android - Dagger2 不生成 Dagger 类

Question

Dagger2 不创建类 Dagger*。我创建了接口(interface) MyContainerComponent，但没有创建类 DaggerMyContainerComponent!

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        classpath "com.android.databinding:dataBinder:1.0-rc4"
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'com.frogermcs.androiddevmetrics:androiddevmetrics-plugin:0.4'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.0.6"
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

在build.gradle

apply plugin: 'com.android.application'
apply plugin: 'android-apt'
apply plugin: 'com.android.databinding'
apply plugin: 'kotlin-android'
apply plugin: 'com.frogermcs.androiddevmetrics'

    //constraint-layout
    compile 'com.android.support.constraint:constraint-layout:1.0.0-beta4'
}

kapt {
    generateStubs = true
}

MyContainerComponent.kt

package com.tegra.module.profile.ioc

@Component(modules = arrayOf(ProfileModule::class))
@Singleton
public interface MyContainerComponent {
    fun inject(profileActivity: ProfileActivity)
}

ProfileModule.kt

package com.tegra.module.profile.bl.di

@Module
class ProfileModule(val application: Application) {

    @Provides
    @Singleton
    fun provideApplication(): Application {
        return application
    }

    @Provides
    @Singleton
    fun provideContext(): Context {
        return application
    }
}

有什么解决办法吗？已经尝试过:更改 gradle 版本、清理、重建、更改依赖版本，还删除 Gradle 缓存并重新安装 Android Studio。

Answer 1

为了在 Kotlin 文件中使用 Dagger 注释，您必须为 Dagger 编译器使用 kapt:

kapt 'com.google.dagger:dagger-compiler:2.8'

此外，删除所有 apt 依赖项，因为 kapt 也处理 Java 中的注释。
