git commit时出现的问题The file will have its original line endings in your working directory

我最近使用了新的代码托管工具，把之前在oschina上的代码迁移到coding.net上去。提交代码时有一个文件提交失败。
错误信息是
LF will be replaced by CRLF in git -the file will have its original line endings,The file will have its original line endings in your working directory.

查资料发现这是windows和mac系统的换行符不同导致的问题。windows使用CRLF 也就是回车换行，而mac使用LF单个换行。git默认支持LF。windows commit代码时git会把CRLF转LF，update代码时LF换CRLF。所以windows会有默认 core.autocrlf true 。Mac 用户commit,update都用LF 所以 core.autocrlf input。

废话少说，怎么commit代码？
简单，把报错的文件删了重新建相同文件粘贴代码就ok了
