Composant personnalisé JavaFX Gluon Scene Builder avec dépendance externe

Question

J'ai deux projets: Composants et MyApp.

projet Composants deux fichiers:

mycomponents/MyComponent.fxml 
mycomponents/MyComponent.java 

MyComponent.fxml utilise ikonli et ikonli-core-1.9.0.jar, ikonli-javafx-1.9.0.jar et ikonli-material-pack-1.9.0.jar sont inclus dans le projet (je pense que pour la compilation projet ikonli-javafx-1.9.0.jar suffit)

MyComponent.fxml:

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

<?import javafx.scene.control.Button?> 
<?import org.kordamp.ikonli.javafx.FontIcon?> 


<fx:root type="javafx.scene.layout.AnchorPane" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.111"> 
    <children> 
     <Button mnemonicParsing="false"> 
     <graphic> 
      <FontIcon iconLiteral="gmi-check-circle" iconSize="24" /> 
     </graphic> 
     </Button> 
    </children> 
</fx:root> 

MyComponent.java:

package mycomponents; 

import java.io.IOException; 
import javafx.fxml.FXMLLoader; 
import javafx.scene.layout.AnchorPane; 

public class MyComponent extends AnchorPane { 
    public MyComponent() { 
     FXMLLoader loader = new FXMLLoader(MyComponent.class.getResource("MyComponent.fxml")); 
     loader.setRoot(this); 
     loader.setController(this); 
     try { 
      loader.load(); 
     } catch (IOException exception) { 
      throw new RuntimeException(exception); 
     } 
    } 
} 

Le projet compile avec succès et je peux ouvrir MyComponent.fxml en scène Builder (parce que j'importer trois ikonli jarres en scène Builder (via la recherche de référentiel)). Après la compilation de projet composants I importer Components.jar en scène Builder, et la situation de la Mangeoire Library est:

projet MyApp ont trois fichiers:

myapp/FXMLDocument.fxml 
myapp/FXMLDocumentController.java 
myapp/MyApp.java 

FXMLDocument.fxml:

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

<?import javafx.scene.control.Label?> 
<?import javafx.scene.layout.AnchorPane?> 
<?import mycomponents.MyComponent?> 

<AnchorPane xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.111" fx:controller="myapp.FXMLDocumentController"> 
    <children> 
     <MyComponent /> 
    </children> 
</AnchorPane> 

FXMLDocumentController.java:

package myapp; 

import java.net.URL; 
import java.util.ResourceBundle; 
import javafx.fxml.Initializable; 

public class FXMLDocumentController implements Initializable { 
    @Override 
    public void initialize(URL url, ResourceBundle rb) { 
     // TODO 
    }  
} 

MyApp.java:

package myapp; 

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

public class MyApp extends Application { 
    @Override 
    public void start(Stage stage) throws Exception { 
     Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml")); 
     Scene scene = new Scene(root); 
     stage.setScene(scene); 
     stage.show(); 
    } 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) { 
     launch(args); 
    }  
} 

I inclus trois ikonli pots et Components.jar. Les projets se compilent bien et je peux lancer une application et tout fonctionne.

Mais quand je veux ouvrir FXMLDocument.fxml avec Scene Builder je reçois cette erreur:

Answer 1

Salut Im face au même problème, comme une solution de contournement j'extraire les dépendances de .jar et y compris alors im mon composant .pot.

J'utilise gradle pour construire, c'est un snipet de la build.gradle où les choses se passent.

Le 'XXX' est le nom de ma bibliothèque;

... 
dependencies { 
... 
    compile 'br.com.emorgado:XXX:1.0.0-SNAPSHOT' 
... 
} 

task extractTransitiveDependencies(type: Copy) { 
    into "$buildDir/classes/main" 
    from { 
     configurations.compile.filter{ 
      it.name.startsWith('XXX') 
     } 
     .collect { 
      zipTree(it) 
     } 
    } 
} 

jar.dependsOn extractTransitiveDependencies 

jar { 
    doFirst {  
    copy{ 
     from("$buildDir/output/lib/br/com/emorgado/"){ 
     exclude 'META-INF' 
     } 
     into("/br/com/emorgado/") // <- this is my component folder 
} 
...
