Não foi possível resolver este erro, atualizei o Android studio. foi através de outroesta soluções, mas não funcionou para mim, por favor me ajude ..

Erro de criação de script, método Gradle DSL não suportado encontrado: 'release ()'! As possíveis causas podem ser:
- você está usando a versão Gradle onde o método está ausente - você não aplicou o plug-in Gradle que fornece o método - ou há um erro nas configurações de Gradle do script de construção
