使用java-classpath命令执行主类时发生NoClassDefFoundError

我有一个Maven项目，其中有一个

Main.java

类，它包含我想从Windows命令提示符执行的

Main（）

方法。我正在使用下面的命令执行它，但它失败并显示错误消息（如下所示）。这个程序在IDE中运行良好

stackoverflow的类似问题已列出，但未提供解决方案。它只是详细地解释了这个问题

请导游

执行主类的命令：

java -classpath target\jobchain-dataloader.jar com.ebayenterprise.ecp.jobs.Main

C:\office-data\v11-Projects\jobchain-dataloader>java -classpath target\jobchain-dataloader.jar com.ebayenterprise.ecp.jobs.Main

通过在pom中添加以下插件，可以让程序正常工作

第一个依赖项在jar中创建

META-INF/manifest.mf

文件，第二个依赖项在现有

target

目录中创建

lib

文件夹，并复制其中的所有依赖项
