在执行可运行jar文件（java代码）时，我得到java.lang.reflect.InvocationTargetException
作为我的一个项目任务的一部分，我需要从Excel中读取一些数据，通过Sikuli使用这些数据处理应用程序，然后将结果写回Excel。
它在Eclipse中工作正常。 但是，当我把Java文件导出到一个Runnable jar文件时，我得到一个错误（堆栈跟踪在这篇文章的底部）。 谁能帮我解决这个问题吗？
请在下面find我的Java代码：

我觉得这个问题正在发生，而将数据写入Excel /从Excel中读取数据。 你可以请build议任何解决scheme？
我已经以正确的方式将java代码导出到jar文件。 我已经通过导出另一个示例程序来证实这一点，并且它完美地工作。 此问题只发生在涉及Excel读取和Excel写入操作的程序中
我认为这是你的问题：
Caused by: Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named sikuli****
它似乎无法导入sikuli。
