Eclipse: Unable to build the project
提问by Anshuman Sharma
The project was not built due to "Resource already exists on disk: ''.". Fix the problem, then try refreshing this project and building it since it may be inconsistent
由于“磁盘上已存在资源：''。”，该项目未构建。解决问题，然后尝试刷新此项目并构建它，因为它可能不一致
I am getting above error whenever I am trying to build the project. Earlier the project was running fine, but all of sudden it stopped running and giving this error.
每当我尝试构建项目时，我都会遇到上述错误。早些时候该项目运行良好，但突然间它停止运行并出现此错误。

Project right click --> Build Path --> Configure Build Path and you have seen Project source paths.And attention please,
项目右键--> 构建路径--> 配置构建路径，你已经看到了项目源路径。请注意，
If you have more than one source, you should probably encountered this problem. You should examine each source.
如果您有多个来源，您可能会遇到这个问题。您应该检查每个来源。
Source click --> edit --> next --> and you seen exclusion patterns and inclusion patterns.
源单击--> 编辑--> 下一个--> 您会看到排除模式和包含模式。
For example, your directory path
例如，您的目录路径
source

\------ExDir

\------IncDir
You must select for inclusion only IncDir and select for Exclusion only ExcDir
您必须选择仅包含 IncDir 并选择仅排除 ExcDir
- If you select for exclusion source Directory you encounter this problem.
- 如果您选择排除源目录，则会遇到此问题。
