Dagger2 不创建类 Dagger*。我创建了接口 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'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.tegra.module.profile"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:25.1.1'
    testCompile 'junit:junit:4.12'
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

    kapt 'com.android.databinding:compiler:1.0-rc4'

    //dagger
    compile 'com.google.dagger:dagger:2.8'
    apt 'com.google.dagger:dagger-compiler:2.8'

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

kapt {
    generateStubs = true
}

我的容器组件.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，同时删除 Gradle 缓存并重新安装 Android Studio。

为了在Kotlin文件中使用 Dagger 注释，您必须使用kaptDagger 编译器：

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

此外，删除所有apt依赖项，因为kapt在 Java 中也处理注释。
