How to enable code coverage with Kotlin dsl gradle?

Question

When enabling jacoco with gradle kotlin dsl it fails because it looks at build.gradle file instead of build.gradle.kts file.

Here is the error :

##[warning]Unable to append code coverage data: Error: File or folder doesn't exist: /home/vsts/work/1/s/build.gradle
##[warning]Failed to enable code coverage: Unable to append code coverage data: Error: File or folder doesn't exist: /home/vsts/work/1/s/build.gradle

app/build.gradle.kts

plugins {
    jacoco
}

tasks.withType(JacocoReport::class.java).all {
    reports {
        xml.isEnabled = true
        xml.destination = File("$buildDir/reports/jacoco/report.xml")
    }
}

tasks.withType<Test> {
    jacoco {
        toolVersion = "0.8.3"
        reportsDir = file("$buildDir/reports/jacoco")
    }
    finalizedBy("jacocoTestReport")
}

are produced by AzureDevOps Gradle Task due to usage of option

codeCoverageToolOption: 'jaCoCo'

in your configuration of this task, because implementation of AzureDevOps Gradle Task contains hardcoded value build.gradle:

quoting comment from the above bug ticket

The way for you to use code coverage would be to enable it in your build config files and publish them using another task - PublishCodeCoverageResults

Hey @Godin I have written isTestCoverageEnabled = true in my build.gradle.kts so is that enough you mean to say if yes then at which path will it generate the report.

The answer on question about path is in your configuration - you have xml.destination = File("$buildDir/reports/jacoco/report.xml") and reportsDir = file("$buildDir/reports/jacoco")

Hey @Godin I have getting error "Task 'jacocoRootReport' not found in root project" when I build the solution is there any other file do I need to change.
