuild the project.

@Scope
@Retention(AnnotationRetention.RUNTIME)
annotation class NewsScope

---

@NewsScope
@Component(
    dependencies = [BaseComponent::class],
    modules = [NewsModule::class]
)
interface NewsComponent {
    fun newsManager(): NewsManager
}

---

@NewsScope
@Component(
    dependencies = [BaseComponent::class],
    modules = [NewsModule::class]
)
interface NewsComponent {
    fun newsManager(): NewsManager
}

---

@Module
class NewsModule {

    @NewsScope
    @Provides
    fun provideMoshiConverterFactory(): MoshiConverterFactory {
        val moshi = Moshi.Builder().build()
        return MoshiConverterFactory.create(moshi)
    }

    @NewsScope
    @Provides
    fun provideNewsApi(okHttpClient: OkHttpClient): NewsApi {
        val moshi = Moshi.Builder().build()

        val retrofit = Retrofit.Builder()
            .client(okHttpClient)
            .baseUrl(NewsApi.API_URL)
            .addCallAdapterFactory(RxJavaCallAdapterFactory
                .createWithScheduler(Schedulers.io()))
            .addConverterFactory(MoshiConverterFactory.create(moshi))
            .build()

        val retrofitApi = retrofit.create(RetrofitNewsApi::class.java)

        return RetrofitNewsApiImpl(retrofitApi)
    }

    @NewsScope
    @Provides
    fun provideNewsManager(newsApi: NewsApi): NewsManager {
        return NewsManager(newsApi)
    }
}

class NewsFragment : BaseFragment() {
    @Inject lateinit var newsManager: NewsManager private set


    override fun onCreate(savedInstanceState: Bundle?) {
        newsManager = DaggerNewsComponent.builder() 
            .baseComponent(baseComponent())
            .newsModule(NewsModule())
            .build().newsManager()
    }
}

• *** DaggerNewsComponent not Generated
• $dagger_version = "2.23.2"
• AndroidX was implemented

• I am a iOS Pro but Android Noob

  implementation "com.google.dagger:dagger:$dagger_version" implementation "com.google.dagger:dagger-android:$dagger_version" implementation "com.google.dagger:dagger-android-support:$dagger_version"

  annotationProcessor "com.google.dagger:dagger-android- processor:$dagger_version" annotationProcessor "com.google.dagger:dagger-compiler:$dagger_version"

Answer 1

You should use kapt next to annotationProcessor

kapt 'com.google.dagger:dagger-android-processor:2.23.2'
kapt 'com.google.dagger:dagger-compiler:2.23.2'

and add apply plugin: 'kotlin-kapt' at top of your build.gradle

Answer 2

Yes and also add

android {
    kapt {
        generateStubs = true
    }
}
