However the issue tracker Trac 0.10 that comes with Buildix 2.1 does not support the advanced ticket work flows. So I decided to upgrade it to 0.11. The upgrade went very well. Meantime, I upgraded our eclipse environment to 3.4 as the IDE of our choice. The Mylyn task based UI plugin of eclipse works so great and the eclipse 3.4 version of Mylyn comes with JIRA, BugZilla and Trac connectors. However, by default Mylyn only supports Trac 0.9.2 Trac 0.10.x versions.
So basically we lost connectivity from Eclipse to our issue tracker with the upgrade. Then this article about Trac 0.11 and Mylyn becomes handy that provide simple instructions to make Eclipse 3.4 Mylyn talk to Trac 0.11.
I had to install TracXMLRPC 1.0.0 plugin from the Trac SVN repository and enable the plugin via Trac web admin module. I then re-started the apache web server as per the instructions given at the article I mentioned above The eclipse 3.4 Mylyn can now talk to Trac 0.11 issue tracker and I can see all the tickets.
Hope this blog helps other users who encountered issues in integrating Eclipse 3.4, Mylyn and Trac 0.11.
