Я создал проект Grails 3.1.0 с 5 классами доменов, 3 домена — это пользователь, роль и роль пользователя из Spring Security Plugin, а остальные 2 находятся в отношениях 1 ко многим.
Я подключаюсь к MySQL 5.6, и мой dbCreate настроен на обновление.
При запуске проекта с чистой базой данных таблицы создаются, и все хорошо, но когда я запускаю проект с использованием базы данных с уже созданными таблицами, запуск завершается с ошибкой NullPointerException.
Мне нужно удалять и создавать базу данных каждый раз, когда я запускаю свое приложение.
Трассировка стека:
ERROR grails.boot.GrailsApp - Application startup failed
java.lang.NullPointerException: null
