Set Up Maven Environment in IntelliJ IDEA

To configure the Maven environment variables, you can follow these steps:

1. Download and install Maven. Get the Maven distribution suitable for your operating system from the Apache Maven website (https://maven.apache.org/) and follow the installation instructions.
2. Open the command line terminal and type in the command mvn -version to confirm that Maven has been successfully installed.
3. Open the environment variable configuration interface in the system. On Windows systems, you can right-click on “Computer” or “My Computer”, choose “Properties”, then click on “Advanced System Settings”, and then click on the “Environment Variables” button. On Mac or Linux systems, you can edit the ~/.bashrc or ~/.bash_profile file.
4. Add a new variable in the system or user environment variables. The variable name is M2_HOME, and the variable value is the installation directory of Maven. For example, if Maven is installed in C:\apache-maven-3.8.4, then the variable value should be C:\apache-maven-3.8.4.
5. In the system or user environment variables, edit the Path variable to add the Maven bin directory. For example, in Windows systems, add ;%M2_HOME%\bin to the end of the Path variable.
6. Save and close the environment variable configuration interface.
7. In the command line terminal, type the command “mvn -version” to confirm that Maven’s environment variables have been configured successfully.

By doing this, you have successfully set up the Maven environment variables. You can now use Maven commands directly in the command line terminal to build and manage projects.
