How to create a working executable jar file of a Java FX 8.0 Application

In my java fx application I used mysql as the database.I developed this application using InteliJ IDE, and for the User interface I used scene builder and also I used jfoenix,jasper and mysql libraries in this project.I created artifact and build an executable jar file correctly but I got an exception when I runs that jar file.
"C:\Program Files\Java\jdk1.8.0_161\bin\java.exe" -Dfile.encoding=windows-1252 -jar D:\onetcoNew\onetco_pos_system\out\artifacts\onetco_pos_system\onetco_pos_system.jar

JavaFX NullPointerExcepion # FXMLLoader.load(...) (URL is null)

The problem is .load() function at
Parent root = FXMLLoader.load(getClass().getClassLoader().getResource("/resources/PrimaryScene.fxml"));
Seems like it doesn't see the fxml file. I have done research on many similar questions here and there, but none of them helped. I tried multiple paths or moving fxml to main class etc.
Might be some problem with IDE configuration, i don't know what else can i do to make it work.
Im working with IntelliJ Idea Java 1.8(so JavaFX is automatically added). What may be important is the project was created as Empty Project not a JavaFX Project. I tried running another project as JavaFX project and it worked fine.
Im attaching error below:

Just make sure to put the fxml file into the src/main/resources/ directory of your project.
Also make sure that src/main/resources is marked as the resource root in intelij
Right click on folder -> Mark directory as -> "Resource Root"
Then use
Parent root = FXMLLoader.load(getClass().getResource("/PrimaryScene.fxml"));
Also duplicate of JavaFX and maven: NullPointerException: Location is required

Can't run program in command line while using LauncherImpl.launchApplication

I'm doing an application and I recently add a splashscreen with LauncherImpl.launchApplication (as a preloader for my app). Before that I was able to run the program in command line and in eclipse. Now eclipse works fine but no more command line. Here is my problem : Why can ide work but not cmd line ?
I get these errors :

Exception running application view.MainApp
Moreover eclipse says for LauncherImpl.launchApplication :
Discouraged access: The method 'LauncherImpl.launchApplication(Class, Class, String[])' is not API (restriction on required library 'C:\Program Files\Java\jdk1.8.0_161\jre\lib\ext\jfxrt.jar')
I have never seen such an error before, I found this on internet : Access restriction: The type 'Application' is not API (restriction on required library rt.jar)
But in this example I'm not sure they are using an executable jar. However I have to use one. And with an executable jar, even if I change rules as explained it doesn't work.
Help would be appreciate.
Thank you.

You should configure scene builder to use the jar your application uses.
Configure them with the Import JAR/FXML File ... menu.

Error when trying to run spring boot jar file

I am trying to run a spring boot jar file with java -jar on a windows system.
Below are the steps that i have followed
Created a simple Spring Boot project with Maven as build tool
Update pom.xml to use spring-boot-maven-plugin to bundle dependencies in jar file
Create a jar file using mvn clean install and try to run the jar.
It fails with the following exception:
