Subject: Re: Detecting directory versus symlink


It is intended that <symlink action=3D"delete" ...> should silently ignore =
real files.  I would recommend testing this in existing releases before you=
 rely on it, but if you're a bleeding-edge type the code has been reworked =
quite a bit in Ant's trunk so should cure any problems you might encounter =
with the released code (not saying you will, but check!).  If you then try =
to delete the symlink and the directory is still available, it must be a re=
al one.  Failing that, you could drop down to scripting or custom task leve=
l where FileUtils has a method to check whether a file is a link (SymbolicL=
inkUtils in trunk)--the basic check is whether a file's absolute path and i=
ts canonical path are equal.  <symlink>'s documentation includes a caveat a=
bout using this check on non-*nix systems, but hopefully that is a moot poi=
nt for you.

Hope this helps,
Matt
