android - Kapt，Kotlin，Dagger2 注释处理时出错

Question

在使用 kotlin 的项目中添加 com.google.dagger:dagger-android-support 依赖项后，我遇到了这个 gradle 错误。

这是我构建 gradle 的一部分 build.gradle

    apply plugin: 'com.android.application'
    apply plugin: 'kotlin-android'
    apply plugin: 'realm-android'
    apply plugin: 'me.tatarka.retrolambda'
    apply plugin: 'kotlin-kapt'

    android {
      ...
       kapt {
         generateStubs = true
       }
    }
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    ...
       kapt "com.google.dagger:dagger-compiler:${daggerVersion}"
       kapt "com.google.dagger:dagger-android-processor:${daggerVersion}"
       compile "com.google.dagger:dagger:${daggerVersion}"
       compile "com.google.dagger:dagger-android-support:${daggerVersion}"

       ...
    }

这里是 gradle 错误 我得到了

ApplicationComponent.java:21: error: [dagger.android.AndroidInjector.inject(T)] java.util.Map<java.lang.Class<? extends android.support.v4.app.Fragment>,javax.inject.Provider<dagger.android.AndroidInjector.Factory<? extends android.support.v4.app.Fragment>>> cannot be provided without an @Provides-annotated method.

应用组件

@Singleton
@Component(modules = {AndroidInjectionModule.class, ApplicationModule.class, RetrofitModule.class, ActivityBuilderModule.class})
public interface ApplicationComponent {

    @Component.Builder
    interface Builder {

        @BindsInstance
        Builder application(Application application);

        ApplicationComponent build();
    }

    void inject(TaskApplication application);
}

有人遇到过同样的问题吗？

在我使用 android.support.v4.app.Fragment 后使用 AndroidSupportInjectionModule 解决。

@Singleton
@Component(modules = {AndroidSupportInjectionModule.class, ApplicationModule.class, RetrofitModule.class, ActivityBuilderModule.class})
public interface ApplicationComponent {

    @Component.Builder
    interface Builder {

        @BindsInstance
        Builder application(Application application);

        ApplicationComponent build();
    }

    void inject(TaskApplication application);
}
