Firebase Dependencies Causing Gradle Build Errors - Program Type Already Present

Question

I have recently updated my Build.Gradle files, and my project is not building successfully. After researching several possible issues, I came across [this post][1] that indicates it may be a conflict with my Firebase dependencies. It could also have to do with multidex, but based on how vague the error is I do not even have a starting point:

Error:

Program type already present: android.arch.core.util.Function   

Build.Gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'

    defaultConfig {
        vectorDrawables.useSupportLibrary = true

Add these dependencies:

implementation "android.arch.core:runtime:$version"
implementation "android.arch.core:common:$version"
