java.lang.NoClassDefFoundError: com/sun/javafx/css/converter



我正在场景构建器中创建一个JavaFX应用程序。

我的 FXML 包含自定义胶子 JavaFX 对象。

我正在使用他们的"应用栏"和"图标"对象。

在fxml文件中加载时,我收到"java.lang.NoClassDefFoundError: com/sun/javafx/css/converters/SizeConverter"错误。

完整跟踪:

我已经检查了过去类似类型的问题,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:

在 Java 9 中,以前的内部类

com.sun.javafx.css.converters.PaintConverter 公开为

javafx.css.converter.PaintConverter 在模块 javafx.graphics 中。

从此方法调用加载:

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加载器。

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 {
jcenter()
maven {
url 'http://nexus.gluonhq.com/nexus/content/repositories/releases/'
}
mavenCentral()
}
javafx {
version = "13"
modules = [ 'javafx.controls', 'javafx.fxml' ]
}
mainClassName = "src.main.java.MainScreen"

如何解决此错误?

鉴于 JavaFX 在 8 到 9+ 之间的主要 API 更改(其中包括皮肤和 css 解析器是公开的(,任何在 JavaFX 13 上运行的项目都不能使用为 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配合使用,这解释了您获得的异常。

有一个为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,并使用客户端插件,允许为所有平台(桌面/移动/嵌入式(创建本机映像。

你可以在这里看到一个工作示例:HelloGluon。

该示例在桌面上运行良好,但 Gluon Mobile 库旨在在移动设备 (iOS/Android( 上运行,并且它具有商业许可证。
