在Eclipse中覆盖注释的Bug [英] Bug with Override annotations in Eclipse
问题描述
我在Eclipse中的 @Override 注释中有一个令人讨厌的问题。通常，当我在一台新的电脑上导入工作项目时，Eclipse将某些 @Override 注释标记为错误。如果我删除注释，一切都很好，Eclipse也表示方法覆盖了父方法，但是添加覆盖注释会再次导致错误。我目前正在研究一个Android项目，所以这可能是Android的问题，而不是Eclipse。
I have a annoying problem with @Override annotations in Eclipse. Often when i import working projects on a new PC, Eclipse marks some of the @Override annotations as wrong. If i remove the annotations everything is fine and Eclipse also indicates that the methods are overriding the parents methods but adding the Override annotation causes the error again. I am currently working on an Android project so it might be a problem with Android and not with Eclipse..
推荐答案
这是最多的可能是因为您在Java 1.5和Java 1.6之间进行切换。在1.5中，您无法使用@Override标记接口实现，但可以在1.6中。
This is most likely because you are switching between Java 1.5 and Java 1.6. In 1.5 you couldn't mark interface implementations with @Override, but you can in 1.6.
一个快速的Google搜索可以很好地解释这个注释之间的区别两个版本： http://www.techienuggets.com/CommentDetail?tx=38155

JDK 1.5和JDK 1.6中的@Override的语义不同。在JDK 1.5中，不允许
@Override注释
用于在接口中声明的方法
的实现，而在JDK 1.6中允许
。有关更多
信息，请参阅：
Semantics of @Override is different in JDK 1.5 and JDK 1.6. In JDK 1.5, the @Override annotation is not allowed for implementations of methods declared in an interface, while they are allowed in JDK 1.6. For more information, see:

事实上，JDK API文档中
覆盖注释的描述未更新
。这是
报告为一个错误：
It is fact that the description of the Override annotation was not updated in the JDK API docs. This has been reported as a bug:
