Print Coverage Total for All Projects

[apsoyka]

This feature would be helpful when working with GitLab CI, which expects a single coverage value and therefore uses only the last project's coverage value as the total coverage value.

This is achievable provided you combine your coverage tool's coverage reports into a single coverage report and then configure the console-reporter in the top level build.gradle to access it, like this:

consoleReporter {
    jacoco {
        reportFile = ["${buildDir}/reports/jacoco/test/jacocoTestReport.xml"]
    }
}

I also need a "Total Coverage" for all projects but can't seem to get this to work. If I run gradlew clean build, I automatically get the coverage of each of the Gradle sub projects' coverage.

I added a separate task that aggregates the reports from all sub projects and creates a separate single coverage report. I can view this combined report from "rootProjectDir/build/reports/jacoco/rootCoverageReport/rootCoverageReport.xml"

I configured this plugin based on the recommendation mentioned above by pointing reportFile to above mentioned path, but if I run reportJacoco task, the "Coverage summary" section still shows 0.0%
