类文件名必须以Java搜索中的.class异常结尾

Question

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启Eclipse无济于事.

我在谷歌上找到的唯一一个问题是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.

如果有人可以提出尝试的建议,或者我可以收集任何可能有助于跟踪它的信息,我会非常感谢指针.

Build id: I20080617-2000

还发现了这个帖子 - 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,在我的设置中并非如此,所以我仍然卡住了.

感谢McDowell,关闭并打开项目似乎已经解决了这个问题(至少目前为止).

Answer 1

错误269820的评论#9解释了如何删除搜索索引,这似乎是腐败索引的解决方案,其症状是可怕的

在"项目过滤"期间发生内部错误.
类文件名必须以.class结尾

消息框.

如何删除搜索索引:

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

Answer 2

另外两个用于修复Eclipse某些特性的通用机制:

• 关闭并打开该项目
• 删除项目(但不是从磁盘!)并将其重新导入为现有项目

如果做不到这一点,bugs.eclipse.org可能会提供答案.

如果工作空间缓存了某些内容,您可以通过在workspace/.metadata/.plugins中进行浏览来删除它.大部分内容都是相当短暂的(虽然备份和观察已删除的首选项).

Answer 3

前几天得到了这个错误.尝试手动删除输出文件夹中的所有.class文件和资源.没工作.重新启动我的电脑(WinXP).没工作.在Eclipse中关闭我的项目并再次打开它.工作!希望这解决了那里的某些问题.搜索工具对Eclipse来说至关重要.

Answer 4

我最近也遇到过这个问题,下面的场景对我有用.

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