Maven isn't installing correctly

Question

I am trying to install maven v3.5.4 onto my computer and whenever I try the 'mvn -version' command, I get

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

I have looked up multiple tutorials on how to do this, and they are giving nearly the same information. Add system variables M2 and M2_HOME, then append a directory to the Path system variable. I have the System Variables configured to the following:

M2:

Name: M2
Value: C:\Program Files\Apache\maven\bin

M2_HOME:

Name: M2_HOME
Value: C:\Program Files\Apache\maven

MAVEN_HOME:

Name: MAVEN_HOME
Value: C:\Program Files\Apache\maven

Path:

Name: Path
Value: %M2_HOME%\bin;%JAVA_HOME%\bin

I have seen people saying that there should be a .exe or .bat file inside the bin directory. I do not have any of these. I only have 4 files inside this folder.

This could perhaps be the issue. The path to my Maven directory is: I have the following maven related system variables:

And my Path variable is:

I'm not sure how to fix this issue so if anyone knows, please let me know.

`%M2_HOME%\bin %JAVA_HOME%\bin` ?? is it by mistake or missing `;` — Shubhendu Pramanik, Jul 31 '18 at 05:59
have you added your `JAVA_HOME` variable linked to your jdk directory? Also you should setup `MAVEN_HOME` with value `C:\Program Files\Apache\maven` to avoid troubles. — Mochuelo, Jul 31 '18 at 06:02
Yes, JAVA_HOME is added as a System Variable. I tried adding MAVEN_HOME and testing the mvn command still gives the error. — Plasma, Jul 31 '18 at 06:07
Can you navigate into your maven/bin folder and type "mvn --version"? — T A, Jul 31 '18 at 06:34
@Plasma There is no .exe or .bat file in my '/bin' folder. I am using version 3.5.4 like you. The bin folder looks fine. I'm confident that a fresh installation of Maven will fix your problem. If this doesn't work either, try restarting your computer too. — Soutzikevich, Jul 31 '18 at 08:05
@TA I tried navigating there and I'm still getting the same error. — Plasma, Aug 01 '18 at 20:49
@P.Soutzikevich I restarted my computer after a fresh installation and it still doesn't seem to be working. — Plasma, Aug 01 '18 at 20:55
in all of this, are you closing the command line after you do some changes to the PATH? The new changes for system variables are not beeing reflected to the console until you restart it. — Ermal, Nov 23 '19 at 10:38

Add a variable MAVEN_HOME like:

Name: MAVEN_HOME

Value: C:\Program Files\apache-maven-3.3.9\bin

In your case, the M2_HOME path is not correct. Hence It must not be working. Try to give the correct path to the bin folder.

I added the variable MAVEN_HOME however I added it as C:\Program Files\Apache\maven and not the bin directory. I added the bin directory and it still does not seem to be working. Also, I have maven installed to C:\Program Files\Apache\maven not C:\Program files\apache-maven-3.3.9 – Plasma Jul 31 '18 at 06:19
@Plasma path name is not issue. It was just for an example. maven is also correct however you need to provide path till bin and It must work. – Nitin Bisht Jul 31 '18 at 06:34
@Plasma Secondly What is the error you are getting after adding path till bin?? – Nitin Bisht Jul 31 '18 at 06:36
@Plasma Are you doing this in system variable or user variable? – Nitin Bisht Jul 31 '18 at 06:37
I adding this as a system variable and not a user variable. Also, the error I'm getting is in the question. – Plasma Aug 01 '18 at 20:40
@Plasma add this in user variable and let me know then. – Nitin Bisht Aug 02 '18 at 04:04
I did. And in the reply, I said I did. – Plasma Aug 03 '18 at 21:38
@Plasma paste the url of screenshoot of your user variable path. Let me check where things are going wrong. – Nitin Bisht Aug 04 '18 at 04:54
I put the screenshot into the question. – Plasma Aug 04 '18 at 17:58
@Plasma screenshot of your user variable settings. – Nitin Bisht Aug 04 '18 at 18:01
I don't use user variables, I'm using System Variables for this and, I put screenshots of those in the question. – Plasma Aug 05 '18 at 18:15

First you have to download maven from here, preferably the latest version and install it.

Then, you have to set the Path variable for Maven.

Go to Start and search for 'Edit the system environment variables'. Choose the environment variables option and like you do in the example you provided, leave M2_HOME as you have it, delete M2 and change the one in your path to: %M2_HOME%\bin\;

Also, please make sure that you are editing the system environment variables.

As I it says on the download page of the version you are trying to install: "Maven 3.3+ require JDK 1.7 or above to execute". So make sure you have the right version of java.

If this does not work, then I don't think someone on Stack-Overflow can help.

I have done this and it doesn't seem to be working. And yes I am editting System environment variables and not User variables. – Plasma Jul 31 '18 at 06:17
Have you tried uninstalling and reinstalling maven? If you are using Windows, then use this [link](http://www-eu.apache.org/dist/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.zip). It's the current stable version. – Soutzikevich Jul 31 '18 at 07:57
@Plasma I have updated my answer. The problem might be the version of Java you are using. You need java 7 or later – Soutzikevich Jul 31 '18 at 08:02
I'm using Java 8 and I tried uninstalling and reinstalling maven using your link and I am still getting the same error. – Plasma Aug 01 '18 at 20:47
