Hudson version 2.1.2 has support for SVN 1.6 via Hudson Subversion Plug-in. But I wanted the magic of centralized metadata so upgraded to SVN 1.7. Hudson needs to be upgraded to 2.2.1 to take advantage of SVN 1.7 so as a workaround you can use the following build step:-
- Install SVN client 1.7 on the server : http://www.collab.net/downloads/subversion
- Go to Hudson build job->Configure
- Disable Source Code management via Subversion
- Add Build Step->Execute Windows batch command:-
Basically you are deleting code and checking out manually rather than Hudson plugin doing it.
