Jacoco Unit Test code coverage is zero?

Hi,
I am trying to determine the code coverage but I am amazed to find that Jacoco plugin reports zero unit test coverage although a sizeable amount of unit tests exist.

Am I missing something here?

Look at my question on stackoveflow: https://stackoverflow.com/questions/45350561/android-studio-3-kotlin-code-coverage

Run gradlew copyTestClasses then generate code coverage.

so I did a clean testDebug copyTestClasses createDebugCoverageReport

coverage report gets generated here: application/build/reports/coverage/debug/

still shows 0%

So I think generating code coverage report is still a problem with kotlin and Android Studio 3. I need to look at this.
I found: https://issuetracker.google.com/issues/64929213

After some tinkering I can see the jacoco prepared report for the ui sub-package but gradle plugin prepared coverage report is still 0%.
I will post back my findings after tinkering with coverage report 🛠
