mvn command is not recognized as an internal or external command

Question

I am getting the mvn command not recognized as an internal or external command.

I have setup the M2_HOME, JAVA_HOME and added %M2_HOME%/bin to the path variable. All are system variables. Still getting the same problem.

Echoing the variables showing me the correct paths.

Path to Maven: C:\apache-maven-3.1.0\apache-maven-3.1.0

M2_HOME:C:\apache-maven-3.1.0\apache-maven-3.1.0

PATH: Other things,C:\Program Files (x86)\Java\jdk1.7.0_40\bin,C:\apache-maven-3.1.0\apache-maven-3.1.0\bin

and I have restarted my computer twice.

Answer 1

Restart your machine, after setting up your M2_HOME (pointing to you Maven basedir, NOT the bin dir) and PATH (PATH=%M2_HOME%\bin;%PATH%).

Then do:

dir %M2_HOME%\bin\mvn*

If there is a .bat file, it should work under Windows, as it appears to be finding it. If there isn't one, then your paths are not right and you need to make sure your %PATH% variable really points to the correct path to Maven.

Make sure you are using the proper slashes for your OS. Under Windows they're \.

Answer 2

Right click on My Computer >> Properties >> Advanced system settings >> System Properties window will get displayed Under Advanced >> Environment Variables

Click on New to set Environment Variables

Variable name: JAVA_HOME Variable value: C:\Program Files\Java\jdk1.8.0_121

Variable name: M2 Variable value: %M2_HOME%\bin

Variable name: M2_HOME Variable value: C:\Program Files\Apache Software Foundation\apache-maven-3.5.0

Variable name: Path Variable value: %M2_HOME%\bin

Then click on Ok, ok, ok. Now restart you command prompt and check again with “mvn –version” to verify the mvn is running, you may restart your system also.

It's Working...... Enjoy :)

Answer 3

Write the entire maven path into the Environment PATH variable.

Example:

C:\Program Files\apache-maven-3.2.3\bin;

My PATH variable wasn't reading %M2% or %M2_HOME%\bin properly, and therefore I wrote the full path into the PATH variable.

Working.

Answer 4

This is worked for me:

1-download apache-maven-3.3.9-bin.tar.gz file from https://maven.apache.org/download.cgi

2-copy the folder under c:\programfiles

3-set variables as this: M2_HOME ----- C:\Program Files\apache-maven-3.3.9 M2 ----- C:\Program Files\apache-maven-3.3.9

add Path variable to this: ;C:\Program Files\apache-maven-3.3.9\bin

then run the cmd as system admin

it worked.

Answer 5

I also was facing with the same issue still after adding path in environment variable and running it as a normal user in command prompt.

Then I opened command prompt and tried running as "Run as Administrator" and I was able to download all the packages with respect to the project.

Answer 6

Are you trying to reference a user variable in system variables? Try echo %path% and the M2 should have been fully expanded to show the file path to your Maven directory. If it hasn't, then that's the problem.

To fix it, you should create a user variable called PATH and add your %M2% reference into there.

Answer 7

Open Command prompt As "Run As a administrator" and try.

Answer 8

Try %M2_HOME%\bin (\ rather than /)

Answer 9

I faced this problem which kept me busy and buggy for quiet sometime. I was facing the problem (mvn not recognized) after setting up all required environment variables absolutely correctly. So by going by one of the response here, I switched to another version of maven and that fixed the problem.

Not being completely convinced why it worked this way, I then unzipped the problematic-version and updated env-vars which made it work.

The problem was when I initially extracted file from the zip, I modified the directory structure a bit. When you extract the zip, say apache-maven-X.x.x-bin.zip, it creates the folder structure as - "apache-maven-3.5.0-bin\apache-maven-3.5.0..."

In my first attempt I had modified this structure by deleting apache-maven-3.5.0-bin folder and bringing apache-maven-3.5.0 structure one folder up. This was causing the problem.

