Jacoco gradle with subprojects.

[marcofranssen]

Do you have any idea on how to merge the jacoco reports of a multi module gradle project?

plugins {
    id "org.sonarqube" version "2.7"
    id 'jacoco'
}

def allTestCoverageFile = "${buildDir}/jacoco/allTestCoverage.exec"

// This seems to be a jacoco task which can be used to merge reports.
task jacocoMerge(type: JacocoMerge, group: 'verification') {
    // ??????????????????????????????????????????
}

sonarqube {
    properties {
        property "sonar.scm.provider", "git"
        property "sonar.jacoco.reportPaths", allTestCoverageFile
    }
}

subprojects {
    apply plugin: 'java'
    apply plugin: 'jacoco'

    sonarqube {
        properties {
            property "sonar.jacoco.reportPaths", allTestCoverageFile
        }
    }
}

project(':projectA') {
    dependencies {
        compile project(':projectB')
        compile project(':projectC')
    }
}

project(':projectB') {
    dependencies {
        compile project(':projectC')
    }
}

project(':projectC') {
    dependencies {
    }
}
