netbeans ide 中没有错误，但 java.lang.ClassNotFoundException: org.netbeans.lib.awtextra.AbsoluteLayout ERROR 当 java -jar jarfilename.jar

如何解决netbeans ide 中没有错误，但 java.lang.ClassNotFoundException: org.netbeans.lib.awtextra.AbsoluteLayout ERROR 当 java -jar jarfilename.jar

maven 应用程序在 netbeans ide 上运行没有错误，clean 和 build 也没有错误运行，我没有提到的依赖项是：（mongodb、mongodb 驱动程序、MysqL、itext）我试过launch4j，.exe 文件没有打开。 这是 POM 文件：

我尝试在 lib/ 中创建一个 awtextra 文件夹并从 external/ 复制其中的 absolutelayout 文件夹，但它不起作用。这是命令行错误：

OneDrive\Desktop\billing-system\target>java -jar billing-system-1.0-SNAPSHOT.jar
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/netbeans/lib/awtextra/AbsoluteLayout
        at login.initComponents(login.java:41)
        at login.<init>(login.java:21)
 

解决方法

问题已解决 1.安装maven 2.java JAVA_HOME 增加配置 3.添加配置到maven MAVEN_HOME 4.在pom文件中添加了目标插件 5.在jar文件中添加了使用dependencier构建 6.使用launch4j作为exe文件 我的 pom 文件：
