Trying to build a jar of my project with external (and probably badly added) libraries on intellij

Question

I'm trying to build a .jar of my project in order to be able to start it without using IDE/shell, and maybe permit usage on different machines and OS.

I'm using intellij, and the .jar i produced up until now gives me the following error:

I imagine the problem is how I included the libraries in my project. I'm using javafx and jfreechart, and since I'm not an expert on library usage, i googled a lot to be able to use them, and I stopped as soon as sample code started working, and in the end:

• I downloaded javafx on my computer, included it by using File > Project Structure > Libraries and using the local address

• I included jfreechart building the project with maven

I'm not used to working with libraries, so I apologize for my complete ignorance and if I'm not using the correct terminology.

I don't know what I should do: try and include the libraries properly? How? Add some magic line of code to the mop that's gonna solve my problems?
