JETBRAINS - COMPILE PROJECT WITHOUT A MAIN CLASS

Hi,

This is my first post or question.

I would like to integrate Jenkins with my project that I have created in Jetbrains.

I am trying to package my Project into a JAR and I am following https://www.jetbrains.com/help/idea/compiling-applications.html#package_into_jar 

My main class, does not have accept any arguments because I have designed it this way but this is the base class when the program initiates.

When creating the artifact do I need to specify a main class entry point?

Thanks in advance!
