Mylyn/SOC/2006/Trac Connector

The goal of this Google Summer of Code project is to provide a Trac connector plug-in for Mylar. Trac is a web-based issue tracking system with an integrated wiki.

The Mylar API already supports multiple issue tracking systems, therefore the existing abstraction can be used to implement a Trac connector. Trac issues can be accessed remotely through an query script that outputs tab-delimited text as well as through an XML-RPC interface. The XML-RPC interface has not yet been integrated into the main distribution of Trac but is available as a separate plug-in.

The project has been accomplished in two iterations. The goal of the first iteration was to make the connector work with existing Trac deployments through Trac's web interface. This retrieved ticket information is used for read-only display in Mylar. Tickets can be edited through a web-browser.

The second iteration focused on enhancing the support for Trac's XML-RPC interface. The XML-RPC interface allows full featured access to all ticket information and allows manipulation of tickets. The editing of tickets is done through Eclipse forms based editor.

The Trac connector is now maintained in the Mylar CVS and is shipped with the regular releases.


M1 (completed): Web linking only repository integration (#148378)

  • Create and edit Trac repositories (#147817, #148378)
    • Templates for common repository locations (#150677)
  • Data model for repository access (#147816)
    • Access through Trac's query script (#148090)
    • Access through the Trac XML-RPC plug-in (#148089)
  • Create new tasks through web-browser (#150699)

  • Change query urls accordingly when repository url is changed (#154798)
  • Authoring of reports within native Eclipse editor (#151899, #146334, #154377 )

This milestone is available as part of the Mylar 0.6.2 release.

Future planning

Please refer to the Eclipse Bugzilla for bug reports and feature requests.


Please refer to the Mylar download page.


Please refer to the Mylar_Contributor_Reference for information about how to obtain and build Mylar and its connectors.

The source is available in the Mylar CVS:


Project Team Set:


  • Core and Model: Provides Java abstraction for repository access
    • Abstraction for query script and XML-RPC access
    • (Eclipse independent) model classes that represent Trac data
  • UI: Tasklist classes
  • Tests: Test for Core and UI

Since Core and Model is only used by UI both are combined in a single plug-in.

For the XML-RPC calls Apache XML-RPC is used.
