Problem with webEngine JavaFX using with swing

I'm trying to load browser using JavaFX WebEnginge to swing as below

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");
});

Websites shows in my swing application but when I'm moving a mouse on the loaded website IntelliJ throws

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)'

I should add mouseEventListeners somewhere? Whole GUI is in my Main class, without any buttons, just JLabels and this webView from javaFX. Error occurs only on this webView every time I move mouse/click. Other swing components don't throw anything.

@edit I haven't posted first line of exception

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)'

I am building with Maven, and my solution also had something to do with versions of dependencies, but instead of deleting the version, I upgraded every javafx library to the newest available version. Before that older versions were used which were the cause of the problem so in pom.xml I edited the <version> tags.

Before:

        <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>

After:

        <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>

Adding the modules didn't solve it for me—I had already added them.

A Solution

Not specifying a JavaFX version in the JavaFX Gradle Plugin solved it for me.

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

Details

I was trying to use CalendarFX; turns out the version I was trying to use, 11.8.3, uses JavaFX 13.0.1.

Once I upped or removed the JavaFX version I was including, the exception went away.
