JFoenix JFXProgressBar fix

JFoenix_JFXProgressBar_fix.md

Problem: GUI thread Runtime Exception when using JFoenix JFXProgressBar.

Caused by: java.lang.IllegalAccessError: class com.jfoenix.skins.JFXProgressBarSkin (in unnamed module @0x5680343f) cannot access class com.sun.javafx.scene.NodeHelper (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.scene to unnamed module @0x5680343f

If you are using Gradle, then direct modify the run configuration (through the dialog) will NOT work.
Go to build.gradle,

plugins {
    id 'java'
    id 'application'
    id 'org.openjfx.javafxplugin' version '0.0.8'
}

group 'org.harutya'

    mavenCentral()
