Question

关于一些问题，我创建了一个jar文件但是当我尝试在提示符中执行它时出现此错误：

错误：发生了JNI错误，请检查您的安装和再次尝试线程中的异常＆＃34; main＆＃34; java.lang.NoClassDefFoundError： COM / itextpdf /布局/元件/ IBlockElement

但如果我在Netbeans中运行它就会启动。为什么呢？

这是我的POM.xml文件：

您构建的jar不包含您编译的依赖项。您可以使用maven程序集插件生成依赖项包，然后配置类路径，或者只构建一个包含所有依赖项的jar：How can I create an executable JAR with dependencies using Maven?
