kapt构建失败与匕首Android处理器
我试图用Kotlin注解处理工具 （kapt）在我的项目中包含Dagger Android处理器（ 在此记录）。
我已经在我的build.gradle文件中包含了适当的依赖关系：
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，当我建立项目，我得到以下的GradleException ：

See log for more details * Try: Run with --info or --debug option to get more log output. * Exception is: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:kaptDebugKotlin'.

根据Kotlin 1.0.4 版本更新日志 ：
只有遇到默认
kapt注释处理实现的问题时，才应该启用[generateStubs]。
我尝试过，但没有运气。
根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 }
Bah，我错过了中断之前的部分错误信息：
: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, not dagger.android.AndroidInjector.Factory. See google.github.io/dagger/android e: e: public abstract dagger.android.AndroidInjector.Factory bindMainActivityInjectorFactory(@org.jetbrains.annotations.NotNull() e: ^ w: warning: The following options were not recognized by any processor: '[kapt.kotlin.generated]' 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.
我在创建AndroidInjector.Factory时使用了方差注释而不是out注释。
@Module(subcomponents = arrayOf(MainActivitySubcomponent::class)) abstract class MainActivityModule { @Binds @IntoMap @ActivityKey(MainActivity::class) abstract fun bindMainActivityInjectorFactory( builder: MainActivitySubcomponent.Builder): AndroidInjector.Factory // Was using `in` annotation instead of `out` }
我认为这个问题与kotlin-stdlib-jre7有关 ，它不能用匕首正常工作，我建议你把kotlin-stdlib-jre7 换成kotlin-stdlib ：
compile "org.jetbrains.kotlin:kotlin-stdlib:1.1.2"
代替：
compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:1.1.2"
这个对我有用。
这个构建失败没有单一的原因。 它也不总是与kotlin有关。
在Android工作室的Gradle Console中检查您的日志以获取有关原因的明确信息。 你可以find失败的线索。
我经历了同样的问题。 我必须从我的build.gradle起飞：
-
apply plugin: 'kotlin-kapt' -
kapt 'groupId:artifactId:$kapt_version'
我加了这个（直接插上后插入：….）：
kapt { generateStubs = true }
我希望这可以帮助别人。
