failed to open stream: Permission denied error on Jenkins job

Question

Disclaimer: Never used php in my life. New to Unix and Jenkins

I have set up Jenkins on my Ubantu system. PHPUnit - 3.6.5 and PHP 5.3.3

I have a build file which execute simple unit test. All goes well when I execute it from command like -

ant phpunit

But when I set up a job for same to be executed from Jenkins job, then I encounter exception -

phpunit:

I understand that this is permission issue when I am trying to execute php unit test from Jenkins (which works well from command like). I started Jenkins as sudo user

sudo /etc/init.d/jenkins start

but of no avail. Am I missing some thing obvious?

Answer 1

Jenkins, in default mode, switches to the jenkins user for all execution not matter how you start the demon.

Try a sudo chown -R jenkins . on the folders.

For a system wide install they would be under /var/lib/jenkins/jobs/yourjob/ but for your side it seems to be under /home/tarunb/Documents/Tarun/mydemo/.
