Android Studio sync error Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find com.android.tools.build:gradle:3.6.3.

Could not find lint-gradle-api.jar (com.android.tools.lint:lint-gradle-api:26.1.2)

위와 같은 메시지 이거나

 

classpath 'com.android.tools.build:gradle:3.2.1'

gradle 버전 3.2.1로 올린 후 sync 시 에러가 난다면

 

buildscript {
    repositories {
    	maven {
            url 'https://dl.google.com/dl/android/maven2'
        }
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.3'
    }
}

 

jcenter() 위에 

maven {
	url 'https://dl.google.com/dl/android/maven2'
}

메이븐 url을 추가해 준다
