これは興味深い問題であり、私が何か間違ったことをしているのか、それとも Maven の制限なのかはわかりません。
このシナリオの最も単純なバージョンは、親 POM、単一の子 POM、および集約 POM があるというものです。アグリゲーション POM は、単にモジュールを連結するためのものです。
アグリゲーション POM をインストールすると、親 POM に対する子 POM の依存関係が検出されません。私は相対パスを持たないことを好み、Maven アーティファクトの理解から可能になるはずです。
どんな洞察も大歓迎です。ありがとう。
これは超親です (何も入っていないことを気にしないでください)
