背景：笔者所在公司经历了三次fastjson的升级，由于集群，工程数量众多，每次升级都很麻烦。因此开发了一个java的升级工具。
功能介绍：
功能介绍：一个jar文件，通过java -jar命令，输入用户名，密码，所负责的git项目主目录，即可对所负责的本地工作区目录下的项目工程中的pom.xml文件进行检测，然后对其依赖的低版本fastjson直接升级到最新版本。

通过pom依赖和工具类构件maven jar
- 新建需要升级的项目工程的分支
- 构建升级jar包，放到项目空间目录中，与其他工程项目同级
- cmd打开命令行cd到项目空间目录中，执行命令
java -jar pomup.jar username password http://github.com/username/xxxx
说明：pomup.jar:构建的jar包名称
username,password :git的用户名，密码
http://github.com/username/xxxx：整体的git项目空间
