One way is to redirect the output from your shell commands to files:
cd 2>/tmp/cd_err
This would execute the cd shell command and redirect the error result to the
file /tmp/cd_err. Be careful with this and make sure you check the file for
contents. The redirect will create the file even if there are no errors. It may
be easiest to create a shell script to do the work and have it do the error
result checking. Ant is not really a scripting language. It provides basically
rule based processing and does not have the primitives that are in shells like
bash, csh etc.
The cd should move you the the login default directory. The ssh should probably
put you in the same place. I suspect you are trying to cd to a different
location.
For processing what you are trying to do the following is an approach you may
want to consider:
cd 2>/tmp/cd_err
if [ -s /tmp/cd_err ]
then
echo "Error during cd command" > /tmp/error
exit 1
fi
This would execute the cd command and capture the error output. The if
statement tests that the file exists and is non 0 in size. If the file exists
and is non 0, the file /tmp/error is created and the script exits. If you want
to ftp the /tmp/error file back to the system you are calling from it would
occur before the exit. You can then test for the existence of the error file
where it would be returned and fail the build if it exists.

I am reading my Ant book and can't seem to get my scrip to write the overall

failing on the first task and I can't seem to get it to spitout a file
because nothing runs after it fails.
