### ソースコードの取得

1. Fessのリポジトリをクローンします：
    ```
    $ cd ~/workspace
    $ git clone https://github.com/codelibs/fess.git
    ```
    
2. クローンしたリポジトリを、[Maven](https://maven.apache.org/)プロジェクトとして[Eclipse](https://www.eclipse.org/eclipseide/)や他のIDEにインポートします。

### OpenSearchプラグインのセットアップ

antrun:runを実行して、プラグインをpluginsディレクトリにダウンロードします：

    $ mvn antrun:run
