Circle CI 2.0 Android assembleDebug всегда терпит неудачу

Каждый раз, когда Circle CI запускает ./gradlew assembleDebug часть, всегда происходит сбой. Я не знаю, в чем проблема, но я пробовал много способов, например, запускал его с daemon и без него или настраивал gradle.properties. Я искал ответы в Google и SO, но до сих пор не могу найти правильный. Вот ошибка

Демон сборки Gradle неожиданно исчез (возможно, он был убит или произошел сбой)

Вот мой config.yml

Очень ценю любые комментарии / ответы, работаю над этим 2 дня назад.
