exit-status: -1 when kill process through jenkins - jenkins

Question

I have used Jenkins for build and deploy my artifacts to server. After deploying files I stopped service by using kill command
kill -9 'pgrep -f service name'
note that the service killed but jenkins job fail with status code -1 although this command works fine when I use it at shell of linux server without jenkins
Please help me why I get -1 exit status?
and how I can kill process at linux server through jenkins job without failure ?
Edit : the below logs which appears after adding /bin/bash -x to my script:
#/bin/bash -x
pid=$(pgrep -f service-name); echo "killing $pid"; kill -9 $pid;

If you want to kill any process whose full command line match service-name you should change your script:
#/bin/bash
pgrep -f service-name | while read pid; do
ps -ef | grep $pid # so you can see what you are going to kill
kill -9 $pid
done
Command pgrep returns a list of process one per line.
In order to get pid list separated by a space and call kill command once:
#/bin/bash
kill -9 $(pgrep -f service-name -d " ")
In order to view which process are selected by pgrep use:
pgrep -a -f sevice-name
or
ps -ef | grep service-name
use man pgrep to see all options
In your case, job is killed because pgrep match the job script, so you should use a more specific pattern with the -x parameters:
#/bin/bash
pgrep -xf "java -jar /root/service-name --spring.config.location=/root/service-name/application.properties" | while read pid; do
kill -9 $pid
done
