this や this ;のような投稿はすでに見ました。すべての.m2フォルダーを削除し、pom内のソースを変更して、URLとして報告されたすべてのjarがリポジトリに存在するかどうかを確認しようとしました(すべてがそこにありました)。
ありがとうございました

最善の方法は、ディスクを完全にクリーンアップし、 ここ から最後のバージョン(3.5.3)をインストールすることです。確かに、システムウィンドウから環境変数を削除して、再度作成してください。
システムにインストールされているApache Mavenバージョン:.5.(mvn -vの結果)pom.xmlのmaven-compiler-plugin.8.のバージョンよりも低い
Eclipseでは、AntJava.home変数はWindowsJava_HOME環境変数に基づいていません。代わりに、プロジェクトのJREのホームディレクトリに設定されます。
デフォルトのJREを変更するには(たとえば、JDKに変更する)、[Windows]-> [設定...]に移動し、[Java]-> [インストール済みJRE]を選択します。-> [編集]-> C:\ Program Files\Java\jdk1 .8.0_172
私はIntellij Ideaを使用し、プロジェクトを再構築することで解決しました
