Gradle使用阿里云国内镜像

老是查，记录下。。。

在项目build.gradle中添加：

buildscript {
    repositories {
        maven {
            url 'http://maven.aliyun.com/nexus/content/groups/public/'
        }
        maven {
            url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'
        }
    }
}

allprojects {
    repositories {
        maven {
            url 'http://maven.aliyun.com/nexus/content/groups/public/'
        }
        maven {
            url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'
        }
    }
}
