android - 错误 : could not find com. google.gms :google-services:4. 2.0

Question

今天我试图将 com.google.gms:google-services 从 4.1.0 更新到 4.2.0，因为它是最新版本并且 recommended通过火力基地。但是我得到这个错误:

这是我项目的构建 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 Doug Stevenson 所说，依赖项现在已启动并正在运行，因此只需在您的存储库中使用 google()。

如果您对其他 google 存储库(firebase、exoplayer)有任何问题，您可以跟踪问题进度 here .

Answer 1

因为google-services:4.2.0在Central Repository没有，所以需要从Android Tools Repository下载。要将其添加到您的项目中，请添加

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

这是构建脚本库。有关更多信息，请参阅 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'
        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:

    }

allprojects {
