Ошибка - Forge gradle compiller error | Java

Здравствуйте. Я собираю свою сборку MC , и мне нужно было внести изменения в мод для баланса. Я декомпилировал и деобфускацировал class файлы так что получил .java src Внёс изменения. Теперь мне нужно компилировать это. Но что изменённая/что просто декомпилированные версии не могут скомпилироваться. Подключённые библиотеки:

GraviSuite-1.7.10-2.0.3.jar
industrialcraft-2-2.2.827-experimental-dev.jar
