I have recently put one of our projects on Hudson using the UCM ClearCase plugin. Hudson works well until a configuration changes and then it hangs at update. In ClearCase the user is prompted and asked if they would like to continue (yes/no) when theres a change so im guessing this is where Hudson is hanging.
I have configured Hudson to work with a snapshot view for speed so I would ideally like to avoid switching to a dynamic view.
The project uses ant for the build process.
