Exclude a Kotlin Subproject From Gradle Jacoco

In my project, one of the subproject is NodeJS hence the usual Jacoco setup:

tasks.withType(Test) {
    finalizedBy jacocoTestReport
}

doesn’t work as Jacoco fails since it can’t locate test execution binary for the nodeJS project.

After some trial & error, found out this approch works:

tasks.withType(Test).each { testTask ->
    //nodeJS doesn't support jacoco
    if(!testTask.getProject().toString().contains("nodejsproject")) {
        testTask.finalizedBy(jacocoTestReport)
    }
}

then add jacoco gradle setup as usual with executionData setup:

apply plugin: 'jacoco'

jacocoTestReport {
    executionData { tasks.withType(Test).findAll { it.jacoco.destinationFile.exists() }*.jacoco.destinationFile }

    reports {
        xml.enabled true
        xml.destination(file("${jacoco.reportsDir}/xml/jacocoTestReport.xml"))
        html.enabled true
        html.destination(file("${jacoco.reportsDir}/html"))
    }
}
