Could not find com.android.tools.build:gradle:3.5

I'm trying to update gradle from 1.3.1 to 3.5, as some of my dependencies requires version 3.3 or above.

I've seen similar questions, but none of them help.

        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5'

distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME

distributionUrl=https\://services.gradle.org/distributions/gradle-3.5-all.zip
