I have configured my app build.gradle with free and paid version with different keystores. look at the code below.

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

android 
 signingConfigs 
 freeProdRelease 
 keyAlias 'free.prod.release.key'
 keyPassword 'password'
 storeFile file('F:/freeProdRelease.jks')
 storePassword 'password'
 
 paidProdRelease 
 keyAlias 'paid.prod.release.key'
 keyPassword 'password'
 storeFile file('F:/paidProdRelease.jks')
 storePassword 'password'

What I want is when I change my variant freeProdRelease or paidProdRelease and create release build then keystore file should be selected according to variant. for that I have setup code below

if(variant.buildType.name == "release") 
 if(variant.productFlavors[0].name == "paid") 
 android.buildTypes.release.signingConfig android.signingConfigs.paidProdRelease
 else 
 android.buildTypes.release.signingConfig android.signingConfigs.freeProdRelease
 

When I remove the above code then It gives error for release build and that is fine.

But when I commented else block and creating release build it still works and doesn't give error for keystore file, It means each time keystore file will be used paidProdRelease that I don't want.

if(variant.buildType.name == "release") 
 if(variant.productFlavors[0].name == "paid") 
 android.buildTypes.release.signingConfig android.signingConfigs.paidProdRelease
 else 
// android.buildTypes.release.signingConfig android.signingConfigs.freeProdRelease
 

What should I do to use different keystore file for respected version free/paid?
