无法解析：com.google.android.gms:play-services:15.0.1

在同步 gradle 时出现以下错误，我检查了与类似问题相关的其他答案并遵循了他们的答案，但仍然出现相同的错误

无法解析：com.google.android.gms:play-services:15.0.1 安装存储库并同步项目 在文件中显示 在项目中显示 结构对话框

当我单击“安装存储库并同步项目”时，出现以下错误

找不到依赖项“com.google.android.gms:play-services:15.0.1”

以下是应用程序级别的gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "mpathak.drivetestapp"
        minSdkVersion 15
        targetSdkVersion 26

我的模块 gradle （顶级）如下

buildscript {

    repositories {
        jcenter()
        maven {url "https://maven.google.com"}
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'com.google.gms:google-services:3.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

我遵循约定，回购协议中所述

尝试没有这个implementation "com.google.android.gms:play-services:15.0.1"

但具体的图书馆喜欢

implementation "com.google.android.gms:play-services-gcm:15.0.1"
