安装给定的插件就行，如果插件没有，后面可以自己安装缺少的插件
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814150618553-1538402837.png
安装插件后，出现如下图：

然后点击下一步：

到这里jenkins的简单安装已经完成了，现在开始进行设置jenkins吧：
由于新版的jenkins没有deploy和maven插件，所以先给这两个插件装上：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814151334818-633429943.png

https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814151440615-1759290480.png
勾选上需要安装的插件：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814151518990-696647231.png
直接在线安装：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814151613146-1916284913.png
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814151634037-725453761.png
然后再安装maven插件：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814151732631-828398729.png
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814151756068-1902853562.png
然后回到管理设置页面，设置全局环境：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814151927225-970317759.png
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814152039271-878372421.png
去掉自动安装这个钩钩
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814152138943-1175362887.png
设置好java和maven环境变量就行，然后apply并save保存：
接下来为svn创建账号，因为连接svn需要账号：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814152545053-1504000639.png
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814152605928-1005165093.png
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814152627303-1378182627.png
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814152733975-2094538453.png
这里创建的账号就是能够连接svn的账号一致：
创建完svn账号后，基本设置已经完成，现在开始创建一个任务：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814152844068-375666450.png
箭头所指的都可以
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814152916412-1719363746.png
在没有安装maven插件的时候，高版本的jenkins这里是没有maven project模板的，所以之前快速的安装了maven插件：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814153025006-52142519.png
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814153100506-966083172.png
然后接下来都默认就可以，因为这里只是演示最简单的自动构建war包：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814153349506-1130406647.png
svn只需要源码加上pom.xml文件就行：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814153610709-379807645.png
然后点击build now快速构建：
查看控制台输出：
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814153704584-1542080427.png
https://images2017.cnblogs.com/blog/1168897/201708/1168897-20170814153914631-261647321.png
当控制台输出上面信息表示自动构建完成，生成的war包就在上面信息中
# ll /root/.jenkins/workspace/maven_test/target/testMaven-0.0.1-SNAPSHOT.war
-rw-r----- 1 root root 2229933 Aug 14 15:38 /root/.jenkins/workspace/maven_test/target/testMaven-0.0.1-SNAPSHOT.war
然后就可以拿着这个war包进行部署了，后期可以使用脚本将生成的war替换tomcat下webapps中的war，实现自动部署
