Jenkins ImportError module not found - python-3.x

Question

I have a file structure like this:
Main/
|----unit_tests
| |---test_main.py
| |---__init__.py
|--main.py
|--__init__.py
|--requirements.txt
test_main.py:
import unittest.mock
from main import MainFunction
from nose.tools import assert_is_not_none, assert_is_none, assert_equal
class TestMainLogic(unittest.case):
~~~ code here ~~~~
When running my unit tests in test_main.py from Pycharm, all is well. However when I try to run it in a Jenkins setup, I get:
+ python3 unit_tests/test_main.py
Traceback (most recent call last):
File "unit_tests/test_main.py", line 4, in <module>
from main import MainFunction
ModuleNotFoundError: No module named 'main'
Here's my Jenkinsfile:
pipeline
{
environment
{
PATH = "/home/jenkins/.local/bin:$PATH"
}
stages
{
stage('build')
{
steps
{
sh 'python3 --version'
sh 'wget https://bootstrap.pypa.io/get-pip.py'
sh 'python3 get-pip.py'
sh 'pip3 install -r requirements.txt'
echo 'build phase has finished'
}
}
stage('Lint')
{
steps
{
sh 'pylint unit_tests/test_main.py'
}
}
stage('test')
{
steps
{
sh 'python3 unit_tests/test_main.py'
}
post
{
always
{
cleanWs()
}
}
}
}
}
I've followed several posts and I'm just not getting an answer that works. I tried:Python module import failure in Jenkins and its linked answers. I do not have access to ssh into the Jenkins server and find the path so I need a way to set it at execution.

Answer 1

you need to use absolute import instead of relative in your test_main.py file.
in test_main.py
replace:
from main import MainFunction
# SOME CODE
with:
from Main.main import MainFunction
# SOME CODE
