前言
jenkins 是一款流行的开源持续集成（continuous integration）工具，广泛用于项目开发，具有自动化构建、测试和部署等功能。
最近参加公司的集成测试平台的开发，在开发中遇到了不少问题，两个星期的迭代也即将完成，在这也用这篇博客记录下开发中的问题，供读者参考
公司的应用较多，所以需要了解这几种应用在jenkins中如何做构建，我自己参与的有两种commander的应用，一种是大数据类的，一个是我们服务端架构组的scala应用
1、大数据应用bigdata
配置如下：
配置文件对应的xml文件：通过crul获取xml配置文件：http://host/job/tar_py_dwx_dev/config.xml
我要评论

从xml中获取的信息有点和图中的配置文件有点对应不上
对于promotion的脚本在xml配置文件中是无法获取的，这时候就有一个问题，这种api是无法获取到promotion的的脚本，同时这也给我们的工作带来了极大的挑战，那也意味着单纯的通过这种方法是无法实现commander应用的部署，和通过平台的方式去直接操作jenkins的配置
但经过查询相关的api并不能找到相关的内容，经过不懈的努力，终于找到了和promote build 插件相关的api
查询：http://host/job/jobname/promotion/process/promotionname/config.xml
这个接口能获取到它的xml文件，但是并不能对该配置文件进行增加和修改
对此我自己封装了一些方法：
