Ошибка разработки подключаемого модуля

Question

Я изучаю разработку плагинов в Eclipse и решил следовать инструкциям по Vogella (http://www.vogella.com/tutorials/EclipsePlugIn/article.html#top) Однако, я получаю сообщение об ошибке на моей консоли, как только я нажимаю правой кнопкой мыши на проекте и выбираю «запускается как приложение eclipse» (4.2 в учебнике).

Здесь ошибка:

Когда я удалить значок = "Значки/sample.gif" от build.properties, я получаю следующее сообщение об ошибке:

I'm not sure if this is to do with my configuration/workspace settings. Any help would be much appreciated. 

Answer 1

прямо с ошибкой :

java.io.FileNotFoundException: /icons/sample.gif 

Ваш плагин не может найти каталог значков или файл sample.gif.

Убедитесь, что ваш каталог значков находится в плагине класса плагина.

Answer 2

Проблема с этим исключением заключается в том, что ваш подключаемый модуль развернут и ищет ресурсы по указанному пути, которые не могут быть найдены. попробовать что-то вроде создания образа и установить путь к пиктограммам по пути этого класса ...

Что-то вроде этого: new Image(yourDisplay, getClass().getClassLoader().getResourceAsStream("icons/your-icon.png"))

и это должно работать нормально!
