If you have installed Eclipse Ganymede and wanted to use SVN integration, you realised that you need to install additional SVN providers and connectors. This is described f.e. on blog post Getting SVN running under Eclipse 3.4 Ganymede.

Problem

However, when I followed those steps to get SVN running in Ganymede, I still could not see any commands like Team/Update for my existing projects in Eclipse.

Solution

You need to reconnect SVN integration by following these steps:

• Select all projects you want SVN integration to reconnect for
• Choose Team > Share projects
• Choose svn
• Choose option Use projects settings and finish wizard

From now on you will have all SVN commands for project available.
Cheers, hope this helps.
