无法构建JavaFX 2.1.0示例应用程序-DataApp- 创建任务失败或键入javafx：com.sun.javafx.tools.ant：application

Question

我正在尝试从JavaFX

2.1.0示例应用程序包构建DataApp示例应用程序，可从官方JafaFX下载页面下载该文件： http

//www.oracle.com/technetwork/java/javafx/downloads/index.html

我正在为JDK6使用Netbeans 7.1.2，JDK6和JavaFX 2.1.0。

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：

BUILD FAILED (total time: 6 seconds)

有人对此错误有任何想法吗？

可能与Ant有某种联系吗？

以下几行是什么意思？

The following error occurred while executing this line:
D:\Soft\javafx-samples-2.1.0\src\DataApp\DataAppClient\build.xml:48: Problem: failed to create task or type javafx:com.sun.javafx.tools.ant:application

谢谢！

更新：显然，可以通过手动修改位于DataAppClient项目根目录中的Ant build.xml文件来解决该问题。
我在-post-jar目标定义的开头添加了taskdef标记，该错误消失了：

...

<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:\Soft\javafx_sdk_2.1\lib\ant-javafx.jar" />

    <!-- Move preloader out of libs -->
    <move file="${dist.dir}/lib/DataAppPreloader.jar" todir="${dist.dir}"/>

...

这可能是该示例应用程序的正式发行版中的错误，还是我的设置有问题？
