maven周期及项目中的应用：
周期如下：
1、default生命周期，部署项目（jar包的依赖管理）
2、clear生命周期，项目清理工作
3、site生命周期，处理项目中产生的文档信息
应用：
1、管理项目，添加jar包的依赖
2、可以把项目上传到git远程仓库，具体步骤如下
（1）：ideal 配置好git
（2）：在pom.xml中加入如下配置(注意放的位置)
(a):<scm>
(b):
现在基本配置好了。接下来是命令的执行：
mvn scm:checkin -Demessage="代码提交的说明" #这句命令是执行把代码提交到远程git仓库
mvn scm:update #代码更新，即把代码从远程仓库里面下载下来
下面是发布项目的配置
1：引入release 插件
2：引入tomcat7-maven-plugin插件
3：命令执行
mvn release:clean #发布前的清理
mvn release:prepare #发布版本
mvn release:rollback #回滚版本
下面是pom.xml的全部配置（依赖看个人需要，我这里是添加了这些依赖，项目需要的）
