# -----------------
# M2_HOME - location of maven2's installed home dir
# MAVEN_OPTS - parameters passed to the Java VM when running Maven
# e.g. to debug Maven itself, use
# set MAVEN_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000

由上可知：

必须的环境变量为 ：JAVA_HOME 

可选的环境变量为：M2_HOME 等

还需将 %M2_HOME%/bin 设置到path

 

安装步骤：获取版本，解压，设置环境变量，设置path

验证安装成功：

mvn --version
