從ubuntu中拷貝eclipse的workspace到mac遇到的問題

進行submit操作時，提示：org.tigris.subversion.javahl.ClientException: Operation not permitted
進行更新操作時，提示：Attempted to lock an already-locked dir
進行刪除操作時，提示：Resource is out of sync with the file system

網上給解決方法是進行clean操作，不過在執行時也提示Operation not permitted，這個方法不行。
找到如下的參考網頁：

f you're changing workspaces on OS X and you import an SVN-based project into your new workspace, some of your files may have the uchg flag set. SubClipse/SVN will not be able to update this project. You will get an error:

svn: Cannot rename file

every time you try invoke svn. If you issue:

chflags -R nouchg .

at the top-level of the project directory this will clear these flags and restore SVN function.

於是在workspace目錄下執行chflags -R nouchg .
然後就可以順利執行clean操作了（右鍵項目 -> Team -> clean）。
可是在執行刪除操作時仍然提示：Resource is out of sync with the file system
參考如下網址進行解決：

Thought I'd put this here because when I went looking earlier I didn't
find a solution on Usenet. This error occurs when you edit a workbench
resource outside of Ecliple. To fix this problem, right click the
project or edited resource and select "Refresh". If you edit outside of
Eclipse a lot, you can enable auto-refresh by going to
Window->Preferences menu, then in the Preferences dialog box, select
General->Workspace. Check the "Refresh automatically" box.

This is for Eclipse 3.1. Don't know about other versions.

進行項目的更新，問題徹底解決。
