问题
I am creating a mini-JavaFX project and wanted to use the Awesome Font Icon Pack.I loaded the fontawesomefx-8.9 using the Scenebuilder and opened the FXML in it and loaded two icons in it, also added the JAR file in External Libraries in IntelliJ but when I run the code it gives a ClassNotFoundException for de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView. What should I do?
I removed the two Icons and the code runs fine. I searched many places but it only showed to add the JAR files to external libraries and nothing. I am using JDK 12 , JavaFX 12 and Scenebuilder 11.0.
FXML File
<?xml version="1.0" encoding="UTF-8"?>
<?import de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.RowConstraints?>
<fx:root alignment="center" hgap="10" type="GridPane" vgap="10" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Controller">
<children>
<Button mnemonicParsing="false" text="Click Me!!!">

回答1:
Since you are using Java and JavaFX 12, you should use a valid FontAwesomeFX version: 11.0.0.
You can find it here: https://bintray.com/jerady/maven/FontAwesomeFX/11.0.0
If you are using Maven or Gradle, you can just include the FontAwesome dependency:
dependencies {
implementation "de.jensd:fontawesomefx-fontawesome:4.7.0-11"
}
That will also include de.jensd:fontawesomefx-commons:11.0.
If you don't use Maven/Gradle, you will have to download them from here and here, and include them in your project.
Next step: since you have a modular application, your module descriptor should contain all the modules that your project requires.
Therefore your module-info should include the fontawesome module:
module Practice {
requires javafx.controls;
requires javafx.fxml;
requires de.jensd.fx.fontawesomefx.fontawesome;
opens sample to javafx.fxml;
exports sample;
}
Now your project will have all the required dependencies and will work.
