Can't find symbol getWorkflowManager() in com.atlassian.jira.ComponentManager

Steven Liu3
Steven Liu January 28, 2016

Hi:

  1. I created a JIRA Rest service plugin using the following link:
    https://developer.atlassian.com/docs/atlassian-platform-common-components/rest-api-development/developing-a-rest-service-plugin
  2. This plugin works as expected, then I want to customize this plugin by writing some code. 

  3. Added the following dependencies into pom.xml.

    <dependency>
			 <groupId>com.atlassian.jira</groupId>
			 <artifactId>jira-api</artifactId>
			 <version>${jira.version}</version>
			 <scope>provided</scope>
</dependency>
<dependency>
			<groupId>com.atlassian.jira</groupId>
			<artifactId>jira-core</artifactId>
			<version>${jira.version}</version>
			<scope>provided</scope>
</dependency>

  4. Added one line of code for getting workflow manager

    package com.atlassian.plugins.enterprisetester.rest;
import com.atlassian.plugins.rest.common.security.AnonymousAllowed;
import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.workflow.WorkflowManager;
import com.atlassian.jira.workflow.JiraWorkflow;
import com.atlassian.jira.issue.Issue;

/**
 * A resource of message.
 */
@Path("/message")
public class EnterpriseTesterRestResource {
    @GET
    @AnonymousAllowed
    @Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
    public Response getMessage()
    {
		//Getting workflow manager 
		WorkflowManager workflowManager = ComponentManager.getInstance().getWorkflowManager();
		
		return Response.ok(new EnterpriseTesterRestResourceModel("Hello World")).build();
    }
}

  5. I got the following error: 

    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5:compile (default-compile) on project RestService: Compilion failure

  6. I don't know why method getWorkflowManager() can't be resolved. 

Cheers

Steven

ComponentManager has been depriated since use ComponentAccessor instead. In your case:

WorkflowManager workflowManager = ComponentAccessor.getWorkflowManager();

Hi Vasiliy:

I tried your code:

WorkflowManager workflowManager = ComponentAccessor.getWorkflowManager();

I can compile the above code using atlas-compile.

After running it using atlas-run, I got the following error when access the resource

HTTP Status 404 - NoOpServlet received an unexpected request. More information is available in the log file.

Found some internal errors about the "missing requirement [50.0] osgi.wiring.package;". I don't know what it is.

There are 2 options:

  1. Erroe in code. Could be tested via Script Console provided by Script Runner console
  2. Erros into plugin compilation. I would recommend to use Intellj IDEA to built plugins.

Hi Vasiliy:

The difference between working and non-working one is the line you told me to add:

WorkflowManager workflowManager = ComponentAccessor.getWorkflowManager();

I've tried my code in Script Console, it works fine. The error I got is not a compilation error.

If you can have a look at the error log I attached, then you will have a cue. I don't want to paste the same error log again and again. 

Cheers

I can compile the above code using atlas-compile.

After running it using atlas-run, I got the following error when access the resource

HTTP Status 404 - NoOpServlet received an unexpected request. More information is available in the log file.

Then I tried a different approach to get workflow manager using ComponentAccessor

package com.atlassian.plugins.enterprisetester.rest;
import com.atlassian.plugins.rest.common.security.AnonymousAllowed;
import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.workflow.WorkflowManager;
import com.atlassian.jira.workflow.JiraWorkflow;
import com.atlassian.jira.issue.Issue;

/**
 * A resource of message.
 */
@Path("/message")
public class EnterpriseTesterRestResource {
    @GET
    @AnonymousAllowed
    @Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
    public Response getMessage()
    {
		
		WorkflowManager workflowManager = ComponentAccessor.getWorkflowManager();
       	JiraWorkflow workflow = workflowManager.getWorkflow("Bug Workflow for Project STPJ");
		String workflowName = workflow.getName();
 
			
		return Response.ok(new EnterpriseTesterRestResourceModel("Hel")).build();
    }
}

I got the following error (ComponentAccessor has not been initialised) :

Running ut.com.atlassian.plugins.enterprisetester.MyComponentUnitTest
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.047 sec

java.lang.IllegalStateException: ComponentAccessor has not been initialised.
This is not expected to occur on a production system.
Developers that encounter this message within a unit test
should use n MockitoMocksInContainer rule to initialize mockito and ComponentAccessor.
For more detailed explanation read the documentation
for MockComponentWorker in the jira-tests artifact for more information
about what causes this error and how to address it.
