Question

我在javaFX中开发应用程序，并且最近有必要使其跨平台。我做了一些研究，发现了胶子插件，我认为这是重新使用已经完成的代码的好方法，并且不需要通过它来开始新的东西。在我的javaFX项目中，它编译并运行没有任何问题但是当我尝试在gluon项目上编译相同的代码时它返回此错误：

这是我的MainApp：

public class MainApp extends Application {

    private Stage primaryStage;
    private BorderPane rootLayout;

    @Override
    public void start(Stage primaryStage) {
        this.primaryStage = primaryStage;
        this.primaryStage.setTitle("Title");

        initRootLayout();
        showMainLayout();
    }

    public void initRootLayout() {
        try {
            // Load root layout from fxml file.
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(MainApp.class.getResource("view/RootLayout.fxml"));
            rootLayout = (BorderPane) loader.load();

            // Show the scene containing the root layout.
            Scene scene = new Scene(rootLayout);
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public void showMainLayout(){
        try{
            // Load Technic Page.
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(MainApp.class.getResource("view/MainLayout.fxml"));
            AnchorPane mainLayout = (AnchorPane) loader.load();

            rootLayout.setCenter(mainLayout);

        }catch(IOException e){
            e.printStackTrace();
        }
    }

第40行是：rootLayout = (BorderPane) loader.load();

这是build.gradle：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.0-b10'
    }
}

apply plugin: 'java'

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar']) 
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
}

mainClassName = 'com.resopark.MainApp'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        androidSdk = 'C:/Users/JSoares/AppData/Local/Android/sdk'
    }
}

我在Windows 10中使用eclipse

任何人都可以帮助我吗？提前致谢。（对不起我的英文）
