[mylyn-integrators] Using public Mylyn API to automatically create task

["Alexander Gurov" <alexander.gurov@xxxxxxxxxxxx>]

Hello All,

I tried to replace bug and tip reporting system currently used in the Subversive with the Mylyn-based one. Unfortunately it looks like not all required API parts are implemented by the Bugzilla connector. So, it looks like I cannot use public API parts and should use Bugzilla connector implementation details. But may anyone known how to use public API's in more successful way?

Currently I use the code which looks like:

  TaskRepositoryManager manager = TasksUiPlugin.getRepositoryManager();
  final TaskRepository repository = manager.getRepository(SendProductBugOrTip.ECLIPSE_BUGZILLA_URL);
  if (repository == null) {
   return;
  }
  AbstractRepositoryConnector connector = manager.getRepositoryConnector(repository.getConnectorKind());
  final AbstractTaskDataHandler taskDataHandler = connector.getTaskDataHandler();
  if (taskDataHandler == null) {
   return;
  }
  String kind = this.repository.getConnectorKind();
  AbstractAttributeFactory attributeFactory = taskDataHandler.getAttributeFactory(repository.getUrl(), kind, AbstractTask.DEFAULT_TASK_KIND);
  final RepositoryTaskData taskData = new RepositoryTaskData(attributeFactory, kind, repository.getUrl(), TasksUiPlugin.getDefault().getNextNewRepositoryTaskId());
  taskData.setNew(true);

  IActionOperation op = UIMonitorUtility.doTaskScheduledDefault(new AbstractActionOperation("Initialize Report") {
   protected void runImpl(IProgressMonitor monitor) throws Exception {
    if (!taskDataHandler.initializeTaskData(repository, taskData, monitor)) {
//    if (!taskDataHandler.initializeSubTaskData(repository, taskData, taskData, monitor)) {
     throw new CoreException(new RepositoryStatus(IStatus.ERROR, TasksUiPlugin.ID_PLUGIN,
       RepositoryStatus.ERROR_REPOSITORY,
       "The selected repository does not support creating new tasks."));
    }
   }
  }).getOperation();
  

  if (op.getExecutionState() == IActionOperation.OK) {
   taskData.setSummary("autogenerated summary");
   taskData.setDescription("autogenerated description (stack trace etc.)");
   taskData.setAttributeValue(RepositoryTaskAttribute.PRODUCT, "Subversive");
   taskData.setAttributeValue("severity", "normal");
   
   // open task editor
   NewTaskEditorInput editorInput = new NewTaskEditorInput(repository, taskData);
   IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
   TasksUiUtil.openEditor(editorInput, TaskEditor.ID_EDITOR, page);
  }

So, mainly the problem is that BugzillaTaskDataHandler.initializeTaskData() method have no implementation. There only two ways I found to initialize the task editor properly:

1) Initialize task data using AbstractTaskDataHandler.initializeSubTaskData(), but it also installs dependency to parent bug, which is undesirable moment

2) Use BugzillaRepositoryConnector.setupNewBugAttributes() method directly, but this class is a part of Bugzilla connector internal implementation.
