kapt构建失败，伴随着Dagger Android处理器

androidkotlindagger-2kapt
21

我正在尝试在我的项目中使用Kotlin Annotation Processing Tool (kapt)来包含Dagger Android Processor（文档在这里）。

我已经在我的build.gradle文件中包含了正确的依赖项：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.example.app"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

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'
        exclude group: 'com.google.code.findbugs', module: 'jsr305'
    })

    // Support libraries
    compile "com.android.support:appcompat-v7:25.3.1"
    compile "com.android.support:design:25.3.1"
    compile "com.android.support.constraint:constraint-layout:1.0.2"

    // Google libraries
    compile "com.google.dagger:dagger-android:2.10"
    compile "com.google.dagger:dagger-android-support:2.10"
    kapt "com.google.dagger:dagger-android-processor:2.10"

    // ReactiveX libraries
    compile "io.reactivex.rxjava2:rxandroid:2.0.1"
    compile "io.reactivex.rxjava2:rxjava:2.0.9"

    // Kotlin libraries
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:1.1.2"

    // Test instrumentation
    testCompile "junit:junit:4.12"
}

但是当我构建项目时，出现了以下的 GradleException 异常：

根据Kotlin 1.0.4 发布日志：

仅在使用默认的kapt注解处理实现遇到问题时，才应启用[generateStubs]。

我尝试了这个方法，但没有成功。

根目录 build.gradle：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2"
        classpath "com.android.tools.build:gradle:2.3.1"
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
你能展示一下你的根目录下的 build.gradle 文件吗？ - Christian Brüggemann
@ChristianBrüggemann 当然可以。 - Bryan

啊，我错过了断点之前的一部分错误信息：

:app:kaptDebugKotlin
e: /Users/me/Downloads/App/app/build/tmp/kapt3/stubs/debug/com/example/app/ui/module/main/MainActivityModule.java:10: error: @dagger.android.ActivityKey methods should bind dagger.android.AndroidInjector.Factory<? extends android.app.Activity>, not dagger.android.AndroidInjector.Factory<? super android.app.Activity>. See google.github.io/dagger/android

w: 


e: /Users/me/Downloads/App/app/src/main/kotlin/com/example/app/ApplicationComponent.kt: (1, 1): Some error(s) occurred while processing annotations. Please see the error messages above.

在创建 AndroidInjector.Factory 时，我使用了 in 变量注释而不是 out 注释。

@Module(subcomponents = arrayOf(MainActivitySubcomponent::class))
abstract class MainActivityModule {

    @Binds @IntoMap @ActivityKey(MainActivity::class)
    abstract fun bindMainActivityInjectorFactory(
            builder: MainActivitySubcomponent.Builder): AndroidInjector.Factory<out Activity> // Was using `in` annotation instead of `out`
}

你能否详细说明一下解决方案？我不太明白。 - Semanticer

在Java中，通配符可以是无限制的，上限或下限，分别使用没有关键字、extends关键字或super关键字。这些关键字对应于Kotlin中的in和out变异注释。错误说明我在使用extends时应该使用super；或者在转换为Kotlin时，应该使用out而不是in。 - Bryan
@JohnErnestGuadalupe 你想要生成相同的错误日志吗？你应该只需要复制上面的 MainActivityModule，但使用 in 变异 (AndroidInjector.Factory<in Activity>)，并将其添加到你的 AppComponent（或任何你的 Dagger 对象图的部分）中。 - Bryan

你希望 kapt 的错误能够显示在标准的 Studio 错误日志窗口中吗？我非常希望。 - G. Blake Meike

我认为这个问题与kotlin-stdlib-jre7有关，它与dagger的兼容性存在问题。我建议你将kotlin-stdlib-jre7更换为kotlin-stdlib：

compile "org.jetbrains.kotlin:kotlin-stdlib:1.1.2"

替代：

compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:1.1.2"

对我有效。

这个解决方案对我起到了作用。 - DimitrisCBR

我曾经遇到过同样的问题。

  1. apply plugin: 'kotlin-kapt'
  2. kapt 'groupId:artifactId:$kapt_version'

我必须从我的 build.gradle 文件中删除这些内容，并添加以下内容（直接在 apply plug:... 之后）：

kapt {
    generateStubs = true
}

我希望这能帮助到其他人。

如果你已经使用了kotlin-kapt插件，就不需要使用generateStubs = true，因为这是用于旧版kapt的。Gradle会显示出对此的警告。 - yanex

此构建失败原因不是单一的，也不总是与 kotlin 有关。

请在Android Studio的Gradle控制台中检查日志，以获取有关原因的清晰信息。 您可以从日志中找到故障线索。

我尝试了许多方法，但在第二天添加了 MoviesViewModel @Inject constructor(private val movieService: MovieService): ViewModel() 后，错误信息并不有意义。 :)

我曾遇到与kapt有关的类似问题，我解决了它，方法是添加以下内容：
apply plugin: 'kotlin-kapt'

并且

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

去Android Studio的SDK管理器中安装NDK，这对我有效。
