Jenkins console output not in realtime

Question

When I run job (Build) on Jenkins I am triggering ruby command to execute my test script.

Problem is Jenkins is not displaying output in real time from console. Here is trigger log.

Building in workspace /var/lib/jenkins/workspace/foo_bar

No emails were triggered.

[foo_bar] $ /bin/sh -xe /tmp/hudson4042436272524123595.sh

+ ruby /var/lib/jenkins/test-script.rb

Answer 1

Make sure your script is flushing it stdout, stderr.

import sys

sys.stdout.flush()
