Maven: mvn command not found
提问by Roaz
I set the following system veriables (OS = Vista):

If i run mvn -- version I get:

If you are on windows, what i suppose you need to do set the PATH like this:
如果您在 Windows 上，我想您需要像这样设置 PATH：
SET PATH=%M2%
furthermore i assume you need to set your path to something like C:...\apache-maven-3.0.3\ cause this is the default folder for the windows archive. On the other i assume you need to add the path of maven to your and not set it to only maven so you setting should look like this:
此外，我假设您需要将路径设置为 C:...\apache-maven-3.0.3\ 之类的内容，因为这是 Windows 存档的默认文件夹。另一方面，我假设您需要将 maven 的路径添加到您的而不是将其设置为仅 maven，因此您的设置应如下所示：
SET PATH=%PATH%;%M2%

I tried solutions from other threads. Adding M2 and M2_HOME at System variables, and even at User variables. Running cmd as admin. None of the methods worked.
我尝试了其他线程的解决方案。在系统变量甚至用户变量中添加 M2 和 M2_HOME。以管理员身份运行 cmd。没有一种方法奏效。
But today I added entire path to maven bin to my System variables "PATH" (C:\Program Files (x86)\Apache Software Foundation\apache-maven-3.1.0\bin) besides other paths, and so far it's working good. Hopefully it'll stay that way.
但是今天我将 maven bin 的整个路径添加到我的系统变量“PATH”（C:\Program Files (x86)\Apache Software Foundation\apache-maven-3.1.0\bin）除了其他路径之外，到目前为止它运行良好. 希望它会一直这样。

I think the problem is with the spaces. I had my variable at the System variables but it didn't work. When I changed variable Progra~1 = 'Program Files'everything works fine.
我认为问题出在空格上。我在系统变量中有我的变量，但它不起作用。当我更改变量时，Progra~1 = 'Program Files'一切正常。
M2_HOME C:\Progra~1\Maven\apache-maven-3.1.1
I also moved my M2_HOMEat the end of the PATH(%M2_HOME%\bin)I'm not sure if this has any difference.
我也在最后移动M2_HOME了PATH(%M2_HOME%\bin)我的我不确定这是否有任何区别。

- Run 'path' in command prompt and ensure that the maven installation directory is listed.
- Ensure the maven is installed in 'C:\Program Files\Maven'.
- 在命令提示符下运行“ path”并确保列出了 maven 安装目录。
- 确保 maven 安装在“C:\Program Files\Maven”中。
