我正在尝试使用JavaFX WebEngineer加载浏览器，以使如下
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");
});
网站显示在我的swing应用程序中，但当我在加载的网站上移动鼠标时，IntelliJ会抛出

我应该在某个地方添加mouseEventListeners吗？整个GUI都在我的Main类中，没有任何按钮，只有JLabels和这个来自javaFX的webView。每次移动鼠标/单击时，只有此webView才会出现错误。其他挥杆部件不会投掷任何东西。
@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)'
问题已解决
我添加了
--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>VM选项
添加模块并没有解决问题——我已经添加了它们。
解决方案
没有在JavaFX Gradle插件中指定JavaFX版本为我解决了这个问题。
javafx {
version = "11.0.1" // ← I removed this line
modules = [ 'javafx.controls', ...
}
详细信息
我试图使用CalendarFX；事实证明，我尝试使用的版本11.8.3使用的是JavaFX13.0.1。
一旦我升级或删除了我包含的JavaFX版本，异常就消失了。
完全异常

我正在使用Maven进行构建，我的解决方案也与依赖关系的版本有关，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，使用了导致问题的旧版本，因此在pom.xml中，我编辑了<version>标记。
之前：
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-controls</artifactId>
<version>13</version>
