AndroidStudio gradle配置新版阿里云maven镜像，解决​java.net.UnknownHostException: dl.google.com ​问题_failed to download any source lists! io exception

由于老项目之前也配置过阿里云镜像，最近发现依赖下得特别慢甚至下载失败报错：

Failed to download any source lists! IO exception while downloading manifest: java.net.UnknownHostException: dl.google.com

发现现在新的阿里云maven变了，更换为最新的阿里云镜像则解决, 记录一下：

//新版阿里云镜像
maven {url 'https://maven.aliyun.com/repository/public/'}
maven {url 'https://maven.aliyun.com/repository/google/'}
maven {url 'https://maven.aliyun.com/repository/central/'}
maven {url 'https://maven.aliyun.com/repository/gradle-plugin/'}
mavenLocal()
mavenCentral()
 
 
//老版的阿里云镜像
//maven {url 'https://maven.aliyun.com/nexus/content/groups/public'}
//maven {url 'https://maven.aliyun.com/nexus/content/repositories/central'}
//maven {url 'https://maven.aliyun.com/nexus/content/repositories/google'}
// maven {url 'https://maven.aliyun.com/nexus/content/repositories/google'}
