A handy pre-commit hook which will run Google's java code style formatter for you on your code!

Usage:

repos:
-   repo: https://github.com/Allen-HiCharlie/google-style-precommit-hook.git
    sha: be756657f2f7e3882e43ce005746dfa8c949a671
    hooks:
    -   id: google-style-java

Note: this file stores Google's code style formatter jar in a .cache/ directory so that it doesn't need to be re-downloaded each time. You will probably want to add .cache/ to the .gitignore file of the project which uses this hook.
