(item)不在项目构建路径上

Question

我反编译了一个jar,将文件导入eclipse,并编辑了一些关键的java文件.每当我尝试出口时,它给了我一个

"JAR creation failed. See details for additional information. UHC-2.4.1/META-INF/MANIFEST.MF was replaced by the generated MANIFEST.MF and is no longer in the JAR. uk/co/eluinhost/UltraHardcore/features/core [in UHC-2.4.1] is not on its project's build path Unable to get package fragment root: UHC-2.4.1/uk/co/eluinhost/UltraHardcore/features/core/GoldenHeads.java uk/co/eluinhost/UltraHardcore/features/core [in UHC-2.4.1] is not on its project's build path" error. 

我已经远远地搜索了一个解决方案,但是还没找到.我尝试刷新项目等,并指定了所有必需的库.请帮忙？附加信息:如果我编辑任何其他类(只需添加一个空格然后删除它然后保存)该类也会添加到错误消息中.

我遇到过同样的问题.我注意到所有列在"不在项目构建路径上"的文件都在Eclipse中打开进行编辑.一旦我关闭了所有打开的文件,我就可以导出jar了.

我认为他们被锁定进行编辑,因此无法导出.
