I was running Hudson 1.396 and using scm-sync-configuration without any problems.

I moved to Hudson 2.2.1 with a fresh install and configuration of Hudson. I have my jobs building correctly, but I cannot get scm-sync-configuration to work correctly. I even move the previous SVN folder into a tag and created an empty folder for it to populate, but I always get this error:

(Maybe you need to enter credential?)

----- End Copy and Paste —
Entering a credential doesn't work, even if I mark it as global override. I created a Hudson job (as requested in the troubleshooting) and it is able to checkout the folder without problems.

I also followed the instructions here:
http://blog.vinodsingh.com/2009/08/hudson-svn-authentication-cancelled.html
However, I'm on Windows, so I may have missed something I should have deleted (I deleted the folder under Application Data and it didn't come back).

At this point, I'm at a loss as to how to make it work.

Thanks for your help.
