Not able to use org.ehcache in project

Question

I'm trying to use echache but I can't seem to use in my project. I'm getting the following error:

"Cannot resolve symbol 'ehcache'"

I'm using IntelliJ IDEA and have installed Maven 3.9.4. I've tried mvn clean install and mvn dependency:resolve. After spending around 6+ hours on this, I'm not sure what step to follow now.

Main.java file:

package org.example;

import org.ehcache.*;
public class Main {
    public static void main(String[] args) {
        System.out.println("Hello world!");
    }
}

pom.xml file:

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

            </dependency>
        </dependencies>
    </dependencyManagement>
</project>

mvn clean install output:
