问题描述
我的程序之前运行良好，我将场景构建器从 JavaFx 场景构建器 2.0 更改为 gluon 场景构建器 10，以添加一些 CSS 样式.我添加了样式，程序显示错误，例如警告:使用 10.0.1 版的 JavaFX API 加载 FXML 文档，使用 9.0.4 版的 JavaFX 运行时然后我将我的 JDK 更新到 10.0.2 版，但是它 stii 显示这样的错误.
My program worked perfectly before, And I changed my scene builder to gluon scene builder 10 from JavaFx scene builder 2.0 to add some CSS styling. I added the styling and the program showed errors like WARNING: Loading FXML document with JavaFX API of version 10.0.1 by JavaFX runtime of version 9.0.4 And then I updated my JDK to version 10.0.2 but it stii shows errors like this.

堆栈跟踪将此显示为错误的行
The stacktrace show this like as the wrong line

我已经浪费了 3 个多小时来寻找答案.所以请帮我解决这个问题.
I've been wasting more than 3 hours for finding an answer. So please help me with this.
字体很棒的版本:
推荐答案
这个错误:
Caused by: java.lang.NoClassDefFoundError: com/sun/javafx/css/parser/CSSParser
at de.jensd.fx.glyphs.GlyphIcon.<clinit>(GlyphIcon.java:48)
at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
表示您的依赖项之一 (de.jensd.fx.glyphs.GlyphIcon) 正在尝试访问不存在的类 (com.sun.javafx.css.parser.CSSParser) 在您的 JDK 9/10 中.
indicates that one of your dependencies (de.jensd.fx.glyphs.GlyphIcon) is trying to access a non existing class (com.sun.javafx.css.parser.CSSParser) in your JDK 9/10.
在 Java 9 版本中，许多私有的 JavaFX 类 (com.sun.javafx.*) 被移至公共 API(在本例中为 javafx.css.parser.CSSParser).
With the Java 9 release, many JavaFX classes that were private (com.sun.javafx.*) were moved to public API (in this case, javafx.css.parser.CSSParser).
如果您在 Java 9 或 10 上运行，则必须使用至少与 Java 9 兼容的第三方依赖项.
If you run on Java 9 or 10, you have to use third party dependencies at least compatible with Java 9.
从您的依赖项列表中:
- 控件FX
8.40.11 兼容 Java/JavaFX 8.您需要使用 ControlsFX 9.0.0
8.40.11 is compatible with Java/JavaFX 8. You need to use ControlsFX 9.0.0
您可以下载jar 来自 Maven Central，或者添加 maven/gradle 坐标:
You can download the jar from Maven Central, or add the maven/gradle coordinates:
<dependency>
<groupId>org.controlsfx</groupId>
<artifactId>controlsfx</artifactId>
<version>9.0.0</version>
</dependency>
或:
compile 'org.controlsfx:controlsfx:9.0.0'
- FontAwesomeFX
FontAwesomeFX 8.15 也兼容Java/JavaFX 8，所以需要使用9个版本:
FontAwesomeFX 8.15 is also compatible with Java/JavaFX 8, so you need to use the 9 versions:
罐子:fontawesomefx-commons, fontawesomefx 控件
或依赖项:
compile 'de.jensd:fontawesomefx-commons:9.1.2'
compile 'de.jensd:fontawesomefx-controls:9.1.2'
其他:
compile 'de.jensd:fontawesomefx-emojione:3.1.1-9.1.2'
compile 'de.jensd:fontawesomefx-fontawesome:4.7.0-9.1.2'
compile 'de.jensd:fontawesomefx-icons525:4.2.0-9.1.2'
compile 'de.jensd:fontawesomefx-materialdesignfont:2.0.26-9.1.2'
compile 'de.jensd:fontawesomefx-materialicons:2.2.0-9.1.2'
compile 'de.jensd:fontawesomefx-octicons:4.3.0-9.1.2'
compile 'de.jensd:fontawesomefx-weathericons:2.0.10-9.1.2'
最后，正如评论中发布的那样，警告只是表明您的 FXML 是使用运行它的 JDK 的较新版本创建的.可以忽略.
Finally, as posted in comments, the warning is just an indication that your FXML was created with a newer version that the JDK running it. It can be ignored.
