Project Plan For Mylyn, version 3.9


The mission of the Mylyn project is to provide:

  1. Frameworks and APIs for Eclipse-based task and Application Lifecycle Management (ALM)
  2. Exemplary tools for task-focused programming within the Eclipse IDE.
  3. Reference implementations for open source ALM tools used by the Eclipse community and for open ALM standards such as OSLC

The project is structured into sub-projects, each representing an ALM category and providing common APIs for specific ALM tools. The primary consumers of this project are ALM ISVs and other adopters of Eclipse ALM frameworks.

Please see the project charter for more details.

Ramp Down

After RC1 is released, builds will be produced weekly until the 3.9 release. In the RC phase only bugs marked P2 or higher or severity major or higher will be fixed. APIs will not change except to address critical fixes based on integrator feedback, until RC3, at which point APIs will be frozen.

Compatibility with Previous Releases

API Contract Compatibility: Mylyn 3.9 will be backward compatible with Mylyn 3.0.

Binary (plug-in) Compatibility: Mylyn 3.9 will be binary compatible with Mylyn 3.0.

Source Compatibility: Mylyn 3.9 will not by be source compatible with previous versions.

Workspace Compatibility: We intend to keep Mylyn 3.9 upwards workspace-compatible with all versions higher than Mylyn 2.0 unless noted. This means that workspaces created with Mylyn 2.0 can be successfully opened by Mylyn 3.9 and upgraded to a 3.7 workspace.

Themes and Priorities

In addition to using the planned themes listed below, we continue prioritizing the ongoing input of our growing user community.


Integration of continuous integration and build systems and seamless access to software build and assembly technologies. Mylyn users will be able to access continuous integration processes, control build execution and associate build results with tasks and context.

  • Proposed

    • support Hudson 3.0 [393141] (target milestone: 1.1)
    • support Hudson 3.0.1 (was: NPE when reading job) [404275] (target milestone: 1.1)


Framework of common UI, web service, REST and test utilities to be used by the rest of Mylyn and by other Eclipse-based tools.

  • Proposed

    • [api] support user defined categories in Team Repositories view [335790] (target milestone: 3.9)


Usage monitoring, degree-of-interested modeling and the task-focused user extensions implementation for the Eclipse UI, which re-aligns the user experience around tasks and provides features such as workspace focusing and one-click multitasking.

  • Deferred

    • Include breakpoints from the current context into the context data [155333] (target milestone: 3.10)


Eclipse-based access to documentation systems such as Wikis and other portals. This builds on the Mylyn WikiText framework.

  • Proposed

    • split context dependencies into separate bundle from o.e.m.wikitext.tasks.ui [404858] (target milestone: 1.8.0)
    • Support Markdown in WikiText [329528] (target milestone: 1.8.0)


Eclipse-based code review functionality that's seamlessly integrated with the Tasks and SCM systems supported by Mylyn. Eclipse integration for Agile code reviews, the formal IEEE code review process, review reports with BIRT and aim to support many Eclipse artifact for reviews, e.g. JDT (Java files), CDT (C/C++ files), EMF (models).

  • Proposed

    • Define a common model for reviews [324327] (target milestone: 2.0)
    • indicate whether each file is modified, deleted, or renamed [383359] (target milestone: 2.0)
    • [model] Implement EMF Edit support [400165] (target milestone: 2.0)
    • design generic remote API for retrieving review details [400167] (target milestone: 2.0)

    • support Gerrit 2.5 [393798] (target milestone: 2.0)


Integration with Agile, issue, bug and defect tracking servers. Mylyn Tasks provides rich task editing, task list management and offline synchronization for ALM servers. Central portion of the ALM integration framework used by other projects, eg, task-based changed tracking for the SCM project.

  • Proposed

    • support deleting of Trac repository tasks [404961] (target milestone: 3.9)
    • [api] provide scrollbar to task repository properties page [253142] (target milestone: 3.9)
    • add "Requirements" as new team category [378031] (target milestone: 3.9)
    • prompt users to disable "Show subtasks not Matching Query" [360055] (target milestone: 3.9)
