1. Error msg: SVN: a versioned directory of the same name already exists
Reason: I may have seen this problem before when somebody had committed the .svn directory itself to the repository. Thus, when trying to create the working directory, the versioned .svn directory couldn't be created because the working directory already had its own .svn directory.
解決辦法: 當前文件件搜索, 把所有.svn的隱藏文件夾都刪除, 在重新update其他人更新的.svn文件, 就沒有問題了.
