【问题描述】：
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：

Action: Check that any <presetdef>/<macrodef> declarations have taken place.

BUILD FAILED (total time: 6 seconds)
有人知道这个错误吗？
会不会和 Ant 有某种关系？
以下几行是什么意思？

谢谢！
更新：
显然，通过手动修改位于 DataAppClient 项目根目录中的 Ant build.xml 文件解决了这个问题。
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？
【问题讨论】：
-
DataApp 需要设置基础设施。项目中有README，看一下。
-
我已经阅读了文档并执行了自述文件中显示的步骤。
-
哦，抱歉，错过了一个实际问题。 DataAppClient 应该基于 NetBeans 中的“默认 JavaFX 平台”，其中包括例如 ant 任务定义。如果您没有设置该平台或没有将其用于 DataAppClient 项目，您可以选择手动添加 taskdef。哪个对你有用。

您能否用您找到的信息回答您自己的问题并接受这样的回答（这是常见做法，因此其他用户可以看到此问题已回答）
-
抱歉这么久才回答这个问题，我还在学习如何正确使用这个网站。
