有时候CVS会报如下的错误

引用

Problems reported while synchronizing CVS Workspace. 0 of 1 resources were synchronized.
An error occurred synchronizing /XXXXX: The server reported an error while performing the "cvs update" command.
The server reported an error while performing the "cvs update" command.
XXXXX: The server did not provide any additional information.

原因也是不很清楚

解决办法是删掉文件，新建文件，然后Override and update就好了
