Mavenお仕着せのディレクトリ構成を受け入れることにより、
コマンド一発でコンパイル・テスト・Jar作成などができる。
すばらしい！

インストール †

  1. Javaがインストールされており、環境変数JAVA_HOMEが設定されているのが前提
  2. http://maven.apache.org/ より、maven-2.0.4-bin.zip を取得
  3. 適当なところに展開 (ここでは C:\Maven2 )
  4. パスを通す 
    コントロールパネル > システム > システムのプロパティ
 > 詳細設定タブ > 環境変数ボタン
    path.png
     
    MAVEN_HOMEC:\Maven2
    PATH…(既存)…;%MAVEN_HOME%\bin
  5. インストールできたか確認 
    C:\>mvn --version
Maven version: 2.0.4
