I just tried to commit my Working Copy when I got the error message:
svn: Entry 'jquery-latest.js' has unexpectedly changed special status
It turns out that someone had created a symlink to whatever is the latest version of jQuery, which apart from being a somewhat dubious solution, should be fine. However, it seems a Windows user then checked out this file and somehow changed it; either directly or by some strange Windowsy magic. Anyway, the changed file was then corrupted and the result is the rather cryptic message above.
I tried to remove the offending file:
svn remove jquery-latest.js
But that resulted in:
svn: 'jquery-latest.js' is in the way of the resource actually under version control
Which was simpy resolved by using the
svn remove --force jquery-latest.js
I recreated the symlink, committed it and it seems now to be ok.
