bash script ruing correctly in linux machine but not when executed via jenkins from a windows machine

I have a bash script as below: ------------------------------

#!/bin/bash

VAR_A=$(echo "cat //artifact/fileName" |  xmllint --shell BuildResult.xml | sed '/^/ >/d' | sed 's/<[^>]*.//g' | tr -d 'n' | awk -F"-------" '{print $3}')
echo $VAR_A
------------------------------

I have jenkins installed on a windows machine and via cygwin openssh, I am coecting to the suse linux machine in which this script is residing.

When I am calling the above script via an ANT sshexec command configured in Jenkins, it is ruing ok but no output.

On the other hand, when I am ruing the same script from within the SUSE Linux system, it is echoing current result.

I am not able to figure the root cause and respective fix. Checked the shell in suse linux and it is set to /bin/bash system wide.

Please help.

It is urgent.

Thanks. Nishant
