Fix indentation & no-missing-end-of-source-newline

Reported by codacy, though i send you a pull for this small fix.
The empty line on 31 is supposed to fix the no-missing-end-of-source-newline warning.

Sadly can't help with the java stuff, tho the issues/warnings seem to be consitent.

Also, would you like to have your workflow changed to automatically make a new release?
