Custom workflow does not appears in process list. AEM 6.2

Hello:

I have the next problem, I created a custom workflow process and it does not appears on the process list on the dropdown field ( process step) ,

but If I change the version of :

<plugin>

          <groupId>org.apache.felix</groupId>

          <artifactId>maven-scr-plugin</artifactId>

          <version>1.23.0</version>

  </plugin>

from 1.23.0 to 1.20.0 this appears correctly and works.

I tried this answer from this forum but it does not work for me Custom Workflow Step Not Showing up in Process List Dropdown

I tried this link also AEM Developer Learning : July 2017​  like possible solution ( it is the most recent article I have found) but this does not work for maven-scr-plugin version 1.23.0

We need to keep maven-scr-plugin on version 1.23.0 to guarantee the stability of our project.

Here is an example of Workflow process we are using.

import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Properties;
import org.apache.felix.scr.annotations.Property;
import org.apache.felix.scr.annotations.Service;
import org.osgi.framework.Constants;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.day.cq.workflow.WorkflowException;
import com.day.cq.workflow.WorkflowSession;
import com.day.cq.workflow.exec.WorkItem;
import com.day.cq.workflow.exec.WorkflowProcess;
import com.day.cq.workflow.metadata.MetaDataMap;
@Component
@Service
@Properties({ 
    @Property(name = Constants.SERVICE_DESCRIPTION, value = "Testing workflow"),
    @Property(name = Constants.SERVICE_VENDOR, value = "TEST"),
    @Property(name = "process.label", value = "Testing workflow test") })
public class WorkFlowTest implements WorkflowProcess{
    private static final Logger LOG = LoggerFactory.getLogger(WorkFlowTest.class);
    
    @Override
    public void execute(WorkItem arg0, WorkflowSession arg1, MetaDataMap arg2) throws WorkflowException {
        // TODO Auto-generated method stub
        LOG.info("Hellooooooooooooooooooo testing !!!!!!!");
    }
}

There is any way to implement a custom Workflow Process without changing the version of maven-scr-plugin?

Thank you.

Finally I figured out what was missing:

Was missing add the line @Property(name = "service.pid", value = "com.test.yourpackage.name.WorkFlowTest"), so the Java class will be like it is:

  1. import org.apache.felix.scr.annotations.Component; 
  2. import org.apache.felix.scr.annotations.Properties; 
  3. import org.apache.felix.scr.annotations.Property; 
  4. import org.apache.felix.scr.annotations.Service; 
  5. import org.osgi.framework.Constants; 
  6. import org.slf4j.Logger; 
  7. import org.slf4j.LoggerFactory; 
  8.  
  9. import com.day.cq.workflow.WorkflowException; 
  10. import com.day.cq.workflow.WorkflowSession; 
  11. import com.day.cq.workflow.exec.WorkItem; 
  12. import com.day.cq.workflow.exec.WorkflowProcess; 
  13. import com.day.cq.workflow.metadata.MetaDataMap; 
  14.  
  15. @Component 
  16. @Service 
  17. @Properties({  
  18.     @Property(name = Constants.SERVICE_DESCRIPTION, value = "Testing workflow"), 
  19.     @Property(name = Constants.SERVICE_VENDOR, value = "TEST"),
  20.     @Property(name = "service.pid", value = "com.test.yourpackage.name.WorkFlowTest") 
  21.     @Property(name = "process.label", value = "Testing workflow test") }) 
  22.  
  23.  
  24. public class WorkFlowTest implements WorkflowProcess{ 
  25.  
  26.     private static final Logger LOG = LoggerFactory.getLogger(WorkFlowTest.class); 
  27.      
  28.     @Override 
  29.     public void execute(WorkItem arg0, WorkflowSession arg1, MetaDataMap arg2) throws WorkflowException { 
  30.         // TODO Auto-generated method stub 
  31.         LOG.info("Hellooooooooooooooooooo testing !!!!!!!"); 
  32.     } 
  33.  
  34. } 

The solution was the line number 20.

Did you try generating your workflow step by using Maven 10 Archetype - which is the recommended version to use for 6.2.

I will test that too right now on AEM 6.2 and post back my findings.

I just tested our article on 6.2 and it works -- see: Adobe Experience Manager Help | Creating custom AEM workflow steps that send email messages

Hi,

Eventually it is working  without property - service.pid as per the article. We have tested article many times.

Also, We will add that line no 20 in HELPX article when smacdonald2008 back to work!!

Thanks,

Ratna.
