Question

我正在开发一个基于OSGI（Equinox）的系统，我遇到了JavaFX，我正在尝试e（fx）clipse {OSGI bundle project}，我写了一个简单的测试项目，但是它给了我一些编译错误。我有一个主要课程：

import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class main extends Application {
    private static main _main ;
    public main () {
        _main = this;
    }
    public static main Get_Main(){
        return _main;
    }
    @Override
    public void start(Stage primaryStage) 
    {
        try 
        {
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(main.class.getResource("fxml.fxml"));

            primaryStage.setScene(new Scene(loader.load()));
        } 
        catch (IOException e) 
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

我有一个FXML的控制器

import javafx.event.EventHandler;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.AnchorPane;

public class controller {
    @FXML
    private AnchorPane _AnchorPane;
    @FXML
    private Button _Btn;

    @FXML
    private void initialize() {
        _AnchorPane.setOnMouseClicked(new EventHandler<MouseEvent>() {
            @Override
            public void handle(MouseEvent event) {
                _AnchorPane.setStyle("-fx-background-color:red");
            }
        });
    }

    @FXML
    private void _BtnClick() {
        _AnchorPane.setStyle("-fx-background-color:blue");
    }
}

和捆绑的Activator

import javafx.stage.Stage;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class aCTIVATOR implements BundleActivator {
    private Stage _stage = new Stage();
    private main _main;
    @Override
    public void start(BundleContext context) throws Exception {
        _main = main.Get_Main();
        _main.start(_stage);
    }

    @Override
    public void stop(BundleContext context) throws Exception {
        _stage.close();
    }
}

这是我的清单文件：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: 
Bundle-SymbolicName: root
Bundle-Version: 1.0.0.qualifier
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Import-Package: javafx.animation;version="2.0.0",
 javafx.application;version="2.0.0",
 javafx.beans;version="2.0.0",
 javafx.beans.binding;version="2.0.0",
 javafx.beans.property;version="2.0.0",
 javafx.beans.value;version="2.0.0",
 javafx.collections;version="2.0.0",
 javafx.concurrent;version="2.0.0",
 javafx.event;version="2.0.0",
 javafx.fxml;version="2.0.0",
 javafx.geometry;version="2.0.0",
 javafx.scene;version="2.0.0",
 javafx.scene.chart;version="2.0.0",
 javafx.scene.control;version="2.0.0",
 javafx.scene.control.cell;version="2.0.0",
 javafx.scene.effect;version="2.0.0",
 javafx.scene.image;version="2.0.0",
 javafx.scene.input;version="2.0.0",
 javafx.scene.layout;version="2.0.0",
 javafx.scene.media;version="2.0.0",
 javafx.scene.paint;version="2.0.0",
 javafx.scene.shape;version="2.0.0",
 javafx.scene.text;version="2.0.0",
 javafx.scene.transform;version="2.0.0",
 javafx.scene.web;version="2.0.0",
 javafx.stage;version="2.0.0",
 javafx.util;version="2.0.0"
Bundle-Activator: aCTIVATOR
Require-Bundle: org.eclipse.osgi;bundle-version="3.10.0"

所以当我进入运行配置时，我选择OSGI-FrameWork并选择

项目
org.eclipse.osgi
org.eclipse.fx.javafx
org.eclipse.fx.osgi

最后它给出了我的编译错误：

!!!!!!!（这很长）那么对此有什么想法或帮助吗？

Answer 1

你看到＆＃34; java.lang.NoClassDefFoundError＆＃34;是Equinox不会参考Ext-classpath，而且很可能你不会告诉Equinox使用我们的适配器钩子，这使得equinox可以参考这条路径。

您需要做的是：

确保您的启动中包含org.eclipse.fx.osgi片段
确保在启动配置中将-Dosgi.framework.extensions = org.eclipse.fx.osgi作为VM参数传递
（更新）使用-Dorg.osgi.framework.bundle.parent = ext

现在我已经回答了你的真实问题。我不能最后说明你的询问和回复人的风格。这不好，我多次想过我是否应该回答。不要在你的问题中加上感叹号并回复，然后再让某人思考，如果这是与试图帮助你的人交谈的正确方法！
