I get the following error when I type the command mvn --version:

'mvn' is not recognized as an internal or external command, operable program or batch file.

I have also followed this but still I am unable to get the work done.

when I type this command echo %M2_HOME% I get path printed as D:\Program Files\apache-maven-3.0.4 when I type 'echo %M2%' I get the path printed as D:\Program Files\apache-maven-3.0.4\bin

Environment : Windows XP

Thanks for the guy who downvoted and suggested for close, instead should have given reason for doing so when you are not able to answer. – Java Questions
The bin folder needs to be set on your %PATH% environment variable. The other variables are irrelevant in order to execute the batch from the shell. Have a look at %PATH% – Andreas Dolk
@Andreas_D than please suggest me the CORRECT SITE – Java Questions
make sure to relanuch your cmd window after changing path – Denis Tulskiy
There are a lot of sites, there is no "correct site". It's just that this SO site should only be used for programming related question (like: when you have maven up and running but trouble with build definition files). Your problem is "out of scope" according to the rules. Was my comment above helpful? – Andreas Dolk

Make sure you have your maven bin directory in the path and the JAVA_HOME property set

On my Windows 7 machine I have the following environment variables:

  • JAVA_HOME=C:\Program Files\Java\jdk1.7.0_07

  • M2_HOME=C:\apache-maven-3.0.3

On my PATH variable, I have (among others) the following:

  • %JAVA_HOME%\bin;%M2_HOME%\bin

I tried doing what you've done with %M2% having the nested %M2_HOME% and it also works.

Add maven directory /bin to System variables under the name Path.

To check this, you can echo %PATH%
