3. Maven environment variable configuration
Turn on environment variables
The "Environment Variables" interface is divided into upper and lower parts. The upper part is the setting of "user variables of so-and-so", which is for the account you are currently logged into the computer; the lower part is the setting of system variables, which is for this A computer is equivalent to all accounts. For your own computer, it is recommended to configure it directly in the "System Variables" in the following section. Let’s take system variables as an example to explain:
a. Create a new MAVEN_HOME variable in the system variables and set the variable name and variable value.
The MAVEN_HOME variable stores maven-related path configuration
b. Configure MAVEN_HOME into the system environment variable path
Double-click the path variable, create a new parameter, enter %MAVEN_HOME%\bin and click OK.
The role of the environment variable path: Provides the executable file path of the command in the Windows command line. When we type the command in the command line, based on the path value in the environment variable, we find the corresponding command executable file for execution. Simply put, it is the directory parameter configured in path, which can be used in any directory on the command line.
After completing the above operations, click OK to save and close the configuration interface.
Type mvn -aversion in the cmd window and press Enter. If the following version number appears, it means that maven is installed successfully.

a. Configuration of local warehouse
Create a folder in the D drive and name it maven_repository
Open the maven installation directory and select the setting.xml file in the conf folder
Check whether the setting has been successful. After saving, enter the console input:
mvn help:system Then open the folder you just created. If a file is generated in it, it means the modification is successful.
b. Modify Maven’s download image address to Alibaba source
After installing Maven, you must promptly modify the image address downloaded by Maven. It is best to change it to a domestic download image, such as Alibaba Cloud Central Warehouse and Huawei Cloud Central Warehouse.
Also open the setting.xml file in the conf folder, find </mirrors>, and add the following code to the previous line of </>.
<mirror>
<id>alimaven</id>
