I had the same issue. Firstly I wrote my controller class on the fxml file manually, after that annotated @FXML at the top of the each method on the controller class than figured it out.

According to this answer the only is to put in the same folder where your FXML file exist,the problem is from scenebuilder it has a limitation .

chekc out the link below for more details

SceneBuilder 2: Do controller classes need to necessarily be in the same folder as the view FXML files?

Define your controller class in your fxml file : 

<AnchorPane xmlns:fx="http://javafx.com/fxml/1" id="GridPane" prefHeight="400.0" prefWidth="600.0" styleClass="mainFxmlClass" fx:controller="yourpackage.yourControllerClass">
   <children>
     ...
   </children>
</AnchorPane>
