Question

目前我正在尝试将我的代码导出到可以从桌面运行的Jar文件中。我遇到的问题是，当我尝试运行它时，某些按钮不起作用，在 NetBeans 中运行相同的程序时则不然。

该程序是使用 sikulix 库和 swingworker 扩展程序的机器人。为什么这可能很重要，因为在尝试代码中的按钮时，那些使用swingworker的代码量很大的代码恰好是那些无效的代码。

我的导出方法基于以下指南：http://www.oracle.com/technetwork/articles/javase/index-139904.html

整个导出过程按预期工作（或至少如教程所示） - 但某些功能在导出的版本中不起作用。所以，我向你提出的问题是：什么可能导致程序部分工作？

使用CMD运行程序并按下其中一个按钮后，发生以下错误：
