Question

我有一个由java half和ruby half组成的程序。当我将java half编译成jar时，一切正常。当我只有原始.class文件时，ruby可以引用SimpleStringProperty，但是当我引用引用SimpleStringProperty的java类时，java给出：

LoadError: load error: designer -- java.lang.NoClassDefFoundError: javafx/beans/property/SimpleStringProperty

我已经能够将它减少到三个文件：一个引用javafx的java文件，一个不引用javafx的java文件，以及一个包含以下内容的ruby文件：

require 'jrubyfx' # requires ruby javafx bindings
require 'my.jar' # I ommit this line when using the raw .class files
p Java::javafx.beans.property.SimpleStringProperty
p Java::mypackage.NoJavaFX
p Java::mypackage.RefJavaFX

在我的cwd中使用jar运行时，我将其作为jruby -I . main.rb运行并输出：

Java::JavafxBeansProperty::SimpleStringProperty
Java::Mypackage::NoJavaFX
Java::Mypackage::RefJavaFX

然而，当我使用$ CWD / mypackage /中的.class文件作为jruby -I . main.rb运行它并输出：

Java::JavafxBeansProperty::SimpleStringProperty
Java::Mypackage::NoJavaFX

这让我相信有两个宇宙

我迷失了如何解决这个问题。非常感谢。
