Некоторое время назад у меня была похожая проблема, вы можете избежать замены Maven для свойств, разрешения путей и т. Д., Определив новый плагин Maven для следующих действий.
- Разрешить каждого родителя, используя стандартную фабрику артефактов
- Чтение каждого файла pom (без разрешения) с помощью MavenXpp3Reader
- Слияние нерешенных проектов
- Запишите объединенный проект в файл
Вот некоторый тестовый код, который я использовал, чтобы доказать этот процесс для себя, вам, очевидно, нужно обернуть это в плагин Maven и связать его с какой-то фазой вашего процесса. Разрешенный pom выводится в выходной каталог (т. Е. Target) с именем resolved-pom.xml по умолчанию, эти два свойства можно переопределить с помощью обычного подхода к настройке подключаемого модуля Maven, установив свойства outputDir и / или pomfileName. .
