Maven：未找到 mvn 命令

Question

I set the following system veriables (OS = Vista):

M2_HOME = C:\Program Files\Maven 
M2 = %M2_HOME%\bin 
path = %M2% 

If i run mvn -- version I get:

mvn: command not found

Anyone have any idea why this could be? Thanks.

Answer 1

If you are on windows, what i suppose you need to do set the PATH like this:

SET PATH=%M2%

furthermore i assume you need to set your path to something like C:...\\apache-maven-3.0.3\\ cause this is the default folder for the windows archive. On the other i assume you need to add the path of maven to your and not set it to only maven so you setting should look like this:

SET PATH=%PATH%;%M2%

Answer 2

I tried solutions from other threads. Adding M2 and M2_HOME at System variables, and even at User variables. Running cmd as admin. None of the methods worked.

But today I added entire path to maven bin to my System variables "PATH" (C:\\Program Files (x86)\\Apache Software Foundation\\apache-maven-3.1.0\\bin) besides other paths, and so far it's working good. Hopefully it'll stay that way.

Answer 3

I followed this tutorial: How to install Maven on Windows

But running mvn -version , I still got:

mvn: command not found

So, I closed the current git window, and opened a new one. Everything went okay :)

Answer 4

Maven setup:

a. install maven from https://maven.apache.org/download.cgi

b.unzip maven and keep in C drive.

c. Set MAVEN_HOME in system variable.

d. Set path for maven

Answer 5

1. Run ' path ' in command prompt and ensure that the maven installation directory is listed.
2. Ensure the maven is installed in 'C:\\Program Files\\Maven'.

Answer 6

I think the problem is with the spaces. I had my variable at the System variables but it didn't work. When I changed variable Progra~1 = 'Program Files' everything works fine.

M2_HOME C:\Progra~1\Maven\apache-maven-3.1.1

I also moved my M2_HOME at the end of the PATH(%M2_HOME%\\bin) I'm not sure if this has any difference.

Answer 7

mvn -version

export PATH=$PATH:/opt/apache-maven-3.6.0/bin

Answer 8

I think the tutorial passed by @emdhie will help a lot. How install maven

But, i followed and still getting mvn: command not found

I found this solution to know what was wrong in my configuration:

I opened the command line and called this command:

../apache-maven-3.5.3/bin/mvn --version

After that i got the correct JAVA_HOME and saw that my JAVA_HOME was wrong.

Hope this helps.
