Solution 4 - Intellij Idea

Possible alternative with a number of handy features is EditorConfig

Just submit an .editorconfig file to your repo

[*]
insert_final_newline = true

And it will work natively not only in Idea, but in all major IDEs (some require a plugin).

Now all team members would have same configuration, eol, eof, and no more tabs vs spaces :)

Solution 7 - Intellij Idea

In latest versions of IntelliJ, the setting has been renamed to 'Ensure an empty line at the end of a file on save', and it has been moved under Setting>Editor>General>Save Files

This should have been a comment, but I wanted to add the screenshot as well so wrote as an answer.

Solution 8 - Intellij Idea

As Rider (IDEA's cousin for .NET) is driving me crazy, this might be helpful for those writing C# as Ensure line feed at file end on Save alone won't work. It needs

File → Settings → Editor → Code Style → C# → Line Breaks and Wrapping → Line feed at end of file.

I don't remember changing it and I haven't imported any settings for sure, so I guess it's by default disabled.

And then select/deselect "Ensure every saved file ends with a line break"
