macにgradleをインストールする

Macにgradleをインストールするための個人的な備忘録。
毎回忘れてjarをインストールするのって大変だなぁと思ってしまうので。

# updateをかける
<pre>
$ brew update
</pre>

なんかエラーでるので、書かれたとおりにuntapしていく
<pre>
$ brew untap homebrew/homebrew-dupes
$ brew untap homebrew/homebrew-x11
</pre>

# gradleをインストール
<pre>
$ brew install gradle
</pre>

# ついでにメンテナンス
<pre>
$ brew cleanup
</pre>

# 目的のディレクトリまで移動
build.gradleなどが入っているディレクトリまで移動

# 初期処理
<pre>
$ gradle
</pre>
こんなのがでる
