我正在尝试从可从JafaFX官方下载页面下载的JavaFX 2.1.0示例应用程序包构建DataApp示例应用程序：
http://www.oracle.com/technetwork/java/javafx/downloads/index.html
我正在使用 Netbeans 7.1.2、JDK6 和 JavaFX 2.1.0 for JDK6。
在 NetBeans 中，当我右键单击 DataApp 服务器并从上下文菜单中选择"运行"时，将得到以下输出：

有人对这个错误有任何想法吗？
会不会和蚂蚁有某种关系？
以下几行是什么意思？

谢谢！
更新：通过手动修改位于 DataAppClient 项目根目录中的 Ant 构建.xml文件，可以解决此问题。
我在 -post-jar 目标定义的开头添加了一个 taskdef 标签，但错误消失了：
...
<target name="-post-jar" depends="-init-javafx, -jfx-copylibs">
<taskdef resource="com/sun/javafx/tools/ant/antlib.xml"
uri="javafx:com.sun.javafx.tools.ant"
classpath="d:Softjavafx_sdk_2.1libant-javafx.jar" />
<!-- Move preloader out of libs -->
<move file="${dist.dir}/lib/DataAppPreloader.jar" todir="${dist.dir}"/>
...
这可能是此示例应用程序的正式版本中的错误，还是我的设置有问题？

任何有类似错误的人。尝试以下解决方案（它对我有用），我在这里找到了它 https://groups.google.com/forum/#!msg/efxclipse/H-ZOVXtaK6g/5yufMqQsZBQJ
解决方案
我设法通过转到运行>外部Tools_>外部工具配置并选择 JRE 选项卡来使其工作。 我不得不将执行环境从 1.7 更改为 CDC-1.0/Foundation-1.0 （jdk1.7.0_25）（CDC-1.1 也可以）。
