匕首2在Kotlin未解决的参考

我正在尝试在我的Android项目中使用Dagger 2,并在Kotlin中进行编码。 我从Dagger 2回购Android的简单的例子。 我已经设法在Android Studio中使用来自dagger-android-gradle-sample的示例正确configuration项目,它包含正确configuration的gradle文件。

现在我开始将java类更改为kotlin。 这是自动转换的DemoApplication.java在kotlin中的样子:

 public class DemoApplication : Application() { Singleton Component(modules = array(javaClass<AndroidModule>())) trait ApplicationComponent { public fun inject(application: DemoApplication) public fun inject(homeActivity: HomeActivity) public fun inject(demoActivity: DemoActivity) } public var component: ApplicationComponent? = null override fun onCreate() { super.onCreate() component = `Dagger_DemoApplication$ApplicationComponent`.builder().androidModule(AndroidModule(this)).build() component!!.inject(this) } } 

匕首生成的类在Kotlin中可见,但它抱怨($)类名称中使用的符号。 ($)在Kotlin有特殊的目的,所以我想这就是为什么。 你可以注意到auto-convertion用(`)符号封装类名,所以编辑器不会抱怨它。 不幸的是,编译器失败:

 Error:(32, 21) Unresolved reference: `Dagger_DemoApplication$ApplicationComponent` :app:compileDebugKotlin FAILED 

如果我尝试从terminal上构build它,也有一个例外:

有谁知道如何解决这个问题? 如果不是,我将不得不在Java中使用Dagger_ *。
