未找到 Windows WinPlatformFactory 上的 JavaFx + Felix

Question

我有一个使用 Apache felix 和 swing 的桌面应用程序，带有嵌入的 javafx UI，javafx 正在通过 maven 嵌入依赖项加载到项目中，它在 mac 上运行良好。

但是当我在 Windows 上运行它时，它给了我以下错误：

Answer 1

javafx 正在通过 maven 嵌入依赖项加载到项目中

我不认为嵌入 javafx jar 是正确的方法，如果这是你正在做的。我猜你会丢失一些原生部分。

宁可使用“org.osgi.framework.system.packages.extra”机制。

您可以看一下 Dromber FX 代码（JavaFX 的模块化应用程序框架，它结合了 JavaFX 和 OSGi；我是这个框架的作者）：

https://github.com/Drombler/drombler-fx/blob/release-0.9/drombler-fx-startup-main/src/main/resources/org/drombler/fx/startup/main/config.properties

Answer 2

如果 Windows JavaFX 版本（例如来自 Gluon）与 MacOS JavaFX 版本共享（破坏），也可能会出现错误 java.lang.ClassNotFoundException: com.sun.glass.ui.win.WinPlatformFactory not found。

看起来很安全，MacOS JAR 似乎在 jar 中缺少 WinPlatformFactory.class 组件，导致与 OP 相同的错误消息。

⁨javafx.graphics⁩.jar!com⁩/sun/glass⁩/⁨ui⁩/⁨win⁩/WinPlatformFactory.class

修复：

1. 不要对所有平台使用相同的目录
   --OR--
2. 用 Windows 版本破坏 MacOS 版本（警告： 最终可能会遭受相同和相反的命运，尽管测试似乎没有表明这一点）
