The custom scheduler is not working after upgrading from 7.4 U62 to U90

Issue

• We have written a scheduler which works perfectly in 7.4 U62, but when we updated our bundle to 7.4 U90, it is not working. 

 

Environment

• Liferay DXP 7.4

 

Resolution

• Due to the changes by LPS-176754, please adapt your code to make it work in 7.4 U90. Below is a guideline you can refer when adapting the code. As this involves customization, what Liferay Support can help is limited. Please feel free to contact your Sales Representative for further assistance from Liferay Global Services team.
• 1. You can compare the previous code to the current one and make necessary changes.

  - Current code
   
    2. How to replace your xxxMessageListener.java with an xxxSchedulerJobConfiguration.java
   
  

  ---

  Step 1 - Copy the old file
  Copy the xxxMessageListener.java file into xxx/internal/scheduler folder
  For example, SyncMaintenanceMessageListener.java would move from com/liferay/sync/internal/messaging/ to com/liferay/sync/internal/scheduler/
   
  Step 2 - Rename the old file
  Rename the xxxMessageListener.java file to xxxSchedulerJobConfiguration.java
  For example SyncMaintenanceMessageListener.java to SyncMaintenanceSchedulerJobConfiguration.java
   
  Step 3 - Change the package in the file
  package com.liferay.xxx.internal.messaging; changes to package com.liferay.xxx.internal.scheduler;
  For example, package com.liferay.sync.internal.messaging; to package com.liferay.sync.internal.scheduler;
   
  Step 4 - Add the @Component annotation
  Remove the old annotation. Add the new one:
  @Component(service = SchedulerJobConfiguration.class)
   
  Step 5 - Import and Implement the SchedulerJobConfiguration interface
  Add the import com.liferay.portal.kernel.scheduler.SchedulerJobConfiguration; line
  Your xxxSchedulerJobConfiguration implements SchedulerJobConfiguration
  For example, public class SyncMaintenanceSchedulerJobConfiguration 
implements SchedulerJobConfiguration {
   
  Step 6 - Override UnsafeRunnable
  Import the class:
  import com.liferay.petra.function.UnsafeRunnable;
  Override the method:
  @Override 
public UnsafeRunnable<Exception> getJobExecutor() {
   
  Step 7 - Override TriggerConfiguration
  import the class:
  import com.liferay.portal.kernel.scheduler.TriggerConfiguration;
  Override the method:
  @Override 
public TriggerConfiguration getTriggerConfiguration() {
   
  Step 8 - Modify the activate method
  Modify the method to only include the ConfigurableUtil method. For example:
  @Activate 
protected void activate(Map<String, Object> properties) { 
_assetPublisherWebConfiguration = ConfigurableUtil.createConfigurable( 
AssetPublisherWebConfiguration.class, properties); 
}
   
  Step 9 - Remove the unused classes and their imports
  
  import com.liferay.portal.kernel.messaging.BaseMessageListener;
import com.liferay.portal.kernel.messaging.DestinationNames;
import com.liferay.portal.kernel.messaging.Message;
import com.liferay.portal.kernel.scheduler.SchedulerEngineHelper;
import com.liferay.portal.kernel.scheduler.SchedulerEntry;
import com.liferay.portal.kernel.scheduler.SchedulerEntryImpl;
import com.liferay.portal.kernel.scheduler.Trigger;
import com.liferay.portal.kernel.scheduler.TriggerFactory;
   
  Step 10 - Delete the xxxMessageListener.java file
