• 5行目がミソ。今のところ webapp アーキタイプでは、Javaのソース格納フォルダが生成されない
• 8行目の-DdownloadSources?=trueは、現時点での依存ライブラリのJavaソースコードを取得して、Eclipseから参照できるようにするオプション

WTPへのインポート †

1. Eclipse上で資産のインポートを選択します
   
2. 既存のプロジェクト（さっき作ったMavenプロジェクト)をインポートします
   
3. 適当に選んで終了
   
4. インポート直後はコンパイルエラーが出てきます
   
5. Maven2プラグインを有効化します
   
6. [Source Folder Update]を選択します。（コンパイルエラーを消すためのおまじない）
   
7. コンパイルエラーが消えました
   

Warファイルの作成(Mavenの実行) †

1. 外部ツールを選択します
   
2. 新しいMavenプロジェクトを作成します。goal は、とりあえず package (warファイルの作成)
   
3. 「実行」ボタンを押すと、Maven が実行されました.
   

開発環境(WTP-JBOSS)内での実行 †

1. プロジェクトを右クリックして、[実行]-[Run on Server] を選択します
   
2. JBOSSサーバを選択し
   
3. warファイルを追加します
   
4. [終了]を押すと、warファイルがdeploy(配備)されて実行されます
