To install Apache Maven on Windows, you just need to download the Maven’s zip file, and Unzip it to the directory you wish to install, and configure the Windows environment variables.
Tools Used :
  1. JDK 1.7
  2. Maven 3.2.2
  3. Windows 8
Note
Maven 3.2 requires JDK 1.6 or above, while Maven 3.0/3.1 requires JDK 1.5 or above

1. JDK and JAVA_HOME

Make sure JDK is installed, and “JAVA_HOME” variable is added as Windows environment variable.
install-maven-on-windows-1

2. Download Apache Maven

Visit Maven official website, download the Maven zip file, for example : apache-maven-3.2.2-bin.zip. Unzip it to the folder you want to install Maven.
Assume you unzip to this folder – C:\Program Files\Apache\maven
install-maven-on-windows-2
Note
That’s all, just folders and files, installation is NOT required.

3. Add M2_HOME and MAVEN_HOME

Add both M2_HOME and MAVEN_HOME variables in the Windows environment, and point it to your Maven folder.
install-maven-on-windows-3
M2_HOME or MAVEN_HOME
Maven document said add M2_HOME only, but some programs still reference Maven folder with MAVEN_HOME, so, it’s safer to add both.

4. Add To PATH

Update PATH variable, append Maven bin folder – %M2_HOME%\bin, so that you can run the Maven’s command everywhere.
install-maven-on-windows-4

5. Verification

Done, to verify it, run mvn –version in the command prompt.
