Installing Eclipse Ganymede on this Linux machine was a breeze. Everything just worked out of the box. Well, not everything. SVN integration was missing. Installing Subclipse did not work nor did Subversive, at least not until I stumbled upon Basilikk's blog entry on Eclipse 3.4 Ganymede and Subclipse 1.4.
The critical paragraph was:
The second alternative is to also install the SVNKit adapter. This immediately causes Subclipse to work, there is no need to uninstall the JavaHL adapter. Downside of this of course is that you are using a beta version of the adapter. Hopefully there will be a final version of this adapter and an update to Subclipse 1.4.x to include a stable SVNKit soon.
In short, selecting the "SVNKit Adapter" during the usual installation of Subclipse worked as a charm.
