线程“JavaFX 应用程序线程”中的 JavaFx 异常 线程“主”java.lang.NoClassDefFoundError 中的异常：org/apache/log4j/Logger

该应用程序在 Eclipse 和 IntelliJ 以及“ant run”中运行得非常好。只有当我以 Windows cmd 运行时才会出现以下错误：

java -jar TheApp.jar

这似乎是一个 -classpath 问题，但我已经花了一天多的时间，但仍然得到同样的错误。

我正在附加 build.xml，它也可以完美运行：

<?xml version="1.0"?>

<project name="App" default="all" basedir=".">

    <property name="src"   value="./src"/>

    <property name="build" value="./build"/>

    <property name="lib"   value="./lib"/>

    <property name="dest"   value="./dest"/>

    <property name="main-class"  value="com.th.app.ui.Login"/>

    <path id="classpath">

        <fileset dir="${lib}" includes="**/*.jar"/>

    </path>

    </target>

    <target name="copy-file">

        <copy todir="${dest}"><fileset dir="${build}"/></copy>

    </target>

</project>

这是我的第一个 JavaFx 项目，我正在努力完成它。

请提供帮助，非常感谢任何见解。
