4. Configure the system environment variables:

In order for subsequent MAVEN version changes to not affect changes in our system environment variables, we first set up a soft connection for apache-maven-3.0.3

Ln-s apache-maven-3.0.3 maven

Configure MAVEN Home directory: Export m2_home=/usr/local/apache-maven-3.0.3

Configure the bin directory under your command-line path: Export Path=/usr/local/apache-maven-3.0.3/bin

Or add the above two configurations directly to the configuration file: ~/.bash_profile (~/.ZSHRC)

At the same time, you can also add the above two configuration M2_home,path to a script, so each time you log in to run this script/.bash_login

5. Verify the installation results mvn-v, after success, you can use MAVEN on the command line.
