copied!<p>Downsides of ClearCase - an addition to the most in-depth post here.</p> <ol> <li><p>The merge tool is not worthwhile. It barely helps you, remembers no decisions you made, its just a glorified diff.</p></li> <li><p>The merge tool has to check out directories to even CHECK if they need a merge. Its a bit insane.</p></li> <li><p>I use BitKeeper at work (let's assume Git), and merging two repositories even if there are conflicts is so trivial and user friendly even with command line, while ClearCase having tons of GUI tools is a long and laborious process which is also extremely error prone.</p></li> <li><p>All GUI tools require a ton of latency. Even seeing what can be done on a file requires a high speed connection. So right-clicking in the ClearCase tool on a file working from home could take a minute or two having high speed internet because of the extreme amount of networking requirements.</p></li> <li><p>Someone can completely mess up the repository or check-ins if they make their view spec different than the team. Which is quite insane that nobody can just check out some branch; they need the appropriate view spec which will incidentally give them the right stuff. The whole concept can be nice and flexible but 99% of the time it just causes lots of pain. Did I mention you can't email your spec via Microsoft Outlook since CC tools don't accept UTF-8 so you can't copy-paste it?</p></li> <li><p>I have absolutely <strong>nothing</strong> nice to say about CC. I used it for 2 years at 2 companies and dropped it in a heartbeat feeling happy the entire time. It is also impossible to just experiment with at home with your own projects, so you will still learn SVN or Git at home, and be forced to go through ClearCase pains at work. Nobody I know has ever used CC voluntarily. They only use it because some manager at work decided CC is the path to salvation and forced everyone to migrate to it. In fact my last company migrated from CVS to ClearCase, and after one year from ClearCase to SVN. It was that hated.</p></li> <li><p>ClearCase is not just one thing that makes you say no. It's like living in a house infested with ants. Each ant is just a minor inconvenience at best, but the infestation will drive you mad.</p></li> </ol>
