Useful pre-commit hook for linting Java code. It uses as default [The Google Style Guide](https://google.github.io/styleguide/javaguide.html)

It uses the famous [Checkstyle](http://checkstyle.sourceforge.net/) linter as a plugin for [pre-commit](https://github.com/jish/pre-commit).

## Demo

![My awesome change has been catch. Oh boy!](https://raw.githubusercontent.com/CristianOliveiraDaRosa/java-checkstyle/master/readmedemo.png)

## Installation

First install the gems.
### Pre-Commit Checkstyle

    gem install pre-commit

### Java Checkstyle Plugin

    gem install java-checkstyle

### Configuring
Use the pre-commit command to generate a stub pre-commit hook.
Inside folder of your git repo:

```bash
pre-commit install
```

It will create a .git/hooks/pre-commit script which will check your git config and run checks that are enabled.

### Enabling checks

``` bash
pre-commit enable git checks checkstyle
```

OR

``` bash
pre-commit enable yaml checks checkstyle
```

### Result
Every time you try to commit some java code with style errors it will validate
before.

## Installing with RVM

If you are using rvm you need to install pre-commit into the ```default``` gemset, because it does not use the ```current``` environment

    $ rvm default do gem install pre-commit

Alternatively you can configure pre-commit to use the ```current``` rvm gemset

    $ git config pre-commit.ruby "rvm `rvm current` do ruby"

More details about this part see on:
[pre-commit](https://github.com/jish/pre-commit)

And your pre-commit hook has been configured.

## Checkstyle Guide

It uses as default [The Google Style Guide](https://google.github.io/styleguide/javaguide.html).
