經(jīng)常部署maven項目會遇到很尷尬的事情，所以還是要熟練掌握一些 maven奇淫技巧和命令是很有必要的。
命令格式：

mvn [options] [<goal(s)>] [<phase(s)>]

可以通過mvn -h查看命令幫助旧巾。

一、多module項目中的一些命令

假設(shè)項目module分塊如圖1.1 所示,module C 依賴module A,B忍些，且module A,B,C的parent都是用module yp鲁猩。

圖1.1 項目結(jié)構(gòu)圖

1. mvn clean install -pl A,B

-pl用來指定需要bulid的工程 A,B,多個工程用逗號隔開。

2. mvn clean install -pl A,B -am

-am bulid工程list并且也build A,B require的工程D罢坝。這里require是指parent工程D廓握。

3. mvn clean install -pl A,B -amd

-amd build 項目list，且build 依賴A,B的項目如C嘁酿。
