准備工作：
若Jenkins是全新安裝，則要構建maven項目，還應在服務器上安裝jdk和maven並進行配置。（這里jdk的安裝不作介紹）
安裝maven

Default locale: en_US, platform encoding: UTF-8
然后在Jenkins的 系統設置-系統管理-全局工具配置 配置jdk與maven
至此，構建maven項目的准備工作已完成。
1.新建一個 maven項目 的任務（若沒有下圖中的maven項目選項，則需要從系統設置-插件管理 安裝插件Maven Integration plugin）
2.配置git
3.配置build
4.執行構建就可以啦
