无法创建 JavaFX 2.1.0 样本应用程序 - DataApp - 无法创建任务或类型 javafx: com.sun.javafx.tools. ant: application
原标题：cannot build JavaFX 2.1.0 sample application - DataApp - failed to create task or type javafx:com.sun.javafx.tools.ant:application

I am trying to build the DataApp sample application from the JavaFX 2.1.0 sample application pack downloadable from the official JafaFX downloads page:
http://www.oracle.com/technetwork/java/javafx/downloads/index.html

我用Netbeans 7.1.2, JDK6和JavaFX 2.1.0 来交换JDK6。

在 NetBeans 中, 当我右键点击 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?

会不会和蚂蚁有关?

以下几行意味着什么?

The following error occurred while executing this line:

谢谢!

Update: Aparently the problem is solved by manually modifying the Ant build.xml file located in the DataAppClient project root.
I added a taskdef tag at the beginning of the -post-jar target definition and the error was gone:

...

<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}"/>

...

这是否是官方发布此试样应用程序时的错误, 还是我的设置有问题?

问题回答

任何有类似错误的人。 尝试以下的解决方案( 对我有效), 我在这里发现它 < href=" https://groups.google.com/forum/#!msg/efxclipse/ H- ZOVXtaK6g/5yufMqQsZBQJ" rel=“ nofollow” >https://groups.google.com/forum/#msg/efxclipse/ H- ZOVXtaK6g/forum/#!msg/efxclipse/ H- ZOVXtaKK6g/yufMqQsZBQJ

解决方案

我设法通过运行 & gt; 外部工具@gt; 外部工具配置和选择 JRE Tab 来让它发挥作用。 我不得不将执行环境从1.7 改为 CDC-1.0/Foundation-1.0 (jdk1. 7. 0_25) (CDC-1.1) (和CDC-1.1) 也有效 ) 。
