三 启动示例应用程序：

import org.quartz.Scheduler;
  import org.quartz.SchedulerException;
  import org.quartz.impl.StdSchedulerFactory;
  import static org.quartz.JobBuilder.*;
  import static org.quartz.TriggerBuilder.*;
  import static org.quartz.SimpleScheduleBuilder.*;

  public class QuartzTest {

      public static void main(String[] args) {

          try {
              // Grab the Scheduler instance from the Factory
              Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();

              // and start it off
              scheduler.start();

              scheduler.shutdown();

          } catch (SchedulerException se) {
              se.printStackTrace();
          }
      }
  }

日志记录，则所有日志都将发送到控制台，您的输出将如下所示：

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

出现上面的情况就是依赖环境正常的 10个线程 版本是 Quartz Scheduler v.2.3.2 created.
