If you try to add the subversion plugin Subclipse to Sybase’s Workspace version 1.6 or 1.7, you will receive the following error:
To work around this problem, you need to start Eclipse.exe directly, usually located in your %SYBASE%\Workspace\Eclipse directory. Go to Help -> Software Updates -> Find and Install -> Search for new features. Add the url (http://subclipse.tigris.org/update_1.0.x) and Name (subclipse). When you’re given the option to install, uncheck the “Show the latest version of a feature only”.
We need to use version 1.0.5 of subclipse because Sybase’s Workspace is running on top of the older Eclipse version 3.1 software. The newer subclipse requires Eclipse 3.2 or higher to work.
Uncheck “Subclipse 1.2.0” and check “Subclipse 1.0.5”.
Continue installing, ignore any warnings.
The other option, of course, is to install Eclipse 3.2x separately and point Workspace to it during the install of Workspace. That way we are able to use the current version of Eclipse. I have not tried this with the new Workspace 1.7 release yet. Sybase Workspace is hardcoded to work only with Eclipse 3.1.x releases. 🙁
This seems to only happen on Workspace 1.6 and 1.7 that was upgraded from 1.6. I’m investigating it some more.
UPDATE: Sybase is going to create a techdoc explaining this behavior. This is somewhat expected behavior because of the older 3.1x Eclipse version.
