Android Studio Gradle构建很慢，下载依赖缓慢问题_androidstudio无法下载gradle依耐文件

在项目的 build.gradle或setting.gradle（Android Studio新老版本配置不同）中配置镜像源

阿里云：

maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
maven { url 'https://maven.aliyun.com/repository/spring-plugin' }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/central' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'https://maven.aliyun.com/repository/public' }
maven { url 'https://jitpack.io' }

或

maven { url=uri("https://maven.aliyun.com/repository/gradle-plugin") }
maven { url=uri("https://maven.aliyun.com/repository/spring-plugin") }
maven { url=uri("https://maven.aliyun.com/repository/google") }
maven { url=uri("https://maven.aliyun.com/repository/central") }
maven { url=uri("https://maven.aliyun.com/repository/jcenter") }
maven { url=uri("https://maven.aliyun.com/repository/public") }
maven { url=uri("https://jitpack.io")}
