Today spotbugs forces *nix line endings on files. This ignores windows users. As a result, many files were so messed up on windows for me at least that I had to run spotless constantly to get a build to work. If I use notepad for example to open files like these, they are not readable. So we need to respect windows users properly. Let git checkout as suggested instead of being heavy handled mac / unix so we get more broad support from contributors.
