Возможные проблемы с proguard

Сегодня решил сделать релизную версию. Оказалось, что proguard что-то режет. Сразу скажу, что ни один из потерянных классов мне не знаком, да и код я с последнего релиза не сильно менял, а ведь тогда он работал! Подскажите, что добавить в proguard, чтобы этот зверь снова заработал?
Ниже привожу exception потерянных классов:

Вот такая вот простыня... Попробовал добавить костыльный hotfix:
-keepclassmembers class ** { *; }
но это не помогло. Кто сталкивался с подобной проблемой? Как ее можно быстро решить?

Ответ

Проблема оказалась в следующем: один из разработчиков заиспользовал для своей версии reflections из java, которая была подключена с помощью maven. Он использовал ее в своем productFlavors, но подключил в общий gradle файл. В общем удалив это безобразие, мы получили рабочую сборку! Если что, такую ошибку вызывает:
implementation group: 'org.reflections', name: 'reflections', version: '0.9.5-RC2'
Спасибо всем за участие!
