一、
Google 的Maven代码
依赖构建，需注意Gradle的版本是否低于4.1
请在Project顶级
build.gradle
文件中包含 Google 的 Maven 代码库：
allprojects {
repositories {
google()// 如果您使用的是低于 4.1 的 Gradle 版本，则必须改为使用：
// maven {
// url ‘https://maven.google.com’
// }
// An alternative URL is ‘https://dl.google.com/dl/android/maven2/’
}
}
二、配置国内镜像地址，加速依赖下载（解决依赖失败，推荐阿里云镜像）

1. 对指定的项目生效，在项目中的顶级build.gradle修改内容：
buildscript {
repositories {
maven { url ‘http://maven.aliyun.com/nexus/content/groups/public/’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/jcenter’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/google’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/gradle-plugin’ }
}
dependencies {
classpath ‘com.android.tools.build:gradle:3.4.1’
}
}allprojects {
repositories {
maven { url ‘http://maven.aliyun.com/nexus/content/groups/public/’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/jcenter’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/google’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/gradle-plugin’ }
}
}
2. 对所有项目生效，在User/.gradle/下创建init.gradle文件，内容如下:
allprojects{
repositories {
def ALIYUN_REPOSITORY_URL = ‘http://maven.aliyun.com/nexus/content/groups/public’
def ALIYUN_JCENTER_URL = ‘http://maven.aliyun.com/nexus/content/repositories/jcenter’
all { ArtifactRepository repo ->
if(repo instanceof MavenArtifactRepository){
def url = repo.url.toString()
if (url.startsWith(‘https://repo1.maven.org/maven2’)) {
project.logger.lifecycle “Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL.”
remove repo
}
if (url.startsWith(‘https://jcenter.bintray.com/’)) {
project.logger.lifecycle “Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL.”
remove repo
}
}
}
maven {
url ALIYUN_REPOSITORY_URL
url ALIYUN_JCENTER_URL
}
}
}
