Gradle jacocoTestReport not producing report

Question

I have tried to get code coverage in a spring-gradle project using gradle jacoco plugin.

The build.gradle contains the following

apply plugin: "jacoco"

jacoco {
  toolVersion = "0.7.1.201405082137"
  reportsDir = file("$buildDir/customJacocoReportDir")
}
    
jacocoTestReport {
  reports {
    xml.enabled false
    csv.enabled false
    html.destination "${buildDir}/jacocoHtml"
  }
}

I then ran

gradle test jacocoTestReport

Where after only the file test.exec is generated in build/reports folder.

Other than that nothing happens.

How can I get the HTML report?

test {
    jacoco {
        append = false
        destinationFile = file("$buildDir/jacoco/jacocoTest.exec")
        classDumpFile = file("$buildDir/jacoco/classpathdumps")
    }
}


jacocoTestReport {
    reports {
