[解決済み】Maven 依存関係を解決できず、アーティファクトを解決できなかった

質問

これは私の友人からの作業プロジェクトのはずです。 彼は私の目の前でプロジェクトを実演し、私はそのプロジェクトをコピーし、既存のMavenプロジェクトとしてインポートしました（私は m2eclipse プラグインを使用します)。

そして、このエラーが発生します。このエラーは、私がmavenで何かをビルドしようとするたびに再現されます。

mvn dependency:tree、dependency:list、あるいは通常のビルドパッケージを実行しても、同じエラーになります。

eclipseから'package'ビルドを実行したときのエラーは。

mavenの最新版をダウンロードし、eclipse heliosに含めてみましたが、やはり同じ問題です。シェルのコマンドライン（eclipseの外側）で実行しても、同じエラーメッセージが発生します。

何が足りないのでしょうか？

解決方法は？

Mavenのレポが不足しているようです。お友達の .m2/settings.xml そして、おそらくそこにリポジトリを含めるためにPOMを更新したいと思うでしょう。

--edit: ちょっとググってみたところ、これをPOMに追加してみてください。
