推荐答案

不知道你是否满意地解决了这个问题，但我今天在使用 Eclipse 3.6 中的一些 Spring 配置文件时遇到了这个帖子.无论如何，我都无法让错误在 Eclipse 的问题"视图中消失，直到我右键单击该问题并将其删除.

Not sure if you ever resolved this satisfactorily but I ran across this posting today while working with some Spring configuration files in Eclipse 3.6. I could not get the error to go away in the Problems view in Eclipse no matter what, until I right-clicked on the problem and deleted it.

我认为如果我重新验证并且确实存在问题，它会回来，但到目前为止还没有.问题是我有一个几乎相同的 Spring 配置文件，但没有显示错误.

I figured it would come back if I revalidated and there was actually a problem and so far it hasn't. The thing is I had an almost identical Spring config file that wasn't showing the error.

似乎有时某些东西会卡在 Eclipse 中.不知道为什么，但是在这与文件与编辑器不同步并且不得不强制刷新之间，我想我必须接受它.

It would seem that sometimes stuff just gets stuck in Eclipse. Not sure why but between this and files getting out of sync with the editors and having to force a refresh I guess I have to accept it.
