I've also appended next in the path:
我还在路径中添加了 next：
%M2% But it still not working.
%M2% 但还是不行。
I can execute 'mvn -version' from the D:\Maven\bin but can't do this from another directory.
我可以从 D:\Maven\bin 执行 'mvn -version' 但不能从另一个目录执行此操作。
Thanks in advance!

Don't put extra space in your path after D:\Maven\bin; in D:\Maven\bin; D:\Program Files\NodeJS; Please don't make any space in path variable.
不要在 D:\Maven\bin 之后的路径中放置额外的空间；在 D:\Maven\bin 中；D:\Program Files\NodeJS; 请不要在路径变量中留出任何空间。

通常，要在 windows 的命令行中设置 mvn ：
- Set JAVA_HOME property in system environment
eg.JAVA_HOME=C:\Program Files\Java\jdk1.8.0_65 - Set M2_HOME property in system environment
eg.M2_HOME=D:\apache-maven-3.3.3 Finally add maven to PATH

- 在系统环境中设置 JAVA_HOME 属性，
例如。JAVA_HOME=C:\Program Files\Java\jdk1.8.0_65 - 在系统环境中设置 M2_HOME 属性，
例如。M2_HOME=D:\apache-maven-3.3.3 最后将 maven 添加到 PATH
;%M2_HOME%\bin;将此添加到系统环境的 PATH 属性的末尾
Now Try mvn -version

Try to put full maven path upto bin like "C:\Users\ABC\Downloads\maven-2.0.5-bin\maven-2.0.5\bin" directly into path variable of os, then you will be able to understand where problem exists.
尝试将完整的maven路径upto bin像“ C:\Users\ABC\Downloads\maven-2.0.5-bin\maven-2.0.5\bin”直接放入os的路径变量中，然后你就可以理解在哪里问题存在。
