Сколько раз Maven должен загружать метаданные в одной сборке?

Question

Допустим, у меня есть проект Maven, который:

• является многомодульным проектом (также является родителем его модулей, что является обычным и предполагается, что некоторые плагины функционируют правильно),
• использует (gitflow-incremental-builder расширение) строить только модули, которые были изменены и их зависимых, и
• использует nexus-staging-plugin расширение для развертывания артефактов в хранилище Nexus в конце успешной сборки (то есть, только если все модули, которые мы собираем, успешно выполняются).

В течение некоторого времени каждое расширение работало, как и ожидалось, во множестве сборок, т. Е. Строятся только измененные проекты и их зависимые объекты (другие пропускаются), а созданные артефакты развертываются в Nexus после того, как все проекты успешно построены (т.е. нет артефактов). развернута, если что-нибудь не получится). Но на днях я заметил:

Я подозреваю, что проблема в конфликте между двумя расширениями как-то? Как мы можем определить, по крайней мере, если проблема связана с одним расширением, а не с другим, если комбинация этих двух причин является причиной вышеуказанного поведения?
