本文主要根据Jenkins上的日志来继续说明构建项目的过程，上文我们已经讲到构建一个测试环境或单独终端的过程，详情可以了解上篇文章
一、背景介绍
首先看下SVN代码的仓库的结构：
代码仓库里有一个文件夹，可以随便取名，文件夹中可以放置很多单独的项目，每个项目下有branch，trunk，demand三个文件。在branch下面可以有pc端，微信端，
APP端，后台等终端，从下面的结构中，可以看出每个终端的代码中有资源文件夹src（类的定义，配置文件，说明文档，jar包等）和pom文件。
二、构建trunk项目
当发布正式环境时需先先构建trunk，然后发布正式项目，因此此时需要注意，如果有项目功能没有写完，不能直接构建trunk，此时构建trunk会将仓库下所有项目修改或更新的部分全部更新到Jenkins工作目录中。
1、Jenkins中的SVN地址：
构建正式环境：需要构建trunk，将代码仓库中所有变动的代码和Jenkins工作目录中的代码对比，然后更新Jenkins工作目录的代码
3.4版本trunk地址
https://101.21.101.111:443/svn/代码仓库/branches/qianrongyiV3.4（项目下有web，APP，WeChat等终端）
.4版本正式项目地址：
https://101.21.101.111:443/svn/代码仓库/branches/qianrongyiV3.4/qian-web（pom文件）（单独web终端） 构建预发布环境：不需要构建trunk，只需要单独构建项目即可，将单独项目变动部分更新。
.4版本预发布环境：
https://101.21.101.111:443/svn/代码仓库/branches/qianrongyiV3.4/qian-app
2、构建3.4版本trunk的过程：

3、Jenkins上trunk配置：
部分1、Maven project name 栏设置
主要填写Maven project name(工程名)、Descript(工程描述信息)
部分2、Source Code Management 栏设置
输入源码的获取地址，由于我的插件中演示的是svn,那么如下输入：
Repository depth: Jenkins在执行checkout、update代码时，所取出的代码的范围。默认我们选择infinity就可以。
Check-out Strategy：svn第一次更新代码和以后同步代码的步骤，和策略。默认选项一般就可以。
部分3、Build Triggers 栏设置
默认选项为：
Build whenever a SNAPSHOT dependency is buil 意思就是svn更新触发构建
这里建议选择：
Poll SCM 相当于新建一个计划任务，定时检查版本库，发现有新的提交就触发构建。其配置的意思和linux的crontab差不多,如10分钟构建一次
部分4、Build 栏设置
如果对mvn构建参数有需求，或者需要设置pom.xml的文件位置，可以在这里设置。
默认： pom.xml的文件就在工程目录下。
部分5、完成
点 save 完成对一个一个工程的设置
4、构建trunk的结果：
