I am getting following error message while making build
Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 16.0.0.

(*) - dependencies omitted (listed previously)

Not getting where exactly conflict is and how to solve it?

solved this by updating main gradle file as below

buildscript 
repositories 
 jcenter()
 google()


dependencies 
 classpath 'com.android.tools.build:gradle:3.2.1'
 classpath 'com.google.gms:google-services:4.0.2'
 // NOTE: Do not place your application dependencies here; they belong
 // in the individual module build.gradle files



 allprojects 
repositories 
 jcenter()
 maven url "https://jitpack.io" 
 maven 
 url "http://dl.bintray.com/piasy/maven"
 
 maven url "https://oss.sonatype.org/content/repositories/snapshots/" 
 google()



task clean(type: Delete) 
 delete rootProject.buildDir

Now getting following issue

error: duplicate value for resource 'attr/fontStyle' with config ''.
appbuildintermediatesincrementalmergeDebugResourcesmerged.dirvaluesvalues.xml:1421: error: resource previously defined here.

looks like

com.google.firebase:firebase-analytics

Using com.google.android.gms:play-services-tasks:15.0.1

Please update firebase. Try use

com.google.firebase:firebase-analytics:+

The next step is force configuration:

android
 configurations.all 
 resolutionStrategy.force "com.google.android.gms:play-services-tasks:$playServicesVersion"
 

Please check your build gradle version and update com.android.tools.build:gradle

updated main gradle file solved this conflict updated com.android.tools.build:gradle and
com.google.gms:google-services versions

buildscript 
repositories 
 jcenter()
 google()
