Spring boot repackage: задача Jar не переупакована (не соответствует JarTask)

У меня есть новый проект Grails 3.1.7, скомпилированный оболочкой gradle. Проект - это просто базовый проект, созданный: grails create-app

Когда я запускаю: ./gradlew --info clean jar bootRepackage

Я вижу следующий вывод во время последней части сборки

:jar (Thread[main,5,main]) started.
:jar
