Question

我是Javafx的初学者，我创建了一个桌面应用程序，我在我的应用程序中使用 derby.jar 和 datepicker.jar 文件netbeans推出工作正常。但是当我创建它的 exe 文件包时， exe 在启动时显示以下错误。

JavaFX Luncher错误

请有人指导我。

虽然我在 build.xml

中使用了以下脚本

       <target name="-post-jfx-deploy">
     <fx:deploy width="${javafx.run.width}" height="${javafx.run.height}" 
              nativeBundles="all"
              outdir="${basedir}/${dist.dir}" outfile="${application.title}">
      <fx:application name="${application.title}" 
                      mainClass="${javafx.main.class}"/>
      <fx:resources>
          <fx:fileset dir="${basedir}/${dist.dir}"
                      includes="*.jar"/>


      </fx:resources>
      <fx:info title="${application.title}" 
               vendor="${application.vendor}"/>
    </fx:deploy>          
 </target>

这是我正在使用的支持JavaFX的Ant构建文件，使用Proguard进行模糊处理，并发布本机安装程序：
