Solution 1

1. Download Maven at here.

2. Unzip, for example: C:\tools\

3. Press Windows+R, type systempropertiesadvanced, press Enter

4. Set environment: MAVEN_HOME = C:\tools

Add to PATH environment variable: ;%MAVEN_HOME%\bin

5. Close all

6. Call cmd, run command:

   mvn -v

Solution 2

1. Open PowerShell or terminal and run java -version to make sure Java is installed

2. Go to Apache Maven's download page and, if you're using Maven just as a tool, download the "Binary zip archive" from the link

3. Place the downloaded file in the folder where you have all your Java related things (in my case, C:\Program Files\Java)

4. Right click in that file and "Extract here". Then, delete the .zip file.

if we open that new folder we should have something like

5. Go to advanced system settings (by searching for that term or right clicking in "This PC" > Properties) and "Environment variables".

6. Define a new System Environment Variable by clicking New and

Variable Name: M2_HOME

VARIABLE VALUE: C:\Program Files\Java\apache-maven-3.6.3

7. Append the bin subdirectory of the folder C:\Program Files\Java\apache-maven-3.6.3 into the PATH variable

8. Restart your computer and then run mvn --version.

That's it, you have now Maven installed in Windows 10.

Solution 3

Add system variable JAVA_HOME (with address JDK) and M2_HOME with route directory maven.

Let's clean everything, then install everything from scratch.

Remove MAVEN_HOME really not needed only the bin folder into PATH that's it. And of course JAVA_HOME setting to JDK...and than mvn --version...BTW: Use for download this: maven.apache.org/download.cgi

[Sudha Velan]

open cmd prompt and type "mvn -version".You will get maven details.If you get that then maven home is set.

@DoNhuVy, I think there is type of ENV variable, it should be %MAVEN_HOME%\bin

[alelom]

Can you clarify point 7? What do you mean append? Why not creating directly the variable with the correct path in point 6?

[Tiago Martins Peres]

@alexlomba87 you can do that too yes!

Please provide additional details in your answer. As it's currently written, it's hard to understand your solution.

This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker.

Worked for me on Windows 11 as well.
