netbeans ide中没有错误，但java.lang.ClassNotFoundException:org.netb

Question

maven应用程序在netbeans ide上运行时没有出现错误，clean和build也在运行时没有出错，我没有提到的依赖项是：(mongodb，mongodb驱动程序，mysql，itext(我试着启动4j，.exe文件没有打开。这是POM文件：

我试着在lib/中创建一个awtextra文件夹，并从external/复制其中的absolutelayout文件夹，但没有成功。这是命令行错误：

OneDriveDesktopbilling-systemtarget>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)
