Re: [mylyn-integrators] Listen for changes when task data is updated 
Hi Steffen

Thank you for your answer. I want to develop an Eclipse plug-in (to monitor activity within the IDE). In the end, my plug-in should be able to count all tasks whose status changed during the day for a specific developer (at the moment I am only interested in any status change: e.g.: NEW: 12, RESOLVED/CLOSED: 1, EDITED/COMMENTED: 2, DELETED: 0).

I am now trying to describe the different ways I tried to solve my problem and I hope to clarify my wish and you may help me....:

Way 1:
I thought I'd  get all notifications and count it this way. I managed to add a ChangeListener to the tasklist and get notified from every change in the tasklist. In the changeListener (handler) I get a TaskContainerDelta-Set where I only was able to get the summary (text) and kind of the change, but unfortunately not the status. Can I get the tasks id and get some details (i.e. status) this way?

Way 2:
Another thought was to make a Mylyn query which shows me all tasks whose status changed within 1day (for a specified user).  I created a query which returned me the tasks I wanted (from the user and changed today). Now I tried to access the task (ITask). I could get the owner, ModificationDate, TaskId, etc. - but not what ahd changed and what the old and new state is. How can I get all these details from a ITask object?

If this is the right way to solve my problem, I also have two additional questions: This query obviously has to be made available within Mylyn and synchronized with the repository. I tried to add a new query to the taskList in the form of: taskList.addQuery(new RepositoryQuery("https://api-dev.bugzilla.mozilla.org/latest/bug?changed_after=1h&chfield=bug_status&include_fields=_default,history";, "test-query")); - but wasn't successful. I found no other way or examples in the documentation... Could you please give me a hint? At the moment I am testing my efforts with the mozilla-bugzilla-project I am "listening" to. Does the very same query also work, if I use for example Mantis as a bug tracker?

As already mentioned, I have difficulties in finding documentation or working examples. Therefore, I also tried to read code from existing projects to solve my needs. For example, I included the Mylyn-Mantis code and also tried to include the mantis-git-repository to my eclipse IDE (as described in the contributor reference, http://wiki.eclipse.org/Mylyn_Contributor_Reference#Checkout). Unfortunately, there are/were very few files (and almost no java) files... not the source code I searched for. What am I doing wrong?

I am aware of the fact, that this is a hard way for a student to do something like this (accessing data from own Eclipse plug-in from another plug-in via API). Luckily, I made a couple of (small) progresses towards my goal... When I first started this post, I was unable to access any Mylyn-Data. Now I am able to get changed tasks and some details ;) ... I really hope and I am really thankful if you could further help me!

Best regards,
	André

Hi,

the answer depends on how you are intending to integrate with Mylyn.

If you are developing a standalone application that uses Mylyn as a library to access Bugzilla or other repositories you would need to run queries to obtain the tasks you are interested in.

If you want to monitor activity within the IDE you would need to deploy your application as a bundle into the IDE and register with the running Mylyn instance through the classes Shawn mentioned on stack overflow.
