Почему я получаю предупреждение «с разделенным пакетом»?

Question

Я строю .kar-файл, но когда я бегу mvn package я получаю эту ошибку:

Я просто не могу понять что вызывает эти ошибки. Когда я читаю пакет split, я получаю очень полезный совет, который следует избегать сплит-пакета. Да ... Я не контролирую, что такое когда-либо за jaxb-impl, jaxb-core или com/sun/*.

Любые идеи по устранению неполадок?

Answer 1

Значение по умолчанию для экспорта-пакета является {local-packages} и не *

С директивой Export-Package: *, вы просите BND экспортировать все зависимости вашего проекта.

Снимите * или использовать {local-packages}

Редактировать:

Обратите внимание, что вы должны только экспорт общественного API из Bundle. Все остальное должно быть конфиденциальным. По умолчанию maven-bundle-plugin экспортирует все пакеты, кроме пакета, содержащего impl или internal. Если вы можете, вы должны придерживаться этого соглашения и опустить директиву Export-Package или явно экспортировать свои общедоступные пакеты.
