I'm scared of clearcase. Any other SCM system gets into a mess, you cant
check in or check out code. but with clearcase the code repository on your
local system just 'disappears' till you fix it. I had one epic to cross
mount pcs to recover one box.

Cron works, cruise control and anthill work more often. They are just
fiddlier to set up. Anthill is nice and simple, even if restricted to CVS.

yes

agreed.

that may work in a big project. our philosophy is 'everyone owns the build';
so there is no one build master.

Core is not having developers break builds; by giving everyone the ability
(ant) to make the master build, and the responsibility to not check in code
that wont compile or pass the basic unit tests, you should not have a build
that breaks with compilation errors, and with a fast build process any
check-in conflicts get caught within a few minutes.

Builds still break for other reasons, of course, but for functional errors,
rather than compile errors.
