Combine unit test reports from multiple Gradle build projects

I have several modules Gradle script with three modules: common, servicesand web.

If I run gradle check, all test packages run correctly, but I don't have one test report, instead I found a test report for each subproject. How can I combine test results?

If this is useful, this is the script I am using https://github.com/CarloMicieli/trenako/blob/master/build.gradle

Thanks Carlo
