pom.xml がminify-maven-pluginを利用するプロジェクトがあります。$M2_HOME/conf/settings.xml で pluginRepository エントリを構成する方法に関するドキュメントが見つからなかったので、勝手な推測をして、次のエントリを追加しました。
<pluginRepository>
<id>minify-maven-plugin-repo</id>
<name>minify-maven-plugin repository</name>
<url>https://github.com/samaxes/minify-maven-plugin</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
しかしmvn minify:minify、プロジェクト ディレクトリから実行すると、次のようになります。

私は何を間違えていますか？
私は Maven 2.2 を使用しています。minify-maven-plugin は github にあるため、必要に応じて egit プラグインを追加しました。
