我刚刚使用我的capistrano部署了一个旧项目，它部署好了，但我需要回滚。当我尝试使用命令'cap deploy：rollback'回滚时，我收到此错误：
[Deprecation Warning] Naming tasks with before_ and after_ is deprecated, please see the new before() and after() methods. (Offending task name was before_update_code)

如果我启动'cap shell'并快速查看，我找不到它正在寻找的20121023112609目录。
cap> ls -x /home/<my user>/<my project>/releases

我可以看到我的最新部署在那里，但它被称为'20121023111648'，而我想要恢复的先前部署称为'20121023110110'。
好像有时差或什么？
