类文件名必须以 Java 搜索中的.class例外结尾
我希望有人能帮助我解决我在特定项目上使用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（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？Class file name must end with .class
我已经试过了...和关闭 Eclipse，删除所有构建的类文件并重新启动 Eclipse，但无济于事。Project -> Clean
我在Google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，或者我可以收集到任何可能有助于跟踪它的信息，我将不胜感激。

也刚刚发现这个线程 - 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，在我的设置中情况并非如此，所以我仍然卡住了。

感谢McDowell，关闭和打开该项目似乎已经修复了它（至少现在是这样）。
