工具的使用与安装--JAVA 环境变量的配置

测试JAVA_HOME地址指令  echo %JAVA_HOME%

1.解压部署Maven核心程序
①检查JAVA_HOME环境变量
C:WindowsSystem32>echo %JAVA_HOME%
D:DevInstalljdk1.7.0_07
②解压Maven的核心程序
将apache-maven-3.2.2-bin.zip解压到一个非中文无空格的目录下。例如：D:DevInstallapache-maven-3.2.2
③配置环境变量
M2_HOME D:DevInstallapache-maven-3.2.2
path D:DevInstallapache-maven-3.2.2in
④查看Maven版本信息验证安装是否正确
C:WindowsSystem32>mvn -v
