android-lifecycle - 如何解决找不到android.arch.lifecycle :compiler?

Question

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项。

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()
}

我得到了以下错误，

Error:Could not find android.arch.lifecycle:compiler:1.0.0-beta1.
Searched in the following locations:

    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
}

你能回顾一下我做错了什么吗？

** 我的 Android Studio 版本是 2.3.3，我正在使用 Kotlin

Answer 1

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

buildscript {
    ext.kotlin_version = '1.1.50'

    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
        google()
    }

请注意，您不再需要 android.arch.lifecycle:compiler:1.0.0-beta1如果您使用的是 Java 8。 You can use android.arch.lifecycle:common-java8:1.0.0-beta1 instead .
