Custom Workflow Step Not Showing up in Process List Dropdown

[tw99384403]

Hi,

I have written an OSGI service that implements com.adobe.granite.workflow.exec.WorkflowProcess.  The bundle deploys and is in "active" state with no errors.  When trying to create a "process step" within OSGI workflow editor, my service does not show up in the process list (see attached screenshot).  The annotations I am using in my service class are pasted below, along with relevant errors from the error log.  What am I doing wrong?

@Component
@Service
@Properties({
@Property(name = Constants.SERVICE_DESCRIPTION, value = "Alfresco CMIS Connector"),
    @Property(name = Constants.SERVICE_VENDOR, value = "Adobe"),
    @Property(name = "process.label", value = "Store PDF into Alfresco repository") 
})

Try this

@Component
@Service
public class AlfrescoConnector implements WorkflowProcess {
    @Property(value = "Alfresco CMIS Connector.")
    static final String DESCRIPTION = Constants.SERVICE_DESCRIPTION;
    @Property(value = "Adobe")
    static final String VENDOR = Constants.SERVICE_VENDOR;
    @Property(value = "Store PDF into Alfresco repository")
    static final String LABEL="process.label";
    
    @Override
    public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap metaDataMap) throws WorkflowException {
    
        ......YOUR LOGIC HERE......
        }
    }

Thanks.  I actually followed that tutorial.

Tried the suggested alternative form of property annotations and still not showing up in process list.  Has anyone seen that specific error?  I am logged in as admin, so can't be a permissions problem.

When you followed the article - did you see the action in the drop-down?

I figured out the issue.  Problem was that the workflow dependency defined in my maven project file did declare a scope, i.e. it used the default maven 'compile' scope.  By adding 'provided' scope, as shown below, my service now shows up in process list of "process step".

        <dependency>
            <groupId>com.adobe.granite</groupId>
            <artifactId>com.adobe.granite.workflow.api</artifactId>
            <version>1.0.10</version>
            <scope>provided</scope>
        </dependency>
