Синхронизация Gradle не удалась. Сборка не удалась с исключением. Ненормальный контент для build.gradle? Фатальные ошибки IDE также

Я новичок в студии Android и понятия не имею, почему Gradle Sync не удалось. Я пробовал ниже, но все не работает. 1. Перестроить проект 2. Недействительные кеши/перезапустить 3. Переустановить студию Android 4. 58024814

По словам Варо, я переместил файл проекта и .gradle в каталог без пробела, но синхронизация gradle все равно не удалась.

Ниже приведены коды ошибок в журнале сборки.

FAILURE: Build failed with an exception.
