Hi all -
I'm trying to use Ant to help automate a software install/update process: a
ZIP download and unpack, remove empty directories, create symlinks in their
place, and then apply some simple regex/replace tasks. I have the process
worked out on a FreeBSD machine, but as soon as I move the build.xml to a
Linux system, things fail when I try to create the symlinks.
I've been working with the assumption that I may be either updating an
existing install (ie I have symlinks) or I am installing fresh (ie I have
empty directories), so the tasks are... uh, probably unnecessarily verbose
(suggestions for improvements welcome). The error on linux comes in when
the `symlink` task is called: I get the following BUILD FAILED error:
'Deletion of file at /home/bridger/bin/basex/data failed, while trying to
overwrite it with a symlink.'
Any suggestions about what to do to fix this and make it more robust?
Thanks in advance for your time and help.
Best,
Bridger
