由于是第一个项目，之前一直都是手动打包，所以最近要看看ci打包的事情！
知识前提
以上这三个是必然会使用到的！如果还没有接触的可以自行去看看官方的连接！
文档上的知识在这里就不照搬了！进入主题吧！
基本的结构
All.xml是所有任务的汇总Properties.xml是整个自动化用到的属性（变量）Reset.xml是用来按需配置打包的，不用平台可能有不同的需求PakResource.xml是pak资源的BuildScript.xml是编译和打包的
过程及问题
ci 环境的搭建
具体的xml以及注意
All.xml
All.xml是一个汇总，文件划分已经做好的
All.xml
<?xml version='1.0' ?>
<BuildGraph xmlns="http://www.epicgames.com/BuildGraph" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.epicgames.com/BuildGraph ../Schema.xsd" >
<Include Script="Properties.xml"/>
<Include Script="Reset.xml"/>
<Include Script="BuildScript.xml"/>
<Include Script="PakResource.xml"/>
<Aggregate Name="All" Requires="Properties Module;Reset Module;Pak Resource Module;Build Script Module"/>
<Aggregate Name="Reset" Requires="Properties Module;Reset Module"/>
<Aggregate Name="Pak" Requires="Properties Module;Build Project;Pak Resource Module"/>
<Aggregate Name="Build" Requires="Properties Module;Build Script Module"/>
</BuildGraph>
这里有个问题，如果是
Aggregate所依赖的Modeule有交叉的话，最好是把所有的Aggregate都写到一个大的xml中！
Properties.xml
Properties.xml基本是属性的声明
目前项目使用到了lua，需要对Lua进行单独的pak打包
Properties.xml
<?xml version='1.0' ?>

因为是
Properties， 所以字符串是少不了的，但是需要注意xml的一些转码！ 这里提供目前我使用的，如果是其他的，可以自行google哈": “
: 换行

这个目前只是用来打包lua的，至于以后会不会将资源cook和独立打包资源也加进去就待定了！
