3. Verify the installation

Open the command line window and enter mvn -v. If the Maven version information is successfully displayed, the installation is successful.

3. Configure Maven’s settings.xml

Maven’s configuration file settings.xml is located in Maven’s conf folder. By editing the settings.xml file, we can configure Maven's global settings, warehouse, proxy, etc. The following is a simple settings.xml configuration example:

<?xml version="1.0" encoding="UTF-8"?>

<settings>
    <mirrors>
        <mirror>
            <id>aliyun</id>
            <mirrorOf>*</mirrorOf>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
        </mirror>
    </mirrors>
    
    <profiles>
        <profile>
            <id>jdk-1.8</id>
            <activation>
                <activeByDefault>true</activeByDefault>
                <jdk>1.8</jdk>
            </activation>
            <properties>
                <maven.compiler.source>1.8</maven.compiler.source>
                <maven.compiler.target>1.8</maven.compiler.target>
                <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
            </properties>
        </profile>
    </profiles>
</settings>

4. Create a simple Maven project
