Connect to your Bugzilla bug repository with the Mylyn Tasks Connector: Bugzilla plugin.
This can easily be installed by installing new software in Eclipse, selecting your most recent release in the “Work with:” selection box, type “mylyn tasks” in the filter text box, and then select the “Mylyn Tasks Connector: Bugzilla” plugin. Click next through the installation dialogs.
Once installed, you can access the view by selecting Window > Show View > Task List. If it is not displayed, click Window > Show View > Other … and select Mylyn > Task List in the popup window.
To add your repository, from the “Task List” view, click the “View Menu” icon ( a small downward arrow) and click “Show Task Repositories View”. From this view, right click on the white-space and click “Add Task Repository…” from the popup menu.
