无法构建JavaFX 2.1.0示例应用程序 - DataApp - 无法创建任务或输入javafx：com.sun.javafx.tools.ant：application

Question

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

I am using Netbeans 7.1.2, JDK6 and JavaFX 2.1.0 for JDK6.

In NetBeans, when I right-click on the DataApp server and select Run from the context menu, I get the following output:

Does anybody have any idea about this error?

Could it be somehow related to Ant ?

What do the following lines mean?

The following error occurred while executing this line:

Thank you!

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

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

...

Can this be an error in the official release of this sample application, or something is wrong with my setup ?

Answer 2

Anyone who has a similar error. Try the following solution (it worked for me), I found it here https://groups.google.com/forum/#!msg/efxclipse/H-ZOVXtaK6g/5yufMqQsZBQJ

The Solution

I managed to get it to work by going to Run->External Tools_>External Tools Configurations and selecting JRE Tab. I had to change the Execution environment from 1.7 to CDC-1.0/Foundation-1.0 (jdk1.7.0_25) (and CDC-1.1 also works).

The Error-

BUILD FAILED