Windows 10 -

1. Add new variable "M2_HOME" -

2. Update variable "path" -

3. Verify on cmd -

Answer 11

1. Try with echo %path% , if this option doesn't show your M2_HOME and others variable values as directory path, then create a new environment variable lets say PATH, and assign like below:

   PATH=%JAVA_HOME%\bin;%M2_HOME%\bin
   

2. Add this in variable path=.....;%PATH%

3. Now open a new cmd, and try to echo %path%
   it will show all thh system path

Now you can check mvn -version it will solve the problem , if not try to restart the system

P.S. as per doc, you should expend your zip distribution in C:\Program Files\Apache Software Foundation. But ideally it doen't matter

Answer 12

Try setting the path of maven first through command prompt.

setpath.bat Open the cmd from the base window of the batch file.

The rest maven commands can be used once path is set through cmd.

Answer 13

One most important and often overlooked aspect is the %MAVEN_HOME%\bin or %M2_HOME%\bin should be the first thing in the %PATH% environment variable.

Answer 14

I have a stupid comment but someone else will have that issue. I was getting that same error when I was trying to put in ./mvnw clean package and I found out that I had to change it a bit to .\mvnw clean packageand I lived happily ever after.

Answer 15

In your Environement variable :

new system variable:

M2_HOME Your mvn directroy "C:\......\bin"

new user variable:

M2 %M2_HOME%

edit the CLASSPATH by adding %M2%

finally open the cmd and write

path=%CLASSPATH%

enjoy

Answer 16

I had this same error but my problem was I had the following:

M2_HOME = C:\Program Files (x86)\Apache Software Foundation\apache-maven-2.2.1;

Which meant my PATH = %M2_HOME%\bin; (etc)

...became C:\Program Files (x86)\Apache Software Foundation\apache-maven-2.2.1;\bin

i.e. a semicolon was where it shouldn't be.

Which I discovered because Michael Ferry suggested using 'ECHO %PATH%' to see what the actual PATH output was.

Answer 17

I faced similar problems. The article that helped me solve similar issues is by MKyong and is here: ****https://www.mkyong.com/maven/how-to-install-maven-in-windows/**** It is very important to include in maven's path the file that contains the 'bin','boot', 'conf', 'lib' etc. file folders. For example, in my case, the correct path is: C:\Program Files\Apache Software Foundation\maven\apache-maven-3.5.0-bin\apache-maven-3.5.0

Answer 18

I'm using Maven 3+ version. In my case everything was fine. But while adding the M2_HOME along with bin directory, I missed the '\' at the end. Previously it was like: %M2_HOME%\bin , which was throwing the mvn not recognizable error. After adding "\" at the end, mvn started working fine. I guess "\" acts as pointer to next folder. "%M2_HOME%\bin\" Should work, if you missed it.

Answer 19

For me it was not working since I was editing Path variable in "User variable" and adding it under "System variable" made it work. Hope it helps.

Answer 20

For Windows you need to do the following:

1. Windows and type env

2. Open the edit environment panel

3. Click Environment Variables

4. In the system variables section, double click Path

5. In the dialog, create a System Variable under Path like below ->

   MVN_HOME: C:\Users<username>\Documents\Project\Software\apache-maven-3.6.3\bin

6. Open a new command prompt and hit mvn, you should be able to now.

Answer 21

I also faced the issue. But the problem I faced was due to the location name where the maven was stored on system. The path did contain spaces due to which system was not able to reach the path leading to this issue. The issue got resolved for me when I moved the maven to a location which did not contain any spaces.

Answer 22

I had the same problem. But just restarting my computer after setting up the Maven path resolved the issue.

Variable Name: M2_Home Variable Value:C:\Apache\apache-maven-3.3.9

Variable Name: Path Variable Value:C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;%JAVA_HOME%\bin\;%M2_HOME%\bin\

Answer 23

If you've already set the JAVA_HOME and M2_HOME (or MAVEN_HOME in my case) environment variables and added the \bin folder to the Path environment variable and still not working, then this solution could be for you.

Make sure that you have set your variables in the right order, your %JAVA_HOME%\bin folder should be added before the %MAVEN_HOME%\bin just like the shown image

Answer 24

You have written three paths above. The first path (path to maven) should be pointing to the bin directory.

Path to Maven: C:\apache-maven-3.1.0\apache-maven-3.1.0\bin;

Below are right. Above path should be corrected.

M2_HOME:C:\apache-maven-3.1.0\apache-maven-3.1.0;

PATH: Other things,C:\Program Files (x86)\Java\jdk1.7.0_40\bin,C:\apache-maven-3.1.0\apache-maven-3.1.0\bin;
