我希望有人可以帮助我解决我在特定项目中使用 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Class file name must end with .class（请参阅下面的堆栈跟踪）。这似乎并没有发生在所有项目上，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......并关闭 Eclipse，删除所有构建的类文件并重新启动 Eclipse 无济于事。
我在谷歌上找到的唯一参考是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。
如果有人可以建议尝试一些东西，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
也刚刚找到这个线程 - http://www.myeclipseide.com/PNphpBB2-viewtopic-t-20067.html - 这表明当项目名称包含句点时可能会出现同样的问题。不幸的是，我的设置并非如此，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）。
