Null pointer execption error while fetching plan using PlanManager.

[Kshitij Korde]

Hi,

Can someone please provide a hint as to what could be going wrong, I am using atlassian-sdk to develop a plugin which displays a new tab when a job containing a specific task (RobotTask) is clicked..

I am getting Null pointer exception error for a very simple thing that I am doing which is fetching the Plan by using the planKey and PlanManager.

Code

64: Plan plan = planManager.getPlanByKey(planKey).

I have a valid plan key which is "TPRO1-TPLAN1-JOB1". Even when I try to use "TPRO1-TPLAN1" as the plan key, I still get the exception...

My code looks like this

public boolean shouldDisplay(Map<String, Object> context) {
    	PlanKey planKey = PlanKeys.getPlanKey((String) context.get("planKey"));
        Plan plan = planManager.getPlanByKey(planKey);
       
        List<TaskDefinition> tasks = plan.getBuildDefinition().getTaskDefinitions();
        for(TaskDefinition task : tasks) {
            if(task.getPluginKey().equals(RobotTask.KEY) ) {
                return true;
            }
        }

        return false;
    }

Below is the stack strace

I found what the problem was, I did not have the constructor to do the initialization.

Below solved it.

public RobotReportViewCondition(final PlanManager planManager){
 this.planManager = planManager;
 }
