錯誤：找不到com.google.gms：google-services：4.2.0

Question

今天，我正嘗試將com.google.gms：google-services從4.1.0更新到4.2.0，因為它是最新版本，並由firebase 推薦 。 但是我得到這個錯誤：

Could not find com.google.gms:google-services:4.2.0.

這是我的項目的構建gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
        google()
        maven {
            url 'https://maven.fabric.io/public'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.2.0'

        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.8.4'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
        // These docs use an open ended version so that our plugin
        // can be updated quickly in response to Android tooling updates

        // We recommend changing it to the latest version from our changelog:
        // https://docs.fabric.io/android/changelog.html#fabric-gradle-plugin
        classpath 'io.fabric.tools:gradle:1.27.0'
    }
}

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

更新：

正如道格·史蒂文森（Doug Stevenson）所說，該依賴關系現已啟動並正在運行，因此只需在您的存儲庫中使用google（）。

如果您對其他Google存儲庫（firebase，exoplayer）有任何疑問，可以在此處跟蹤問題的進展。

發現jCenter上缺少Google Play服務插件，Firebase Performance監視插件，exoplayer和其他可能的依賴項。 目前尚不清楚原因，但已知有些團隊將其構建工件移至Google Maven存儲庫。

截至目前，Google Play服務插件已遷移，現在應該可以通過buildscript中的google（）使用。

Answer 2

由於google-services：4.2.0在中央存儲庫中不可用，因此需要從Android工具存儲庫下載。 要將其添加到您的項目中，請添加

maven { url 'https://dl.bintray.com/android/android-tools' }

這可以建立腳本存儲庫。 有關更多信息，請參閱https://mvnrepository.com/artifact/com.google.gms/google-services/4.2.0

buildscript {
    repositories {
        jcenter()
        google()
        maven {
            url 'https://maven.fabric.io/public'
        }
        //  Add this to your project 
        maven { url 'https://dl.bintray.com/android/android-tools' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.2.0'

        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.8.4'

試試這個，為我工作：

buildscript {
    repositories {
        google()
        //jcenter()
        jcenter {url 'https://dl.bintray.com/android/android-tools'}
        jcenter {url 'https://firebase.bintray.com/gradle'}
        mavenCentral ()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.2.0'
        classpath 'com.google.firebase:firebase-plugins:1.1.5'
    }
}

allprojects {
    repositories {
        google()
        //jcenter()
        jcenter {url 'https://dl.bintray.com/android/android-tools'}
        jcenter {url 'https://firebase.bintray.com/gradle'}
        mavenCentral ()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Answer 4

google-services：4.2.0現在又回到了Google Maven存儲庫，只需使用默認配置同步gradle：

allprojects {
    repositories {
        google()
        jcenter()
    }
}
