after 5 time try, the same module - collabnet in netbeans repository- could not be checked out, the same error took place, I was infored: the file already exists! I'm not sure this is the defect of the new CVS module or some other problem of you source repository now. see my screenshot attached -pprun
Created attachment 25424 [details] the error info dialog
Created attachment 25425 [details] the CVS check out ouput
the same problem with the debugger module in netbeans repository. And I forgot to emphasize that fiiles or directories doesn't exist in the place(say, the directory) the module will be checked out. Because I really have deleted it before retry (try to checkout again).
The dialog is now gone and update proceeds normally, see Issue #65517, it was fixed recently. As for your "FOO, foo" example, this repository cannot be checked out on Windows because its filesystem is not case-sensitive. We can do nothing about this.. However, due to fixing Issue #65517 update should now finish normally and only report those files that are in conflict.
Currently, I could not do a massive checkout, say, try to checkout all modules of Netbeans repository(maybe 10+ module, encounter it last night) I currently could not remember clearly what is the error info, just as one dialog appeared "pipe..." then I must to delete the broken module directory and figure out which one got checkout which one is not, finally, continue. It's really annoying.
