How to set jacoco code coverage levels to module in gradle

Question

I'm using gradle 4.3.1 with the jacoco plugin and I am able to ensure a certain level of code coverage in a a multi module project. This works great when I set the element to CLASS or PACAKAGE, but I'm stumped on how to get it work for the module.

Looking here I think what I want is BUNDLE or GROUP, but then jacoco does not break when I go under the coverage amount.

Here is an example of what I have that does work for package level coverage enforcement :

jacocoTestCoverageVerification {
    violationRules {
        rule {
            // should be element = 'BUNDLE' or 'GROUP'? 
            element = 'PACKAGE'

            limit {
                minimum = 0.9
            }
            includes = ['com.mypackage.*']
        }
    }
}

When I change the element value to BUNDLE the build does not fail regardless of coverage. Again I'd like to be able to control the expectation at the module level.

Here is my gradle version information:

I'm guessing I'm missing something pretty simple, since I don't think I'm the first to try to do this. Any help would be appreciated!

I am not very sure of this, but could you try adding counter='LINE' inside limit.

rule {
       element = 'GROUP'

       limit {
           minimum = 0.9
           counter = 'LINE'
       }
...

Apart from that also try to add jacocoTestReport for generating test report to verify your result for internal testing purpose only.

jacocoTestReport {
    reports {
        xml.enabled false
        csv.enabled false
        html.destination file("${buildDir}/jacocoHtml")
    }
}
