java - Maven: mvn パッケージの失敗

Question

「mvn package」コマンドを使用して、maven プロジェクトから実行可能な .jar ファイルを作成しようとしています。しばらくは機能していましたが、デバッグモードでコマンドを実行した後、次のようになりました。

実際のコード以外は何も変更していないため、どこでエラーを探すべきかわかりません。端末から問題なく実行できるため、これとは関係がないようです。pom.xml ファイルの何らかの設定か何かだと思いますが、何を探しているのかわからないまま、そこにあるものを変更したくありません。どんな助けでも大歓迎です、ありがとう。

それが役立つことを願って、ここに私のpom.xmlがあります：
