Android 未能解决：播放服务任务许可证（将google（）放在jcenter（）之前不起作用）

每当我尝试运行我的应用程序时，我都会出现以下gradle错误：

未能解析：播放服务任务许可证

根据问题，我已经尝试了所有可能的解决方案，但没有一个奏效

如果我将google（）放在依赖项的第一行，错误仍然会出现。

如果可以的话，请帮忙

我认为您需要更改项目级别

build.gradle

文件，如下所示：

buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'

        classpath 'io.fabric.tools:gradle:1.+'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

把这个拿走

repositories {
    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
    maven { url "https://jitpack.io" }
    maven { url 'https://maven.fabric.io/public' }
}

还有这个

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

从应用程序

PS：您也可以删除

实现文件（'libs/youtube.jar'）

，因为您已经在导入带有以下行的库：
