Как исправить ошибку Grandle?

Я хочу сделать синхронизацию Grandle.
Ошибка:

Caused by: org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method clean() for arguments [{type=class org.gradle.api.tasks.Delete}, build_497oxmpw7mywz45z8kkyrgvxg$_run_closure1$_closure7@5974b866] on object of type org.gradle.api.internal.initialization.DefaultScriptHandler.

Вот код(/Build.Grandle):

// Top-level build file where you can add configuration options common to all sub-projects/modules.
