Same change keeps reappearing after checkout

Question

Git keeps adding the same changeset, which looks like this:

@@ -1,12 +1,12 @@
-<?xml version="1.0" encoding="utf-8"?>
-<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

 </LinearLayout>
\ No newline at end of file

The file is not open in any editor, and every time I discard changes by doing a git checkoutor by using the github tool, the changes reappear without me even doing anything. Committing the files changes nothing, the same changeset reappears immediately.

How do I keep it from doing this?

Answer 1

Whole file is always changed? Line endings! (read it as LINE ENDINGS!!!)

You can read git's manual on line ending conversion, Github also as a nice detailed explanation on this, but to put it basically:

• Your editor should use expected line endings (most people stick with the OS default)
• Your core.autocrlf in gitconfig should follow the editor's option.

You might need to issue a commit fixing the line issue if you made a commit with the wrong line ending (i.e. the git repo should always be in LF).
