java.lang.NoClassDefFoundError: com/sun/javafx/css/converters/SizeConverter
我正在 scenebuilder 中创建一个 JavaFX 应用程序。
我的 FXML 包含自定义 gluon JavaFX 对象。
我正在使用他们的 'AppBar' 和 'Icon' 对象。
加载 fxml 文件时，出现 'java.lang.NoClassDefFoundError: com/sun/javafx/css/converters/SizeConverter' 错误。

我检查过类似类型的问题，但是他们推荐的唯一解决方案是降级到 Java8 - 这是一个 Java13 项目。
引用已接受的回复：
In Java 9, the previous internal class
com.sun.javafx.css.converters.PaintConverter became public as
javafx.css.converter.PaintConverter in the module javafx.graphics.
从这个方法调用加载：
private void profileClick( ActionEvent event) {
clearScreen();
Profile prof = new Profile();
ProfileController profController = new ProfileController(prof);
try{
mainPane.setCenter(profController.getLoader().load());
}
catch(Exception e){
System.out.println(e);
}
}
其中 'getLoader' 检索具有正确目录的 FXML 加载程序。
我的gradle.build文件如下：
plugins {
id 'java'
id 'application'
id 'org.openjfx.javafxplugin' version '0.0.8'
}
dependencies {
testCompile 'junit:junit:4.12'
testCompile 'org.testfx:testfx-junit:4.0.15-alpha'
testCompile 'org.hamcrest:hamcrest-all:1.3'
compile "com.opencsv:opencsv:4.0"
compile 'com.gluonhq:charm:5.0.0'
}
repositories {

maven {

}
mavenCentral()
}
javafx {

modules = [ 'javafx.controls', 'javafx.fxml' ]

mainClassName = "src.main.java.MainScreen"
我该如何解决这个错误？
考虑到 JavaFX 在 8 和 9+ 之间的主要 API 变化（其中包括皮肤和 css 解析器 public），任何项目在 JavaFX 13 上运行的无法使用为 Java 8.
创建的依赖项
Gluon Mobile 5 (com.gluonhq:charm:5.0.0)，于 2018 年发布，可与 Java 8 一起使用，这解释了您遇到的异常。
存在为 Java 9 编译的 Gluon Mobile 依赖项：5.0.0-jdk9。
虽然这可能会解决您的问题，但该版本不再更新。
最新版本是 6.0.2，此版本是为 JavaFX 11+ 创建的。
此版本也适用于 GraalVM，并且使用 Client plugin，允许为所有平台 (desktop/mobile/embedded) 创建原生图像。
您可以在此处查看工作示例：HelloGluon。
示例在桌面上运行良好，但 Gluon Mobile 库适用于移动设备 (iOS/Android)，并且它具有商业许可证。
