How do I make IntelliJ IDEA insert a new line at every end of file, so that GitHub doesn't complain for example?
回答1:
Change your Editor settings:
Settings → Editor → General → Ensure line feed at file end on Save
回答2:
For MAC users:
Preferences > Editor > General > Ensure line feed at file end on save
回答3:
IntelliJ IDEA 2016.3
Approach 1
File > Settings... > Editor > General > Ensure line feed at file end on Save
Approach 2
Help > Find Action... (Ctrl+Shift+A) > type "Ensure line feed" > switch the toggle to ON (using the mouse click or Enter) for "Other: Ensure line feed at file end on Save" line

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 :)

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.

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.
