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

Question

Maybe the question was asked before but I found a very strange kind of error. When I run mvn --version command from bin it gives the version and the other information. However when I run outside the bin it gives an exception. Both the result mention below

C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5\bin>mvn --version 
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 19:21: 
28+0530) 

Maven home: C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5 
Java version: 1.7.0_25, vendor: Oracle Corporation 
Java home: C:\Program Files\Java\jdk1.7.0_25\jre 
Default locale: en_US, platform encoding: Cp1252 
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows" 

C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5>mvn --version 
'mvn' is not recognized as an internal or external command, 
operable program or batch file.

Also I set JAVA_HOME in the user variable and M2_HOME, M2 in the system environment variable. The output for these variables and %path% is:

C:\Users\SAHILBHALLA>echo %JAVA_HOME% 
C:\Program Files\Java\jdk1.7.0_25 

C:\Users\SAHILBHALLA>echo %M2% 
C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5\bin 

C:\Users\SAHILBHALLA>echo %M2_HOME% 
C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5 

C:\Users\SAHILBHALLA>echo %path% 
C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPow erShell\v1.0\;C:\Program Files\Java\jdk1.7.0_25\bin;.;

Tell me where I am wrong. What should I do to recover from it?

While I was solving this problem, the path didn't resolve %M2%. When i added the location of maven-bin in the path instead of %M2% after that commands worked.
