without following symlinks

[Dave Glowacki <dg...@ssec.wisc.edu>]

I've got a build file which runs a Unix program to set up a build 
directory.  Among other tasks, this Unix program creates symbolic links 
to several directories of utility programs.

One of the first commands the build.xml file contains is <delete 
dir="${builddir}">, which attempts to follow the symlinks and delete 
everything in the symlinked directories, which is NOT what I want to 
have happen.

Is there an option for the <delete> task telling it not to follow 
symlinks?

Thanks for the suggestions.  So far, I'm up to this:

   <delete includeEmptyDirs="yes">
    <fileset dir="workdir" followsymlinks="no" defaultexcludes="no"/>
   </delete>

which doesn't follow symlinks but also doesn't delete the symlinks 
themselves.

Any ideas?  (I'm using ant 1.6.0, but I didn't see anything related to 
this in the 1.6.1 release notes)

you could use a nested <fileset> with a followsymlinks="false" attribute.

see the manual page on FileSet.

There was a reponse to this e-mail that I deleted by accident.
One can use embedded filesets with followsymlinks, however
this does not work for all cases. I think that the "followsymlinks"
should be in the delete task as well. In this case, any directories
returned by the embedded filesets, or the directories returned from
the recursive deletion of the dir attribute will be tested for symbolic
linkness.

In the meantime, <delete dir="build"/> is extremely dangeous to
use if you are inclined to use symbolic links in the build directory.
(I was bitten by this :-[ ).
