mvn' is not recognized as an internal or external command - windows

Question

I have created these variables with their respective values, but even after doing this, command prompt is not recognizing mvn command
System Variables:
name: M2_HOME
value: C:\Program Files\apache-maven-3.2.1
name: M2
value: %M2_HOME%/bin;
name: path
value: %JAVA_HOME%\bin; %M2_HOME%\bin;

Answer 1

From Maven documentation page:
Maven, like many cross-platform tools, can encounter problems when
there are space characters in important pathnames. The instructions
below will remind you of this for several particular items.
You have Maven installed in C:\Program Files\apache-maven-3.2.1
Try to reinstall it to, for example, C:\maven, or change your current variable M2_HOME to C:\PROGRA~1\apache-maven-3.2.1

Answer 2

I had the same issue.
What I did to resolve this is creating M2_HOME & MAVEN_HOME.
Also, edit Path variable value.
New ->C:\Program Files\Apache Software Foundation\apache-maven-3.6.0\bin
where Apache Software Foundation is a folder I created to extract the apache-maven-3.6.0-bin.zip file.
Also, make sure Java is working fine and JAVA_HOME is properly set.

Answer 3

try :
to restart the command prompt
to start the command prompt with run/cmd instead of shift+right-click -"open command window here"
to put the system path between double quote to manage espace character
to replace C:\Program Files\ per C:\PROGRA~1\
edit
this is my own config :
MAVEN_HOME="C:\Program Files\apache-maven-3.2.1"
PATH=XXX;%MAVEN_HOME%\bin;XXX

Answer 4

Hello I had the same problem and I figured it out that I was including some space characters on the "path" next to the ; just by removing the space character I was able to have everything working properly"

Answer 5

this is the settings for my maven.
name: MVN_HOME
value: C:\Program Files\apache-maven-3.2.1
name: path -> add the following value(just the maven part)
value: %JAVA_HOME%\bin;%MVN_HOME%\bin; -> this should have no spaces

Answer 6

I have a very difficult time to solve this problem. It did not work no matter how I set up the environment variables in the control panel of Win7.
My final solution is to set the variables via the cmd.
set M2_HOME "D:\Program Files\Maven\apache-maven-3.3.3"
set M2=%M2_HOME%\bin
set path=%path%;%M2%

Answer 7

I think you have a typo:
change
name: M2
value: %M2_HOME%/bin;
to
name: M2
value: %M2_HOME%\bin;
if it doesn't work change %M2_HOME%\bin with the path.
in this case:
C:\Program Files\apache-maven-3.2.1\bin

Answer 8

Make sure to set the path under the System Variables and not User Variables.

Answer 9

In my case, for reasons I cannot explain, it made a difference to windows 7 if the MAVEN_HOME environment variable was defined in "System Variables" vs "User Variables".
I originally had both JAVA_HOME and MAVEN_HOME as "User Variables" and "Java -version" worked but windows could not find mvn (My path variable looked like this in both cases "Path=C:\Program Files\Java\jre1.8.0_144\bin;E:\Clif\Java\apache-maven-3.6.0\bin;")
Once I changed both Environment variables from "User Variables" to "System Variables" windows was able to find mvn.

Answer 10

I was using %MAVEN_HOME% in the variable path and it was giving problem, even though echo %MAVEN_HOME% command was showing the right path.
I changed it to C:\Program Files\apache-maven-3.6.1\bin in the path (Depends on your version of-course) and it worked like a charm.
