Getting Null pointer Exception while trying to get the agent list

Hello,
I am trying to build a bamboo REST plugin module for getting an agent list
Here is my code


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.bamboo.buildqueue.manager.AgentManager;
import com.atlassian.bamboo.v2.build.agent.BuildAgent;
import com.atlassian.util.concurrent.NotNull;

import java.util.ArrayList;
import java.util.List;


/**
 * A resource of message.
 */
@Path("/AgentManagement")
public class AgentManagement {
    private AgentManager agentManager;

    public AgentManager getAgentManager() {
        return agentManager;
    }

    private List<AgentManagementModel> agentManagementModels = new ArrayList<AgentManagementModel>();

    @GET
    @AnonymousAllowed
    @Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_JSON})
    public Response getMessage() {

try {
    List<BuildAgent> remoteAgents = new ArrayList<BuildAgent>(agentManager.getAllRemoteAgents());
            AgentManagementModel agentManagementModel = new AgentManagementModel();
            for (BuildAgent RemoteAgent : remoteAgents) {
                agentManagementModel.setAgentName(RemoteAgent.getName());
                agentManagementModel.setAgentStatus(String.valueOf(RemoteAgent.isBusy()));
                agentManagementModels.add(agentManagementModel);
            }
            return Response.ok(new AgentManagementModel(agentManagementModels)).build();
        }catch(Exception e){
return Response.ok(new AgentManagementModel(e.toString())).build();
        }
    }
    public void setAgentManager(AgentManager agentManager) {
        this.agentManager = agentManager;
    }
}


But it throughs null pointer Exception. at this line
List remoteAgents = new ArrayList(agentManager.getAllRemoteAgents());

Anyone have an idea on it
Thanks in advance

Your class works fine for me with Bamboo 6.3.0 and agentManager is not null.

Are there any exceptions in the bamboo logs from when you install your plugin or when you call the rest endpoint aside from the NullPointerException on agentManager? If not could you post the stack trace of the NullPointerException you’re getting?

Hi,
Thanks for your reply, I am using bamboo version 6.8.0. And I am testing it with same development bamboo server by installing a few remote agents to it.
I just commented my exception handling(try catch block) and this is the stack trace of my exception I am getting

Thanks in advance

Is there nothing else in Bamboo’s logs? It seems like Spring must be failing to inject the AgentManager object for some reason, I would think there would be some explanation in the atlassian-bamboo.log file.

Hi lorenzo,
I checked in the logs too but no use. In log also it just displays the null pointer exception for my API call and not any root cause.
And you are correct I am too suspected that Spring must be failing to inject the AgentManager object for some reason.

@lorenzo.babbage is there is something I need to add in the atlassian-plugin.xml file for it to auto-inject Agentmanager?

could you please share me your pom.xml and atlassian-plugin.xml
