背景：筆者所在公司經歷了三次fastjson的升級，由於集群，工程數量眾多，每次升級都很麻煩。因此開發了一個java的升級工具。
功能介紹：
功能介紹：一個jar文件，通過java -jar命令，輸入用戶名，密碼，所負責的git項目主目錄，即可對所負責的本地工作區目錄下的項目工程中的pom.xml文件進行檢測，然后對其依賴的低版本fastjson直接升級到最新版本。
pom依賴：

通過pom依賴和工具類構件maven jar
- 新建需要升級的項目工程的分支
- 構建升級jar包，放到項目空間目錄中，與其他工程項目同級
- cmd打開命令行cd到項目空間目錄中，執行命令
java -jar \pomup.jar username password http://github.com/username/xxxx
說明：pomup.jar:構建的jar包名稱
username,password :git的用戶名，密碼
http://github.com/username/xxxx：整體的git項目空間
