Declaring new cron jobs

<?php

namespace Drupal\example_module\Plugin\SimpleCron;

use Drupal\simple_cron\Plugin\SimpleCronPluginBase;

/**
 * Example cron job implementation.
 *
 * @SimpleCron(
 *   id = "example_cron_job",
 *   label = @Translation("Example cron job", context = "Simple cron")
 * )
 */
class ExampleCron extends SimpleCronPluginBase {

  /**
   * {@inheritdoc}
   */
  public function process(): void {
    // Cron job process implementation.
  }

}
