Eclipse forcing you to have a\npre-created empty directory that it doesn't create itself if it doesn't\nexist sounds mightily weird though. I'd guess there's some setting in\neclipse that tells it to automagically create or wipe the directory if\nit needs to. It's not like it's a small project, so I can't imagine a\nsimple thing like that not being handled.\n\n-- \nAndreas Ericsson andreas.ericsson@op5.se\nOP5 AB www.op5.se\nTel: +46 8-230225 Fax: +46 8-230231\n\nConsidering the successes of the wars on alcohol, poverty, drugs and\nterror, I think we should give some serious thought to declaring war\non peace.\n"},{"id":"150843","messageId":"CDEB2042-A498-4950-A3CD-27F111455234@sb.org","threadId":"25118","inReplyTo":"4C91D631.9010108@op5.se","subject":"Re: empty directories and git Question","fromName":"Kevin Ballard","fromEmail":"kevin@sb.org","sentAt":"2010-09-16T19:30:15Z","receivedAt":"2010-09-16T19:30:15Z","isPatch":false,"sender":{"key":"kevin@sb.org","avatar":"https://avatars.githubusercontent.com/u/714?v=4"},"body":"Apologies to those who were CC'd on the original message, I'm resending to this list as I forgot to set plain text.\n\nI've always wondered about that.
