У меня есть приложение Spring Boot (2.2.5), которое зависит от плагина Grails (4.0.1), который содержит объектные модели домена, совместно используемые несколькими проектами.
Все запускается и работает хорошо (I может запрашивать базу данных из SB, используя Dynami c finders), когда я начинаю использовать bootRun из Gradle, но когда я пытаюсь запустить IntelliJ (2019.1.3), используя конфигурацию запуска Spring Boot, выдается исключение ниже.

Не конец света, но IntelliJ предоставляет некоторые приятные возможности при запуске приложения Spring Boot с помощью встроенного инструмента.
