background
Under each operating system, the newline characters used in text files are different. UNIX/Linux uses 0x0A(LF), early Mac OS uses 0x0D(CR), and later OS X is consistent with UNIX after changing the kernel. But DOS/Windows has always used 0x0D0A(CRLF) for newlines. Git provides a "newline automatic conversion" feature. This feature is in "auto mode" by default, when you are checking out a file, it tries to replace UNIX newlines (LF) with Windows newlines (CRLF); when you commit files, it tries to replace CRLF with LF. Git's "automatic newline conversion" feature sounds smart and sweet, as it tries to keep files in the repository consistent (UNIX-style) and compatible with local files (Windows-style). Unfortunately, this feature is buggy and unlikely to be fixed anytime soon.
In eclipse, set the newline character of Unix for newly opened files

There is also a problem with newlines when using git in Windows
solve
1.Git settings:
git config --global core.autocrlf false
git config --global core.safecrlf true
Meaning:
AutoCRLF #Convert
to LF when submitting, and convert to CRLF when checking out
git config --global core.autocrlf true
#Submit Convert to LF when checking out, not convert when checking out
git config --global core.autocrlf input #Do
not convert
git config --global core.autocrlf false
SafeCRLF #Refuse
to submit files containing mixed newlines
git config --global core.safecrlf true #Allow
submission of files containing mixed newlines
git config --global core.safecrlf false #Give
a warning when submitting files containing mixed newlines
git config --global core.safecrlf warn
