JavaFX:更新到 Java 9 后出现奇怪的 ClassNotFoundException [英] JavaFX: Weird ClassNotFoundException after updating to Java 9

问题描述

我在 Java 8 中启动了一个 Maven 项目，并想将其迁移到 Java 9.同时我也从 Eclipse Neon EE 转到了 Eclipse Oxygen EE.(重新安装了 JFX SDK).虽然 Eclipse 工作区没有显示任何错误；一旦我尝试编译和运行过去在 Java 8 中完美运行的完全相同的程序，我就会得到以下异常:

I started a Maven project in Java 8 and wanted to migrate it to Java 9. At the same time I also went from Eclipse Neon EE to Eclipse Oxygen EE. (JFX SDK reinstalled). While the Eclipse Workspace shows no errors; as soon as I try to compile and run the exact same program that used to run perfectly fine in Java 8, I get the following Exception:

{...}
Caused by: java.lang.ClassNotFoundException: com.sun.javafx.css.converters.PaintConverter
at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:582)
at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:185)
at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:496)
... 26 more

运行应用程序application.Main的异常

Exception running application application.Main

我现在已经多次重建该项目，但无法使其正常工作...

I have now rebuilt the project several times and cannot get it to work...

推荐答案

在Java 9中，之前的内部类

com.sun.javafx.css.converters.PaintConverter

公开身份

javafx.css.converter.PaintConverter 在 javafx.graphics 模块中.

javafx.css.converter.PaintConverter in the module javafx.graphics.

参见 Javadoc - 类PaintConverter.

JFoenix 支持带有 单独的 JAR.
