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

Question

May be question is asked before but i found very strange kind of error. When I run mvn --version command from bin its gives the version and the other information. However when I run outside bin it gives 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:

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 user variable and M2_HOME, M2 in 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 recover from it?

Answer 1

My problem solved, path didn't resolve %M2%. When i added location of maven-bin in the path instead of %M2% after that commands works.

I would like to thanks to all those who try to solve the problem

Answer 2

This problem arise because there is no any environmental variable corresponding to installed maven in your OS. For fixing this problem, I always use Intellij's bundled Maven and do not install separate version of Maven again, for finding bundled Maven's path go to intellij and hit Ctrl+Alt+S -> Build, Execution, Deployment -> Build tool -> Maven -> Maven home directory you can find the intellij's bundled maven path there as below image demonstrates.

Then go to System environment variables and set these variables:

Variable name: MAVEN_HOME

Variable value: C:/Program Files/JetBrains/IntelliJ IDEA 2019.3.1/plugins/maven/lib/maven3

After defining system variable MAVEN_HOME find variable path and add this line to the list

%MAVEN_HOME%\bin

Work is done, open command prompt and test it by writing mvn -v. 99 percent of the time it work, if you're among 1 percent, you have to restart your computer.

If you want to use mvn command from intellij's internal terminal you have to restart intellij after setting environment variables, then you shouldn't have any problem running maven command from terminal.
