我正在编写一段不错的代码，效果很好。它无处不在停止了工作，我让其他人对其进行了测试，并确认它也不适用于他们。我还尝试回滚代码，甚至几天后也没有任何变化。我放了一堆System.out.Println（）来帮助我调试代码在哪里中断并收到NullPointerException。它发生在initComponents（）处。更奇怪的是，当我使用GUI Builder时，initComponenets中的任何内容都是使用NetBeans生成的。我只有15行，称为“ Alive＃”，因此当程序崩溃时，我可以轻松地在日志中看到它们。崩溃之前我只能看到活着的14，从来没有达到活着的15。我只能在下面放一个片段。 https://pastebin.com/ibPfDxMY具有完整的initComponents（）。更让人好奇的是，当从NetBeans运行它时，它始终如一地工作，只有当我通过双击或终端运行.jar文件时，才会出现此错误。
我尝试运行空白的测试框架，并且运行得很好。

答案 0 :(得分：0)
我认为此行会导致NullPointerException：
logoButton.setIcon(new javax.swing.ImageIcon(getClass().getResource("/AQWBot/Icons/icon.png"))); // NOI18N
我也遇到了这个问题，例如，当我将整个路径传递到图像时，它就对我有用：（前提是图像位于软件包at.daselias.resources.icons中）
logoButton.setIcon(new javax.swing.ImageIcon(getClass().getResource("/at/daselias/resources/icons/icon.png"))); // NOI18N
总是仅在jar文件中而不是在IDE中发生该问题。
编辑：当然，要按我建议的行解决问题还不够，您必须在加载资源的所有行中都进行此操作。
