javafx8 应用程序可执行文件

Question

我在 Eclipse 中使用javafx8 创建了一个媒体播放器。 jar 文件生成正确，但是当我运行可执行文件时，出现以下消息

这是我的build.xml。我试图做一些修改，但它不起作用。我正在使用jdk.1.8.0

    <taskdef resource="com/sun/javafx/tools/ant/antlib.xml"
        uri="javafx:com.sun.javafx.tools.ant"

请帮帮我。

Answer 1

对话框表明您的主类中发生了异常。您是否捕获了主类可能抛出的所有可能异常？如果 IDE 中没有生成异常，您可能需要检查所有外部库和资源是否都在类路径中。

Answer 2

信息太少，无法给出准确答案，但您可以尝试在主类中实现日志记录，这样您就可以查看日志文件，抛出什么样的异常以及原因。
