Importing a module outside of Jenkins home directory

I am trying to run a custom Python module located at '/home/modules/module.py'

The python script is run by Jenkins and located at '/home/user_name/scripts/script.py'

Since Jenkins home directory is '/var/lib/jenkins' how can I import my module?

I have tried adding the following to the python script:

import sys
sys.path.insert(0,'/home/modules') """also /home/modules/"""

import module

but I am still getting the error:

ImportError: No module named

I am running everything in Ubuntu 14.04 and Python 2.7

EDIT:

I changed Jenkins user directory like this:

root@dwh-01:~$ usermod -m -d /home/jenkins jenkins

and modified JENKINS_HOME=/home/jenkins in /etc/default/jenkins

I think I can work with this, but now the issue is, if I log into jenkins shell and do:

jenkins@dwh-01:/$ cd
bash: cd: jenkins/: No such file or directory

Should the behaviour of the cd command direct me to /home/jenkins/ ? If I repeat the same when in /home/ It works though.

If I try and start jenkins, it gives me:

EDIT-2:

User jenkins home dir error fixed, I just made sure the home directory of the user was /home/jenkins using usermod -d /home/jenkins jenkins

I'm a step closer to importing the module, but am still having issues going one step outside of the jenkins home directory.

You should have two options that would allow you to import module into your code.

Option 1

import sys
sys.path.append('/home/modules')
import module

Option 2

import importlib.machinery
importlib.machinery.SourceFileLoader('module', '/home/modules').load_module()

If neither of these work, hopefully they will at least point you and others in the right direction.

Ok finally figured it out. What I did was change in the /etc/default/jenkins file the variable JENKINS_USER and JENKINS_GROUP to the user i needed to outside of the jenkins user folder (outside of /var/lib/jenkins).

This way the scripts ran by Jenkins will be ran as if it was the selected user I specified.

After that, I realized that in Jenkins, even if the working directory is /var/lib/jenkins/jobs/adjust_data_parser/workspace, scripts and files can be called from '/'

So the trick was:

-Accessing the script outside of the jenkins home directory

-Importing the module from its absolute path.
