【问题描述】：
目前我分发的其他人从 java 运行时环境中获取“发生 Java 异常”。我将如何将其作为 .jar 正确分发？

【问题讨论】：
-
你有堆栈跟踪吗？将其添加到您的问题中。
-
This:
catch(IOException e){};是您可以在 Java 程序中放置的最糟糕的东西之一。严重地。始终处理您的异常。总是。 -
您的 GUI 将图像文件作为文件从硬编码文件路径访问，我确信您朋友的计算机没有相同的路径。不要这样做，而是将您的图像与您的 jar 文件打包并作为资源而不是文件访问它们。如果你搜索这个网站，你会发现如何做到这一点。再次，处理您的异常，因为这可能会使您和您的朋友对错误的实际来源视而不见。你的空catch块不是送给你的朋友的好东西。

@Hovercraft Full Of Eels - 非常好。但是，使用 cmets 回答问题对 OP 以外的任何人都没有多大帮助。
-
@StuPointerException：我开始写答案，但我在工作，没有时间写我认为足够的答案，恐怕包括资源的处理和放置.如果您有时间，我将不胜感激。
