java - Java 搜索中的类文件名必须以 .class 异常结尾

Question

我希望有人可以帮助我解决在特定项目中使用 Eclipse 中的 java 搜索功能时遇到的问题。

在一个特定项目上使用 java 搜索时，我收到一条错误消息，提示 Class 文件名必须以 .class 结尾(请参阅下面的堆栈跟踪)。似乎并非所有项目都发生这种情况，只是一个特定的项目，所以也许我应该尝试重建一些东西？

我已经尝试过Project -> Clean... 和Closing Eclipse，删除所有构建的类文件并重新启动Eclipse 无济于事。

我在 Google 上找到的关于该问题的唯一引用资料是 http://www.crazysquirrel.com/computing/java/eclipse/error-during-java-search.jspx ，但不幸的是他的解决方案(关闭、删除类文件、重新启动)对我不起作用。

如果有人可以提出一些尝试的建议，或者我可以收集更多信息来帮助追踪它，我将非常感谢您的指点。

Version: 3.4.0
Build id: I20080617-2000

也刚刚找到这个帖子 - http://www.myeclipseide.com/PNphpBB2-viewtopic-t-20067.html - 这表示当项目名称包含句点时可能会出现同样的问题。不幸的是，我的设置不是这样，所以我仍然卡住了。

感谢 McDowell，关闭和打开项目似乎已经修复了它(至少现在是这样)。

评论#9 to bug 269820解释如何删除搜索索引，这似乎是解决索引损坏的方法，其症状是可怕的

An internal error occurred during: "Items filtering".
Class file name must end with .class

消息框。

如何删除搜索索引:

1. 关闭 Eclipse
2. 删除 /.metadata/.plugins/org.eclipse.jdt.core/*.index
3. 删除 /.metadata/.plugins/org.eclipse.jdt.core/savedIndexNames.txt
4. 再次启动 Eclipse
