StyleConverterImpl class not found after trying executing generated jar file

Question

Hey guys so I have a generated jar file:

And the project uses two external jar files (fillo and jphoenix):

After I tried double click on the jar file nothing happens (it just shows the loading circle and thats it), I decided to run the jar file using cmd:

PS C:\Users\maljursa\Desktop\JavaFXApplication2\dist> java -jar "BFFT_One4All.jar"

And the error I got is:

Exception running application Main.Main

Appearently the class com.sun.javafx.css.StyleConverterImpl can't be found, but as far I can remember I don't remember using this import.

If you use Java 10: Try downgrading it to Java 8 or 9 as currently JPhoenix is not available for Java 10.
