Using same gradle version and kotlin version worked in sample project , Its giving error in my main project .

Answer 1

After a lot of research I found out it was problem with jacoco , Thanks to this issue and its commentors in youtrack which pointed me out in right direction . To fix the issue upgrade the jacoco to version 0.8.7

in app level build.gradle file add these following lines

plugins{
    ...
    id 'jacoco'
}

jacoco {
   toolVersion = "0.8.7"
}

android {
   ...
}

dependencies{
  ...
}

configurations.all{
resolutionStrategy {
    eachDependency { details ->
        if ('org.jacoco' == details.requested.group) {
            details.useVersion "0.8.7"
        }
    }
   }
}

I am not sure why it worked in sample app

If in-case, if you use build.gradle.kts

plugins {
    ...
    jacoco
}

jacoco {
    toolVersion = "0.8.7"
}

configurations.all {
    resolutionStrategy {
        eachDependency {
            if (requested.group == "org.jacoco") {
                useVersion("0.8.7")
            }
        }
    }
}
