One of the cool new features in EPF Composer 1.2 (as well as RMC 7.2) is that they support shell sharing with Eclipse 3.3. So, if you already have Eclipse 3.3 on your machine you can install EPF Composer just right into it. Just copy-paste everything from EPFC’s features and plugins directories into the respective directories of Eclipse 3.3 and start it. (It will prompt you to override files, but if you use the Eclipse and EPF release versions it will just override the same files. If you do this with updated versions of Eclipse, check which files you are overriding one by one).You can now take advantage of useful Eclipse plugins for EPF Composer. For example, you can use Mylyn to directly and graphically search, modify, and create bugzillas on bugs.eclipse.org. See this screen shot for an example.
All you need to do is to open the Mylyn views inside your authoring view. The “Task Repositories” view already has bugs.eclipse.org pre-configured. All you have to do is to add is you username and password (double-click). The Task List shows bugs that yo manually added here. Click on the little arrow symbol on the right and “Search Repository..” to run a query. You add the bugs to your list via a right-click on the search results. Very handy extension.
