标签： java linux jnotify

我开发了一个使用一些swing组件的应用程序，应用程序正在使用jnotify来监视文件夹，它在eclipse中运行正常但是当我生成jar文件并尝试在我的系统上执行该jar时它向我显示以下错误，我在解决这个错误方面做了很多努力 但它仍然给我同样的错误，请告诉我我做错了什么。

我使用Fat Jar Eclipse插件http://fjep.sourceforge.net/及其教程http://fjep.sourceforge.net/fjeptutorial.html然后我使用eclipse的导出选项并选择Runnable JAR文件，现在它工作正常，除了jar的大小现在以前的jar文件的15倍。
