在javafx应用程序中使用maven ant插件，如何在javaFX jar中添加依赖项.仍面临类未找到异常 [英] Using maven ant plugin in javafx application, How to add Dependencies in javaFX jar. Still facing class not found exception

问题描述

我使用本指南将我的依赖项添加到主jar 捆绑了依赖项的JavaFX jar 我面临着导致类未找到异常的依赖关系问题.我的Pom就像上面链接中提到的一样.我使用依赖项插件将依赖项复制到目标中的lib文件夹.

I using this guide added my dependencies to main jar JavaFX jar with dependencies bundled i am facing dependencies issue which causing Class not found exception. My Pom is exactly like mentioned in above link. i use dependencies plugin to copy dependencies to lib folder in target.

这是我的堆栈跟踪

使用maven ant插件在maven pom文件中的Maven Ant任务

Maven Ant Task in maven pom file using maven ant plugin

<jfxjar destfile="${project.build.directory}/${project.build.finalName}">
  <fileset dir="${project.build.directory}/classes" />
  <fileset dir="${project.build.directory}/lib/" includes="*.jar" />    

  <application name="${project.name}" mainClass="com.client.main.App" />        
  <resources>
     <fileset dir="${project.build.directory}/lib/" includes="*.jar" />
  </resources>
</jfxjar>

这是我的Fx应用程序类代码

Here is my Fx Application Class code

public class App extends Application {
    /*public static Logger mLogger = LoggerFactory.getLogger(App.class);    */
public static Injector injector;
public static AppHandler mAppHandler;

@Override
public void init() throws Exception {
    // TODO Auto-generated method stub
    super.init();
    injector = Guice.createInjector(new GuiceModule());/*This line cause exception*/
    mAppHandler = injector.getInstance(AppHandler.class);
    if(mAppHandler!=null)
        mAppHandler.startHandler();
}

@Override
public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getResource("/fxml/FXMLDocument.fxml"));

    Scene scene = new Scene(root);
    scene.getStylesheets().add("/styles/style.css");
    stage.setTitle("RPAS Java Client");
    stage.getIcons().add(new Image("/images/RPAS Java Client.png"));
    stage.setScene(scene);
    stage.show();
}

@Override
public void stop() throws Exception {
    mAppHandler.stopHandler();
} 



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

}

这是我的理解

现在我了解的是我的依赖项未正确加载.蚂蚁的罐子制作"任务使得罐子没有任何问题.当我双击通过异常.我打开了罐子，这是我的清单

Now what i understand is my dependencies are not properly loading. ant "jar making" task makes jar without any issues. when i double click it through exception. I opened the jar and here is my Manifest

Manifest-Version: 1.0
JavaFX-Version: 2.2
JavaFX-Application-Class: com.client.main.App
JavaFX-Class-Path: guice-3.0.jar hamcrest-core-1.3.jar javax.inject-1.jar log4j-1.2.15.jar slf4j-api-1.7.7.jar slf4j-log4j12-1.7.7.jar 
Created-By: JavaFX Packager
Main-Class: com/javafx/main/Main

我还想知道我何时看到jar制作过程将com.javafx.main.Main.java文件自动添加到代码中，该文件首先检查运行时(JRE和FX)，然后是否全部成功调用com.sun.javafx .Application.LauncherImp.

I also wonder when i saw that jar making process add com.javafx.main.Main.java file to the code automatically which first check Run time(JRE and FX) and then if all successful invoke the com.sun.javafx.Application.LauncherImp .

有人可以帮助我吗?

我已经解决了该问题.在此链接上查看我的最终Pom
