I updated the "distributionUrl in my "gradle/wrapper/gradle-wrapper.properties" file to match the current gradle version.

I also updated the classpath in my top level build.gradle file to match the gradle API level.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

Re-synced and then it built OK.
