我正在尝试从可从官方 JafaFX 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，我得到以下输出：

有人知道这个错误吗？

它可能与 Ant 有某种关系吗？

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：显然问题是通过手动修改位于 DataAppClient 项目根目录中的 Ant build.xml 文件来解决的。
我在 -post-jar 目标定义的开头添加了一个 taskdef 标签，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->外部工具_>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 也可以工作）。

错误-
