gradle: проблемы с папкой OSGI-INF для плагинов OSGI/SCR

Когда я пытаюсь сгенерировать OSGI-пакет с информацией о папке OSGI-INF, я не могу создать эту папку с помощью apply plugin: 'scr' в моем файле сборки gradle. Любые указатели, пожалуйста?

Я использую Java 1.8.Task, где он терпит неудачу, это task ':processScrAnnotations'.

Я получаю следующее исключение, которое не дает полезных сообщений:
