Question

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Run时，我得到以下输出：

有人对这个错误有任何想法吗？

它可能与Ant有什么关联吗？

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，通过手动修改位于DataAppClient项目根目录中的Ant build.xml文件可以解决问题我在-post-jar目标定义的开头添加了一个taskdef标记，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正式版本中的错误，或者我的设置有问题吗？

通常通过手动修改位于DataAppClient项目根目录中的Ant build.xml文件来解决问题我在-post-jar目标定义的开头添加了一个taskdef标记，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}"/>

...

任何有类似错误的人。尝试以下解决方案（它对我有用），我在https://groups.google.com/forum/#!msg/efxclipse/H-ZOVXtaK6g/5yufMqQsZBQJ

找到了它

解决方案

我设法通过转到Run-＆gt;外部工具_＆gt;外部工具配置并选择JRE选项卡来实现它。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）（并且CDC-1.1也可以）。

错误 -
