【问题记录】Cordova打包出现dl.google.com或Gradle相关错误

问题描述

最近打了几次包，通过修改hosts文件的方式连接上了国内的dl.google.com的镜像站点，但是这个方法太low了，每次打包都可能面对失败的问题。之后发现其实国内有提供Gradle的镜像服务，例如源码中国和阿里云。

解决办法

1. 修改 platform > android 目录下的 build.gradle 文件。
2. 在 buildscript > repositories 节点 新增

maven{
    name "aliyunmaven"
    url "http://maven.aliyun.com/nexus/content/groups/public/"
}

在 allprojects>repositories 节点新增

maven{
    name "aliyunmaven"
    url "http://maven.aliyun.com/nexus/content/groups/public/"
}

完整build.gradle
