Apache Maven 安装“'mvn' 未被识别为内部或外部命令"设置操作系统环境变量后? [英] Apache Maven install "'mvn' not recognized as an internal or external command" after setting OS environmental variables?

问题描述

我已按照官方安装说明此处针对 Windows XP.但有时当我执行 mvn --version 时，我收到错误信息，

I've followed the official installation instructions here for Windows XP. But sometimes when I execute mvn --version, I receive the error message,

'mvn' 未被识别为内部或外部命令

'mvn' not recognized as an internal or external command

我什至重新启动了我的机器几次，但操作系统并不总是识别 maven 命令.但是当我执行 cd %M2_HOME% 或 cd %M2% 时，它会将我带到安装目录.我还确保将用户变量 M2 添加到 Path 系统变量.

I've even rebooted my machine a couple times, but the OS does not always recognize the maven command. But when I execute either, cd %M2_HOME%, or cd %M2% it brings me to the installation directory. I've also made sure to add the user variable M2 to the Path system variable.

那么，是什么?

推荐答案

解决方案是将 M2 从 user 变量移动到 system 变量

Way around would be moving M2 from user variables to system variables
