maven2安装步骤：
(1)maven官方下载地址：http://maven.apache.org/download.html，下载最新版本的maven软件，当前最新版本为apache-maven-2.2.1，解压到指定目录instealPath；
(2)设置系统环境变量:
       M2_HOME=%instealPath%
       PATH=%M2_HOME%\bin
(3)在console里输入mvn -version验证安装成功；
(4)配置repository的路径(本地数据仓库目录，即存放从远程下载的JAR包，默认路径是C:\Documents and Settings\Administrator\.m2\repository)，在%instealPath%\conf目录下找到settings.xml，打开修改
