Ant Job Clone script
Ant target to clone a Template Hudson Job remotely
If you have a subversion repository that conforms to the suggestions laid down by the pragmatic programmers, then this ant target should allow you to trivially create Jobs on Hudson based on a template job and the current branch that your working copy is in.
I hope someone out there finds this useful. There are no dependencies on anything other than Ant and Subversion, but unfortunately due to the lack of a decent POST task there is a dependency on a Java+Ant combination that supports script tasks of type javascript (sorry).
This script could probably be improved especially around the regular expression replacements, a filter chain would probably be better.
