The current stack is Maven with modules per domain.

The main module imports the others.
And have a basic spring application on src and a testNG/cucumber/springboot runner on test.

I run that test runner from Surefire and works. Even with threads.
From IDE the same.

How can I create a uber jar with dependencies from that test runner so I can run cucumber features from self sustainable jar?

Tried assembly, jar and shade plug in with several different errors.
