我正在学习Eclipse中的插件开发，并决定按照Vogella上的教程（http://www.vogella.com/tutorials/EclipsePlugIn/article.html#top）但是，一旦我右键单击项目并选择'，我的控制台就会出现错误作为eclipse应用程序运行'（教程中的4.2）。
这是错误：

I'm not sure if this is to do with my configuration/workspace settings. Any help would be much appreciated.
答案 0 :(得分：1)
从您的错误开始：
java.io.FileNotFoundException: /icons/sample.gif
您的插件无法找到图标目录或sample.gif文件。
确保您的图标目录位于插件类路径中。
答案 1 :(得分：0)
该异常的问题在于您的插件已部署，并且正在查找无法找到的引用路径中的资源。 尝试创建一个图像，并根据该类的路径设置图标的路径......
这样的事情：new Image(yourDisplay, getClass().getClassLoader().getResourceAsStream("icons/your-icon.png"))
这应该可以正常工作！
