Jacoco coverage not working

Hi,

I have been trying to get sonar code coverage working, with no luck so far. It used to work, so it's more like I'm trying to fix something, but it has been a long time, since it got broken...

The thing is... if I run my build locally, then everything is fine... gradle jacoco plugin generates code coverage exec files at each module level and an aggregated report in the root directory. At the end of such an execution I can see code coverage on sonar dashboard page. However, if I run the same command in TeamCity, then I can see jacoco exec files present in each module build directory, but there is no $rootDir/build/jacoco directory after a successful build, and code coverage shows as 0%.

The command I use is:

$ gradle clean test sonarRunner

Gradle configuration:

jacoco {
    toolVersion = "0.7.9"
    reportsDir = file("$buildDir/jacoco/reports")
}

test {
    jacoco {
        append true
        destinationFile file("$rootDir/build/jacoco/test.exec")
        reports {
            html {
                enabled true
                destination "$buildDir/jacoco/test"
            }
        }
    }
    maxParallelForks = 4
}

And top level configuration:

apply plugin: 'org.sonarqube'


sonarqube {

    properties {
        property "sonar.junit.reportsPath", "$buildDir/test-results"
        property "sonar.jacoco.reportPath", "$rootDir/build/jacoco/test.exec"
        property "sonar.jacoco.itReportPath", "$rootDir/build/jacoco/acceptanceTest.exec"
        property "sonar.jacoco.excludes", "*/st/*"
        property "sonar.projectKey", projectKey
        property "sonar.projectName", description
        property "sonar.projectDescription", description
        property "sonar.projectVersion", version
        property "sonar.host.url", "${project.sonarUrl}"
        property "sonar.login", "${project.sonarLogin}"
        property "sonar.password", "${project.sonarPassword}"
        property "sonar.java.coveragePlugin", "jacoco"
        property "sonar.groovy.coveragePlugin", "jacoco"
        property "sonar.exclusions", [
            "**/org/apache/**",
            "**/org/springframework/**",
            "**/static/**",
            "**/public/vendor/**",
            "**/public/js/**",
            "**/main/groovy/**/testutils/**"
        ]
    }
}

task sonarRunner(dependsOn: 'sonarqube')

Thanks,
Marcin
