無法用匕首運行kotlin 2

我是kotlin和匕首的新手2.我嘗試在Android Java中關注此guide。但錯誤是拋出...無法用匕首運行kotlin 2

Error:Execution failed for task ':app:kaptDebugKotlin'. Internal compiler error. See log for more details

我做錯了什麼？

應用

class App : Application() { 

    val netComponent: NetComponent by lazy { 
     DaggerNetComponent.builder() 
       .appModule(AppModule(this)) // This also corresponds to the name of your module: %component_name%Module 
       .netModule(NetModule("https://api.github.com")) 
       .build() 
    } 

    override fun onCreate() { 
     super.onCreate() 
    } 

    fun netComponent() : NetComponent = netComponent 
}

NetComponent

@Singleton 
@Component(modules= arrayOf(AppModule::class, NetModule::class)) 
interface NetComponent { 
    fun inject(activity: HomeActivity) 
}

NetModule

@Module() 
class NetModule(baseUrl: String) { 

    val mBaseUrl: String = baseUrl; 

    @Provides 
    @Singleton 
    fun providedSharedPreferences(app: Application): SharedPreferences { 
     return PreferenceManager.getDefaultSharedPreferences(app); 
    } 

    @Provides 
    @Singleton 
    fun provideOkHttpCache(app: Application): Cache { 
     val cacheSize = 10 * 1024 * 1024 // 10 MiB 
     return Cache(app.cacheDir, cacheSize.toLong()) 
    } 

    @Provides 
    @Singleton 
    fun providedGson(): Gson { 
     return GsonBuilder() 
       .excludeFieldsWithoutExposeAnnotation() 
       .create(); 
    } 

    @Provides 
    @Singleton 
    fun provideOkHttpClient(cache: Cache): OkHttpClient { 
     return OkHttpClient.Builder() 
       .cache(cache) 
       .build(); 
    } 

    @Provides 
    @Singleton 
    fun provideRetrofit(gson: Gson, okHttpClient: OkHttpClient): Retrofit { 
     return Retrofit.Builder() 
       .addConverterFactory(GsonConverterFactory.create(gson)) 
       .baseUrl(mBaseUrl) 
       .client(okHttpClient) 
       .build() 
    } 

}

的AppModule

@Module() 
class AppModule(val app: App) { 

    @Provides 
    @Singleton 
    fun provideApp() = app 

}

AppComponent

@Singleton 
@Component(modules = arrayOf(AppModule::class)) 
interface AppComponent { 

    fun inject(app: App) 
}

最後，HomeActivity

class HomeActivity : AppCompatActivity() { 

    @Inject var sharedPreferences: SharedPreferences? = null; 

    override fun onCreate(savedInstanceState: Bundle?) { 
     super.onCreate(savedInstanceState) 
     setContentView(R.layout.activity_home) 
     (application as App).netComponent.inject(this) 
    } 
}

It's build failed when I start using @Inject annotation to HomeActivity Class.

發佈您的gradle日誌。 –

我在哪裏可以得到這個日誌@DmitriiNechepurenko日誌保持在哪裏 –

如果你使用android studio - 右下角的「gradle console」 –

解決了更新的AppModule

from App (which extend Application) to Application

FROM

@Module() 
class AppModule(val app: App) { 

    @Provides 
    @Singleton 
    fun provideApp() = app 

}

@Module() 
class AppModule(val app: Application) { 

    @Provides 
    @Singleton 
    fun provideApp() = app 

}

我不知道爲什麼，但也許NetModule.class，提供一些方法所需要的應用程序作爲輸入參數，所以牽引可能不知道，應用程序是由應用程序類擴展，導致無法分辨注射。

任何人都可以在此假設上確認。請確認。

您沒有包含完整的錯誤日誌。如果你已經向上捲動了一下，你會發現像這樣的東西：https://stackoverflow.com/q/44912080/1837367在你的情況下，Dagger只知道你的實現'App'，但你正在請求' Application'。你也可以通過添加'：Application'作爲kotlin返回類型，或者添加'@Binds fun bindApp（app：App）：Application'到你的模塊來解決這個問題 –

我使用Dagger2上科特林，試着這樣做：

@Inject lateinit var sharedPreferences: SharedPreferences

代替：

@Inject var sharedPreferences: SharedPreferences? = null

這樣我也解決Butterknife的問題

。

still，錯誤：執行失敗的任務'：app：kaptDebugKotlin'。 >內部編譯器錯誤。請參閱日誌以獲取更多詳細信息 –

一個問題：爲什麼在聲明依賴關係時使用實現而不是編譯？ – ste9206

@ ste0206 https://stackoverflow.com/a/44493379/2077479 –

在我面臨同樣的問題之前的某段時間，我的一天就找到了解決方案。根據我的經驗，我列出了以下幾點，開發人員在將Dagger2與android kotlin集成時必須考慮這些點。

在Component & Module類中所用的範圍必須是相同的。
apply plugin: 'kotlin-kapt必須在您的build.gradle文件中，沒有這個，您無法生成DaggerComponent類。

希望它能幫助一些開發者。
