Я использую JHipster 5.8.1 на Manjaro Linux Intel i7 (x64), и у меня возникла проблема с моим приложением Jhipster.То есть я создал проект, правильно импортировал свои jdl-сущности и настроил приложение в файле application-dev.yml, но при запуске mvn spring-boot:run JHipster печатает несколько строк журнала, и программа застревает в одной из них и долго зависаетвремя в строке

Возможная причина: mysql отказывается от соединений по неизвестной причине.Я ожидаю, что Jhipster запустит приложение и покажет ссылки для доступа к приложению, работающему как на бэкэнде, так и на фронтенде.
Спасибо за помощь!
