Olá, criei uma aplicação básica no e(fx)clipse, de acordo com o exemplo que encontrei na internet. No entanto ao rodar ela me apresenta uma série de erros, abaixo o meu código:
Método Main

package fx;

import java.io.IOException;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

	@Override
	public void start(Stage stage) throws IOException {
		Parent root = FXMLLoader.load(getClass().getResource("/home/metalicarus/workspace/fx/src/fx/TesteFx.fxml"));
		stage.setTitle("TesteFX FXML");
		stage.setScene(new Scene(root));
		stage.show();
		
		
	}

	public static void main(String[] args) {
		launch(args);
	}
}


 

ColorPickerControll

package fx;
import java.awt.event.ActionEvent;
import java.net.URL;
import java.util.ResourceBundle;

import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.ColorPicker;
import javafx.scene.shape.Circle;


public class ColorPickerControll implements Initializable {
	@FXML private ColorPicker colorPicker;
	@FXML private Circle circle; 
	
	@Override 
	public void initialize(URL location, ResourceBundle resources){
		
	}
	
	@FXML 
	private void select(ActionEvent event){
		circle.setFill(colorPicker.getValue());
	}

}


 

TesteFx.fxml

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.ColorPicker?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.shape.Circle?>


<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.65" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <Circle fx:id="circle" fill="DODGERBLUE" layoutX="287.0" layoutY="200.0" radius="100.0" stroke="BLACK" strokeType="INSIDE" />
      <ColorPicker fx:id="colorPicker" layoutX="421.0" layoutY="42.0" onAction="#select" />
   </children>
</AnchorPane>



 

Abaixo a sequencia de erros :

Olá, obrigado pela resposta, no entanto, o meu arquivo FXML já está na mesma pasta que o método Main, e também já alterei a linha como você mandou e o resultado é o mesmo, erro kkkk . Alguma outra sugestão ?

Opaa. Cara consegui, na verdade o problema não era nem na busca do arquivo, vou explicar.
Eu adicionei um evento ao ColorPicker diretamente pelo SceneBuilder e era isso que estava gerando o conflito. Removi o evento, rodei o programa e funcionou. Mesmo assim agradeço a sua ajuda, abraço !
