java - 配置jnotify和libnotify.so时java路径错误

Question

我使用一些 swing 组件开发了一个应用程序，该应用程序使用 jnotify 来监视文件夹，它在 eclipse 中工作正常，但是当我生成 jar 文件并尝试在我的系统上执行该 jar 时，它显示以下错误，我尝试了很多方法来解决此错误 但它仍然给我同样的错误，请告诉我做错了什么。

$$ java -jar DemoJFileChooser.jar

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，只是 jar 的大小现在是以前的 jar 文件的 15 倍。
