如何解决找不到android.arch.lifecycle：编译器？

我正在尝试使用Android生命周期，但我正在添加生命周期编译器依赖。

这是模块build.gradle，

apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-kapt' android { compileSdkVersion 25 buildToolsVersion "26.0.0" dataBinding { enabled = true } defaultConfig { applicationId "com.example.jj.mvvm" minSdkVersion 19 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' } } } 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' }) compile 'com.android.support:appcompat-v7:25.3.1' compile 'com.android.support.constraint:constraint-layout:1.0.2' testCompile 'junit:junit:4.12' compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" kapt 'com.android.databinding:compiler:2.3.3' implementation "android.arch.lifecycle:runtime:1.0.0" implementation "android.arch.lifecycle:extensions:1.0.0-beta1" kapt "android.arch.lifecycle:compiler:1.0.0-beta1" } repositories { mavenCentral() } 

我得到了下面的错误，

 Error:Could not find android.arch.lifecycle:compiler:1.0.0-beta1. Searched in the following locations: file:/C:/Users/jj/AppData/Local/Android/android-sdk/extras/m2repository/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.pom file:/C:/Users/jj/AppData/Local/Android/android-sdk/extras/m2repository/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.jar file:/C:/Users/jj/AppData/Local/Android/android-sdk/extras/google/m2repository/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.pom file:/C:/Users/jj/AppData/Local/Android/android-sdk/extras/google/m2repository/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.jar file:/C:/Users/jj/AppData/Local/Android/android-sdk/extras/android/m2repository/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.pom file:/C:/Users/jj/AppData/Local/Android/android-sdk/extras/android/m2repository/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.jar file:/C:/Program Files/Android/Android Studio/gradle/m2repository/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.pom file:/C:/Program Files/Android/Android Studio/gradle/m2repository/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.jar https://jcenter.bintray.com/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.pom https://jcenter.bintray.com/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.jar https://repo1.maven.org/maven2/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.pom https://repo1.maven.org/maven2/android/arch/lifecycle/compiler/1.0.0-beta1/compiler-1.0.0-beta1.jar Required by: project :app 

这是项目build.gradle文件，

 // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { ext.kotlin_version = '1.1.50' repositories { jcenter() google() } dependencies { // classpath 'com.android.tools.build:gradle:2.3.3' classpath 'com.android.tools.build:gradle:3.0.0-beta4' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } } allprojects { repositories { jcenter() } } task clean(type: Delete) { delete rootProject.buildDir } 

你能检查我在做什么错吗？

**我的Android工作室版本是2.3.3，我正在使用Kotlin

Answer 1

尝试将maven { url 'https://maven.google.com' }到您的构建脚本存储库中：

 buildscript { ext.kotlin_version = '1.1.50' repositories { jcenter() maven { url 'https://maven.google.com' } google() } 

请注意，如果您使用的是Java 8，则不再需要android.arch.lifecycle:compiler:1.0.0-beta1 。 您可以android.arch.lifecycle:common-java8:1.0.0-beta1使用android.arch.lifecycle:common-java8:1.0.0-beta1 。
