AndroidStudio 加载grade失败问题解决

1:在gradle-wrapper.properties中添加国内镜像

distributionUrl=http\://mtl-gradle-mirror.oss-cn-hangzhou.aliyuncs.com/gradle-5.6.4-bin.zip

2：在build.gradle中加上阿里镜像

   repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/google/' }
        maven { url 'https://maven.aliyun.com/repository/jcenter/' }
    }
