使用别人的android项目因为版本问题,下载失败各种包需要修改build.gradle路径

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