How to invoke/start a plan programatically with Bamboo 5.11?

I've tried this approach in the link below but it won't compile due to version changes.

Hi Anna, I don't know what went wrong with that program. We would need more info on that.

But how about using REST API to trigger a plan?

In my Bamboo 5.15, I was able to trigger a test plan by just running a curl command like below.

curl --user username:password -X POST http://yourbamboohost:8085/rest/api/latest/queue/PROJ-PLA

where PROJ is your project name and PLA is your plan name.

Thank you for the reply. But my requirement is to trigger a bamboo plan upon the completion of an external task which cannot be run via a bamboo task. As you have mentioned I already explored the option to use a rest call to trigger a plan programmatically; however I do not want to maintain certain configurations in the external task , hence the requirement is to trigger a bamboo task via a custom rest service plugin. The sample code provided to trigger a build programmatically does not work in Bamboo version 5.11 and I was not able to configure the relevant code segment.

The code for Bamboo version 5.11 is,

public TestService( BuildExecutionManager buildExecutionManager, PlanExecutionManager planExecutionManager, PlanManager planManager,
 VariableDefinitionManager variableDefinitionManager, CredentialsAccessor credentialsAccessor){
 this.buildExecutionManager = buildExecutionManager;
 this.planManager = planManager;
 this.planExecutionManager = planExecutionManager;
 this.variableDefinitionManager = variableDefinitionManager;
 this.credentialsAccessor = credentialsAccessor;
 
 }
 public void setBranchIntegrationService(final BranchIntegrationService branchIntegrationService){
 this.branchIntegrationService = branchIntegrationService;
 }
 public void runPlan(){

BuildContext buildContext = null;
 Plan plan = planManager.getPlanByKey("ADT-RRR");
 BuildContextBuilderFactoryImpl buildContextBuilderFactory = new BuildContextBuilderFactoryImpl(branchIntegrationService, variableDefinitionManager, credentialsAccessor);
 BuildContextBuilder buildContextBuilder = buildContextBuilderFactory.createBuilder();
 buildContextBuilder = buildContextBuilder.buildDefinition(plan.getBuildDefinition());
 buildContext = buildContextBuilder.build();
 buildExecutionManager.execute(buildContext);
 }

The following error triggers upon the execution of the above code.
