【问题描述】：

我正在尝试使用 JavaFX WebEnginge 加载浏览器以如下所示摆动

SwingUtilities.invokeLater(() -> InitGUI());

final JFXPanel jfxPanel = new JFXPanel();
panel.add(jfxPanel);

Platform.runLater(() -> {
    WebView webView = new WebView();
    jfxPanel.setScene(new Scene(webView));
    webView.getEngine().load("https://pl.wikipedia.org/wiki/London");
});

网站在我的 Swing 应用程序中显示，但是当我在加载的网站上移动鼠标时，IntelliJ 抛出

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: 'void com.sun.javafx.embed.EmbeddedSceneInterface.mouseEvent(int, int, boolean, boolean, boolean, int, int, int, int, boolean, boolean, boolean, boolean, boolean)'

我应该在某处添加 mouseEventListeners 吗？整个 GUI 在我的 Main 类中，没有任何按钮，只有 JLabels 和 javaFX 的这个 webView。每次我移动鼠标/单击时，只会在此 webView 上发生错误。其他摆动组件不会抛出任何东西。

@编辑我还没有发布第一行异常

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: 'void com.sun.javafx.embed.EmbeddedSceneInterface.mouseEvent(int, int, boolean, boolean, boolean, int, int, int, int, boolean, boolean, boolean, boolean, boolean)'

【问题讨论】：

确保在编译和运行时路径上都有所有必要的模块（控件、swing、fxml、web）。如果是这样并且仍然卡住，请提供 minimal reproducible example 来演示问题。无关：java命名约定，请
对我来说很好。我在 Windows 10（64 位）上使用来自 OpenJFX 和 Eclipse 2020-09（4.17.0）的 Oracle JDK 15 和 JavaFX 15

【解决方案1】：

问题已解决

我已经添加了

--module-path /Users/<user>/javafx-sdk-15/lib --add-modules=javafx.controls,javafx.fxml,javafx.web,javafx.swing

在运行>编辑配置>虚拟机选项

【解决方案2】：

添加模块并没有解决我的问题——我已经添加了它们。

解决方案

没有在 JavaFX Gradle Plugin 中指定 JavaFX 版本为我解决了这个问题。

javafx {
    version = "11.0.1" // ← I removed this line
    modules = [ 'javafx.controls', ...
}

详情

我试图使用CalendarFX；原来我尝试使用的版本 11.8.3 使用 JavaFX 13.0.1。

一旦我升级或删除了我所包含的 JavaFX 版本，异常就消失了。

完全异常

【解决方案3】：

我正在使用 Maven 构建，我的解决方案也与依赖项的版本有关，但我没有删除版本，而是将每个 javafx 库升级到最新的可用版本。在此之前使用的是导致问题的旧版本，所以在pom.xml 中我编辑了<version> 标签。

之前：

        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-controls</artifactId>
            <version>13</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-fxml</artifactId>
            <version>13</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-swing</artifactId>
            <version>11</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-base</artifactId>
            <version>13</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-graphics</artifactId>
            <version>13</version>

之后：

        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-controls</artifactId>
            <version>17.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-fxml</artifactId>
            <version>17.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-swing</artifactId>
            <version>17.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-base</artifactId>
            <version>17.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-graphics</artifactId>
            <version>17.0.1</version>
        </dependency>
