Я нашел несколько похожих сообщений с mvn, но ни одного с Gradle.Вот проблема.
Я захожу в Файл-> Структура проекта-> Проект и меняю Project SDK на 11, а Уровень проекта на 10. Я нажимаю «Применить», ошибки исчезают.
Я обновляюGradle Project, выберите Файл-> Структура проекта-> Проект и его Project SDK установлен на 8 и Project Language Level на 6.
Итак, после прочтения проблем, которые я обнаружил здесь в stackoverflow, вот мой build.gradle.
