<p>I have an issue while I open the abc.fxml file in Scene builder is shows this dialog box:</p>

<p><a href="https://i.stack.imgur.com/tG6jm.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tG6jm.png" alt="enter image description here"></a></p>

<p><strong>This is a abc.fxml code:</strong></p>

<pre><code>`&lt;?xml version="1.0" encoding="UTF-8"?&gt;

&lt;?import com.jfoenix.controls.JFXButton?&gt;
&lt;?import javafx.scene.layout.AnchorPane?&gt;


&lt;fx:root fx:id="w" prefHeight="400.0" prefWidth="400.0" type="AnchorPane" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.65"&gt;
   &lt;children&gt;
      &lt;JFXButton fx:id="w1" layoutX="138.0" layoutY="243.0" /&gt;
      &lt;JFXButton fx:id="w2" layoutX="256.0" layoutY="230.0" /&gt;
   &lt;/children&gt;
&lt;/fx:root&gt;`
