A friend asked me to make a minecraft plugin for them, so I need to install Maven. I've installed the following user variables as instructed by the tutorial.

  • JAVA_HOME -- Value: C:\Program Files\Java\jdk1.8.0\bin

  • M2_HOME -- Value: C:\Minecraft Plugin Development\apache-maven-3.2.1

  • M2 -- Value: %M2_HOME%\bin

I've also added ;%M2% to my system PATH variable as instructed. My problem is running the mvn --version command to verify if it's installed. I tried to also set the variables using SET M2, SET M2_HOME, SET JAVA_HOME, and SET PATH. I've attempted that as instructed by an answer on

windows 7 maven 2 install

It responds to me when I try setting it in Command Propmpt by saying Environment variable (Name) not defined. How would I successfully run mvn --version?

Thanks for reading.

EDIT in response:

So I went to the bin directory like jayalalk said, I ran it and it recognized the command. However, it said

Error: JAVA_HOME not found in your environment. Please set the JAVA_HOME variable in your environment to match the location of your java installation.

I checked and I have declared JAVA_HOME in both User and System variables to the correct location of my java installation, C:\Program Files\Java\jdk1.8.0\bin.

Also, this is my system PATH variable value: C:\Program Files\Java\jdk1.8.0\bin;%M2% Is there anything wrong with that?

    Just try to go to maven folder and its bin folder from command line, and try mvn --version and verify first. If works then you have some problem with path setting, then type SET PATH in command line and verify your path is added in PATH variable – jayalalk May 14 '14 at 00:38

It seems set JAVA_HOME = "C:\Program Files\Java\jdk1.8.0" and path = %JAVA_HOME%\bin;%M2%.

  • Umm.. I kinda just realized I might have deleted my entire path variable awhile back.. My whole path variable is currently `%JAVA_HOME%\bin;%M2%`.. Should I default it to the original then add this on? And if so, what is the original? – Aetharius May 14 '14 at 01:34
