java.lang.NoClassDefFoundError:com/sun/javafx/css/converters/SizeConverter [英] java.lang.NoClassDefFoundError: com/sun/javafx/css/converters/SizeConverter
问题描述
我正在SceneBuilder中创建JavaFX应用.
I'm creating a JavaFX app in scenebuilder.
我的FXML包含自定义胶子JavaFX对象.
My FXML contains custom gluon JavaFX objects.
我正在使用他们的"AppBar"和"Icon"对象.
I'm using their 'AppBar' and 'Icon' objects.
在加载fxml文件时，出现"java.lang.NoClassDefFoundError:com/sun/javafx/css/converters/SizeConverter"错误.
When loading in the fxml file, I get a 'java.lang.NoClassDefFoundError: com/sun/javafx/css/converters/SizeConverter' error.

我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.
I have checked past questions of a similar type, however the only solution they recommend is downgrading to Java8 - this is a Java13 project.
引用接受的回复:
在Java 9中，以前的内部类
In Java 9, the previous internal class
com.sun.javafx.css.converters.PaintConverter公开为
com.sun.javafx.css.converters.PaintConverter became public as
javafx.graphics模块中的javafx.css.converter.PaintConverter.
javafx.css.converter.PaintConverter in the module javafx.graphics.
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);
}
}
"getLoader"在其中检索具有正确目录的FXML加载器.
Where 'getLoader' retrieves an FXML loader with the correct directory.
我的gradle.build文件如下:
My gradle.build file is as follows:
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?
推荐答案
鉴于JavaFX在8至9+之间的主要API更改(其中，外观和CSS解析器已公开)，任何在JavaFX 13上运行的项目不能使用为Java 8创建的依赖项.
Given the major API changes in JavaFX between 8 and 9+ (among others, the skins and css parsers were made public), any project that runs on JavaFX 13 can't use dependencies created for Java 8.
2018年发布的Gluon Mobile 5( com.gluonhq:charm:5.0.0 )可与Java 8配合使用，这说明了您遇到的异常.
Gluon Mobile 5 (com.gluonhq:charm:5.0.0), released in 2018, works with Java 8, and that explains the exception you get.
有一个针对Java 9编译的Gluon Mobile依赖项:
There is a Gluon Mobile dependency that was compiled for Java 9: 5.0.0-jdk9.
虽然可能会解决您的问题，但该版本不再更新.
While that will probably solve your issues, that version is not updated anymore.
最新版本是6.0.2，并且该版本是为JavaFX 11+创建的.
The latest release is 6.0.2, and this version was created for JavaFX 11+.
此版本也可用于GraalVM，并且使用客户端插件，可以创建所有平台(桌面/移动/嵌入式)的本地图像.
This version also works with GraalVM and, using the Client plugin, allows creating native images for all platforms (desktop/mobile/embedded).
您可以在此处看到一个有效的示例: HelloGluon .
You can see a working sample here: HelloGluon.
该示例在台式机上运行良好，但是Gluon Mobile库旨在在移动版(iOS/Android)上运行，并且具有商业许可证.
The sample runs fine on desktop, but the Gluon Mobile library is intended to work on mobile (iOS/Android), and it has a commercial license.
