ClearCase rebase

[kinook]

The ClearCase action incorrectly uses -baselines instead of -baseline for the Baselines field. That will be fixed, but for now you can work around the problem by using the Additional command-line options field on the Options tab instead.

As far as the specific syntax for what you're trying to do, if the links mentioned don't help, log a support ticket with IBM/Rational support for questions about cleartool syntax.
