私はvaadin 7.0.0のサンプルアプリケーションをEclipse用のmavenプラグインでパッケージ化しようとしていますが、目標「パッケージ」を実行するたびに、ビルドは次のエラーで失敗します。

私はmavenを使い始めたばかりです。このエラーに関する投稿をたくさん見つけても、このエラーの原因を理解できていません。
ここに問題があるようです:
[致命的]解析不可能なPOM C:\ Users\Benoit.m2\repository\org\Apache\maven\maven-parent\16\maven-parent-16.pom
このエラーのため、Mavenは必要なすべてのライブラリをプラグインのクラスパスに追加できませんでした。
C:\Users\Benoit\.m2\repository\org\Apache\maven\
のすべてを削除して、プロジェクトを再構築することをお勧めします。これは役立つはずです。
