Gradle JacocoTestReports task is skipped on bamboo build server but builds fine on local machine

Question

I have a gradle script with a test task using Jacoco for reports. The build.gradle looks like this:

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }
}
apply plugin: 'com.android.application'
apply plugin: 'jacoco'
apply plugin: "sonar-runner"

repositories {
    maven { url 'https://maven.fabric.io/public' }
}

android {
    compileSdkVersion 21
    buildToolsVersion '22.0.1'

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"

        testHandleProfiling true
        testFunctionalTest true
    }

    buildTypes {
        debug {
            applicationIdSuffix ".debug"
            testCoverageEnabled true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    apply plugin: 'android-unit-test'

    dependencies {
        testCompile 'org.easytesting:fest:1.0.16'
        testCompile 'junit:junit:4.10'
        testCompile 'org.robolectric:robolectric:2.4'
        testCompile 'com.squareup:fest-android:1.0.8'
    }
}

def coverageSourceDirs = [
        '../app/src/main/java', 'src/gen'
]

task jacocoTestReport(type: JacocoReport, dependsOn: "testDebug") {
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."
    reports {
        xml.enabled = true
        html.enabled = true
    }

    classDirectories = fileTree(
            dir: './build/intermediates/classes/debug',
            excludes: ['**/R.class',
                       '**/R$*.class'
            ])
    sourceDirectories = files(coverageSourceDirs)
    executionData = files('build/jacoco/testDebug.exec')
}

sonarRunner {

    sonarProperties {

        property "sonar.projectKey", "coverage-example"
        property "sonar.projectName", "Coverage Example"
        property "sonar.projectVersion", "1.0"

        property "sonar.sources", "src/main/java"
        property "sonar.binaries", "build"
        property "sonar.test", "src/test/java"

        property "sonar.language", "java"
        property "sonar.profile", "Android Lint"
        property "sonar.android.lint.report", "lint-report.xml"
        property "sonar.dynamicAnalysis", "reuseReports"
        property "sonar.sourceEncoding", "UTF-8"

        property "sonar.junit.reportsPath", "build/outputs/reports/coverage/debug"
        property "sonar.cobertura.reportPath", "build/outputs/reports/coverage/debug/cobertura.xml"
        property "sonar.java.coveragePlugin", "cobertura"

        property "sonar.host.url", "https://sonar.domain.com"

        property "sonar.jdbc.url", "jdbc:mysql://sonar.domain.com:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance"

        property "sonar.jdbc.username", "someuser"
        property "sonar.jdbc.password", "somepass"
    }

}

Running on the local machine all tests runs and I get the reports as expected. But running on the bamboo server I can see in the log that the task is skipped:

Since I don't get any errors I don't understand what the problem is. Gradle is executed with the gradle-wrapper, so it's building with the same version on both machines. Any ideas?

EDIT:

I've looked at Running jacocoReport, but that doesn't really explain why it's working on my local machine and not on the build server. And if I add test task (with java plugin) I get the following error:

The 'java' plugin has been applied, but it is not compatible with the Android plugins.

And if I don't apply java plugin I get the following error:

Could not find method test() for arguments [build_58yd8leqt3uhm31fecj9zk2qm$_run_closure4@3a73cd3f] on project ':app'.

But maybe I'm totally misunderstanding how to use the test task? Could not find method test() for arguments [build_58yd8leqt3uhm31fecj9zk2qm$_run_closure4@3a73cd3f] on project ':app'.

Answer 1

The jacocoTestReport task is skipped when there is no coverage data to process.

Coverage data is produced when running tests. On android, the task androidTest will execute the tests.

To generate jacoco report you must run the tests with a line like this :

.\gradlew androidTest
