That is not how you build scheduled jobs in 7.4. See https://liferay.dev/blogs/-/blogs/liferay-7-4-scheduled-tasks

Schedular class in liferay 7.4 issue

2024-04-23T16:11:25Z

Hello everyone,

I have created a schedular class in liferay 7.4. When i deployed the module in the server getting the issue. Provided below the code and issue details for reference.

Code:
public class TestScheduler extends BaseMessageListener {
   private static Log _log = LogFactoryUtil.getLog(TestScheduler.class);
   @Override
   protected void doReceive(Message message) throws Exception {
       _log.info("------->Safety Scheduler started successfuly<--------");
   }
   @Activate
   @Modified
   protected void activate() {
       Class<?> clazz = getClass();
       String className = clazz.getName();
       Trigger trigger = _triggerFactory.createTrigger(clazz.getName(), clazz.getName(), null, null, "0 0 20 1 1/1 ? *");
       SchedulerEntry schedulerEntry = new SchedulerEntryImpl(className, trigger);
       _schedulerEngineHelper.register(this, schedulerEntry, DestinationNames.SCHEDULER_DISPATCH);
   }
   @Deactivate
   protected void deactivate() {
       _schedulerEngineHelper.unregister(this);
   }
   @Reference(target = ModuleServiceLifecycle.PORTAL_INITIALIZED, unbind = "-")
   protected void setModuleServiceLifecycle(ModuleServiceLifecycle moduleServiceLifecycle) {
   }
   @Reference(unbind = "-")
   protected void setSchedulerEngineHelper(SchedulerEngineHelper schedulerEngineHelper) {
       _schedulerEngineHelper = schedulerEngineHelper;
   }
   @Reference(unbind = "-")
   protected void setTriggerFactory(TriggerFactory triggerFactory) {
   }
   private SchedulerEngineHelper _schedulerEngineHelper;
   @Reference(unbind = "-")
   private volatile TriggerFactory _triggerFactory;
}

Issue:
