Why is Gluon control CardPane not found when mvn gluonfx:nativerun?

Question

Here's the FXML file:

<?import com.gluonhq.charm.glisten.control.CardPane?>
<?import com.gluonhq.charm.glisten.mvc.View?>
<?import javafx.scene.layout.BorderPane?>

<View fx:id="myView" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="600.0" prefWidth="335.0" xmlns="http://javafx.com/javafx/16" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.mydomain.view.MyPresenter">
   <center>
      <BorderPane prefHeight="591.0" prefWidth="322.0" BorderPane.alignment="CENTER">
         <center>
            <CardPane fx:id="cardPane" prefHeight="465.0" prefWidth="333.0" />
         </center>
      </BorderPane>
   </center>
</View>

If I mvn gluonfx:run then it works fine. I see the CardPane. I can add cards to it. I see it update its list of cards as expected.

But if I then try to mvn gluonfx:nativerun I fail with ClassNotFoundException: com.gluonhq.charm.glisten.control.CardPane

adding to Javateer, maybe just simply add to the reflection lists all your imports:

                    <reflectionList>
                        <list>javafx.scene.control.ListView</list>
                        <list>javafx.scene.control.SplitPane</list>
                        <list>javafx.scene.control.ButtonBar</list>
                        <list>javafx.scene.layout.AnchorPane</list>
                        <list>javafx.scene.layout.ColumnConstraints</list>
                        <list>javafx.scene.layout.GridPane</list>
                        <list>javafx.scene.layout.HBox</list>
                        <list>javafx.scene.control.Menu</list>
                        <list>javafx.scene.control.MenuBar</list>
<!--                        <list>javafx.scene.control.MenuItem</list>-->
                        <list>javafx.scene.layout.RowConstraints</list>
                        <list>org.travelonline.guidemo.persongui.FXApplication</list>
                        <list>org.travelonline.guidemo.persongui.FXController</list>
                    </reflectionList>

based on my imports in fxml file below:

    <?import javafx.scene.control.Button?>
    <?import javafx.scene.control.Label?>
    <?import javafx.scene.control.ListView?>
    <?import javafx.scene.control.Menu?>
    <?import javafx.scene.control.MenuBar?>
    <?import javafx.scene.control.MenuItem?>
    <?import javafx.scene.control.SplitPane?>
    <?import javafx.scene.control.TextArea?>
    <?import javafx.scene.control.TextField?>
    <?import javafx.scene.control.ButtonBar?>
    <?import javafx.scene.layout.AnchorPane?>
    <?import javafx.scene.layout.ColumnConstraints?>
    <?import javafx.scene.layout.GridPane?>
    <?import javafx.scene.layout.HBox?>
    <?import javafx.scene.layout.RowConstraints?>

Thanks @JoséPereda for nudging me where to go look next. New questions came up along the way but I finially got the app working in native run mode.

However, I then realized my noob mistake. I had forgotten to keep going back to the project pom file to update the reflectionList of the gluon plugin. So, I undid the messy fix with underlying config files and then just updated as follows below. I show you the platform widgets I needed to mention per the stacktrace feedback I was seeing. I also listed my own classes but don't bother showing those here too.

            <artifactId>gluonfx-maven-plugin</artifactId>
            <version>${gluonfx.plugin.version}</version>
            <configuration>
                <reflectionList>
                    <list>javafx.scene.control.DatePicker</list>
                    <list>com.gluonhq.charm.glisten.control.CardPane</list>
