Not able to use Spin

I am not able to use Spin Library on my IntelliJ IdeA.

I created a new Maven project.
Copied this to my pom.xml file

<dependencies>
  <dependency>
    <groupId>org.camunda.spin</groupId>
    <artifactId>camunda-spin-core</artifactId>
  </dependency>

  <dependency>
    <groupId>org.camunda.spin</groupId>
    <artifactId>camunda-spin-dataformat-all</artifactId>
  </dependency>

Then I imported changes.

After adding and running a simple program -

import static org.camunda.spin.Spin.*;
import static org.camunda.spin.DataFormats.*;
 
public class app {
    public static void main(String... args)
    {
        System.out.println("Hello");
    }
}

The Error is -

    java: package org.camunda.spin does not exist

Why haven’t you provided the versions of dependencies? Do you have something in dependencyManagement section of your POM?
