Currently developers need to run:

{format}

python ./buildscripts/download_buildifier.py && python ./buildscripts/buildifier.py fix-all
{format}

Update buildifier.py to call download_buildifier.py if a buildifier binary is not present so developers just need to invoke one script.

 

Bonus: If possible try to create a helper script to invoke all quick-running formatters so developers don't have to run a bunch of scripts
