Каким будет groupId для зависимостей, используемых внутри pom, если в свойствах не указана переменная?

Question

Пом, что я смотрю в это:

Я не могу понять, что именно groupId будет использоваться везде, где $ {pom.groupId} указан в используемых зависимостях. Я посмотрел в родительском pom и не смог найти там никаких переменных, определенных с именем pom.groupId. Так откуда будет взята группа?

Единственное предположение, которое я могу сделать, это то, что он должен использовать groupId самого pom, но его там тоже нет, присутствуют только теги artifactId и version.
Примечание. Я получаю pom с помощью информации GAV, поэтому у меня есть groupId, но я уверен, что должен быть более конкретный или какой-то другой способ определения groupId из самого pom.

Еще один экземпляр pom, где это было сделано (3-я зависимость), но здесь присутствует тег groupId, но нет $ {version}:
Каковы будут значения $ {groupId} и $ {version} здесь? (У родителей этого помета тоже нет переменных с таким именем)
