expect utility is not working when executing from jenkins

Question

we have a unix script which uses expect utility for interactive execution. This script works well when we run from unix server.

If we run this script from Jenkins, it is not working.

Below is the script

var="xxxxx"
expect -c "
    spawn sudo cp /abcd/sjws/config/obj.conf /abcd/sjws/config/obj.conf_jenkins
    expect {
    "Password:" { send $var\r;interact }
    }
    exit
    "

Below is the output when we run from jenkins

spawn sudo cp /abcd/sjws/config/obj.conf /abcd/sjws/config/obj.conf_jenkins 
Password: 
Password:
Build step 'Execute shell' marked build as failure 
Finished: FAILURE

Answer 1

Since Jenkins doesn't run it from an actual terminal, interact doesn't work, since there can't actually be any user interaction there.

You can replace interact with

expect eof
wait

Answer 2

Please use var='xxxxx' instead of var="xxxxx". Hope this help.
