플러그인 개발 오류

Question

Eclipse에서 플러그인 개발을 배우고 있으며 Vogella (http://www.vogella.com/tutorials/EclipsePlugIn/article.html#top)의 자습서를 따르기로 결정했습니다. 프로젝트를 마우스 오른쪽 단추로 클릭하자마자 콘솔에 오류가 발생합니다. 'eclipse 애플리케이션으로 실행'(튜토리얼에서 4.2). 여기

오류입니다 :

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

Answer 1

마우스 오른쪽 버튼을 :

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

플러그인이 아이콘 디렉토리 또는 sample.gif 파일을 찾을 수 없습니다.

아이콘 디렉토리가 플러그인 클래스 경로에 있는지 확인하십시오.

Answer 2

해당 예외의 문제점은 플러그인이 배치되어 있으며 참조 된 경로에서 찾을 수없는 자원을 찾고 있다는 것입니다. 이미지를 만드는 식으로 뭔가를 시도하고 그 클래스의 경로에 따라 아이콘의 경로를 설정 ...

뭔가 같이 : new Image(yourDisplay, getClass().getClassLoader().getResourceAsStream("icons/your-icon.png"))

및이 잘 작동합니다!
