我想從JavaFX 2.1.0示例應用程序構建DataApp示例應用程序從官方JafaFX下載頁面下載包：
http://www.oracle.com/technetwork/java/javafx/downloads/index.html無法構建JavaFX 2.1.0示例應用程序 - DataApp - 未能創建任務或類型javafx：com.sun.javafx.tools.ant：應用程序
我使用NetBeans 7.1.2，JDK6和JavaFX 2.1.0 JDK6。
在NetBeans中，當我DataApp服務器上單擊鼠標右鍵，然後從上下文菜單中選擇運行，我得到下面的輸出：

BUILD FAILED (total time: 6 seconds)
有誰知道這個錯誤的任何想法？
它可能是某種程度上與螞蟻有關嗎？
以下幾行代表什麼意思？
The following error occurred while executing this line:

謝謝！
更新： 另外，通過手動修改位於DataAppClient項目根目錄中的Ant build.xml文件可以解決問題。
我在-post-jar目標定義的開頭加了標籤的taskdef和錯誤走了：
...
<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}"/>
...
可這是在此示例應用程序的正式發佈錯誤，或者什麼是錯用我的設置？
DataApp需要基礎設施來進行設置。項目中有README，請看一下。 –
我已閱讀文檔，並執行了自述文件中顯示的步驟。 –
哦，對不起，錯過了一個實際的問題。 DataAppClient應該基於NetBeans中的「Default JavaFX Platform」，其中包括例如ant任務定義。如果您沒有設置該平臺或未將其用於DataAppClient項目，則可以選擇手動添加taskdef。哪些工作適合你。 –
