Re: [mylyn-integrators] Mylyn API usage from a headless application 
Hello Steffen,

thank you for the detailed comments and the bug references!
So if I understand correctly there is currently no official way to use this kind of API e.g. on an RCP target basis for Mylyn (3.8.3) that came with Juno? 

With best regards,
MarkusT

Hi,
that's great to hear that you are reusing Mylyn in this way. We have indeed started working on improving the core/ui split to support use cases of this sort better. I would recommend taking a look at these two bugs:
386117: [api] tasks.core relevant extensions should not be declared in tasks.ui, https://bugs.eclipse.org/bugs/show_bug.cgi?id=386117 316253: [api] provide access to instance of IRepositoryManager through core API, https://bugs.eclipse.org/bugs/show_bug.cgi?id=316253
The first one is about moving the connector extension point into the tasks.core bundle to enable discovery of connectors in headless contexts. The tasks framework would still require the extension registry so this would work best in OSGi environments but connectors could be used through the framework without the UI more easily.
The second change is about moving life-cycle management of repositories and the task list into a core bundle and exposing the data model as an OSGi service. This would allow headless clients to work with the default task list and repository instances which are currently only accessible from the UI. Another goal of the change is to extract the code for creating the model instance. This would allow clients to instantiate their own tasks model with separate connector instances, caches etc. more easily. Those model instance wouldn't interact with the Mylyn UI but still support all core functionality such as query synchronization.
It'd be great if you could comment on the bugs and let us know what your requirements are and help evaluate the proposed changes. Also, please feel encouraged to file new bugs if you have other requirements that aren't already captured in Bugzilla.

    Hello,

    we, the Jubula team, are currently working on a better integration
    with various ALM tools using the Mylyn API.

    We aim for a connector and repository neutral solution to report
    test results (via auto-generated comments) to arbitrary tasks for
    any task repository that is supported by Mylyn. This is so far
    looking pretty good using the Mylyn Tasks / Core API from within a
    standalone RCP UI application.Therefore we're using the
    "TasksUiUtil" and "TasksUi" API to access the global repository
    manager.

    Since we would also like to report those information from our
    commandline tools (e.g. our headless tool for test execution
    "testexec") during a nightly CI run we are currently searching for
    a solution to gain access to e.g. all configured repositories for
    a given workspace from within a headless context (an RCP
    application without an active workbench; the platform itself is
    running).

    I've already found some information [1] discussing this topic but
    as we would like to implement a connector independent solution
    this is currently too specific for our needs.

    So my questions are:
     - Are there already any Mylyn services / platform mechanism
    present (which I've missed so far) to achieve this?
     - If not, are there any plans to move the code to retrieve the
    repository manager so that it would also be usable from a non-UI
    context?

    Thanks in advance for any comments and with best regards,
    MarkusT
