Comment configurer Jacoco avec Spek dans un multi-projet?

Question

Je veux mesurer la couverture par Jacoco dans le projet model, l'un des projets de l'enfant. Cependant, après la tâche test, la tâche jacocoTestReport est ignorée.

test:

:model:compileKotlin UP-TO-DATE 
:model:compileJava UP-TO-DATE 
:model:copyMainKotlinClasses UP-TO-DATE 
:model:processResources UP-TO-DATE 
:model:classes UP-TO-DATE 
:model:compileTestKotlin UP-TO-DATE 
:model:compileTestJava UP-TO-DATE 
:model:copyTestKotlinClasses UP-TO-DATE 
:model:processTestResources UP-TO-DATE 
:model:testClasses UP-TO-DATE

:model:junitPlatformTest 
Test run finished after 113 ms 
[   4 containers found  ] 
[   0 containers skipped ] 
[   4 containers started ]

[   0 tests aborted   ] 
[   1 tests successful  ] 
[   0 tests failed   ] 
:model:test 
:model:test SKIPPED 

Ensuite, un fichier xml est sortie. (Modèle/build/test-résultats/JUnit-plateforme/TEST-spek.xml)

jacocoTestReport:

:model:compileKotlin UP-TO-DATE 
:model:compileJava UP-TO-DATE 
:model:copyMainKotlinClasses UP-TO-DATE 
:model:processResources UP-TO-DATE 
:model:classes UP-TO-DATE 
:model:jacocoTestReport SKIPPED 

build.gradle:

buildscript { 
    ext.kotlinVersion = '1.1.0' 
    repositories { 
     mavenLocal() 
     mavenCentral() 
     maven { url "https://oss.sonatype.org/content/repositories/snapshots/" } 
    } 
    dependencies { 
     classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion" 
     classpath "org.junit.platform:junit-platform-gradle-plugin:1.0.0-M3" 
    } 
} 

allprojects { 
    ext { 
     spekVersion = '1.1.0-beta3' 
    } 

    repositories { 
     mavenLocal() 
     mavenCentral() 
     jcenter() 
     maven { url "http://dl.bintray.com/jetbrains/spek" } 
     maven { url "https://oss.sonatype.org/content/repositories/snapshots/" } 
     maven { url "https://oss.sonatype.org/content/repositories/releases/" } 
    } 
} 

project(":model") { 
    apply plugin: "java" 
    apply plugin: "kotlin" 
    apply plugin: 'org.junit.platform.gradle.plugin' 
    apply plugin: "jacoco" 

    jacoco { 
     reportsDir = file("$rootProject.buildDir/reports/jacoco") 
    } 

    jacocoTestReport { 
     reports { 
      html.enabled = true 
      xml.enabled = true 
      csv.enabled = false 
     } 
    } 

    junitPlatform { 
     filters { 
      engines { 
       include 'spek' 
      } 
     } 
    } 

    dependencies { 
     compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion" 
     testCompile "org.jetbrains.spek:spek-api:$spekVersion" 
     testCompile 'org.amshove.kluent:kluent:1.14' 
     testRuntime "org.jetbrains.spek:spek-junit-platform-engine:$spekVersion" 
     testRuntime 'org.junit.platform:junit-platform-console:1.0.0-M3' 
    } 
} 

Que dois-je faire pour jacocoTestReport tâche réussie?

[EDIT]

Quand j'ajoute onlyIf, jacocoTestReport tâche est exécutée, mais il échoue encore.

jacocoTestReport { 
    onlyIf = { 
     true 
    } 
} 

La sortie:

:model:compileKotlin UP-TO-DATE 
:model:compileJava UP-TO-DATE 
:model:copyMainKotlinClasses UP-TO-DATE 
:model:processResources UP-TO-DATE 
:model:classes UP-TO-DATE 
:model:jacocoTestReport FAILED 

FAILURE: Build failed with an exception. 

* What went wrong: 
Execution failed for task ':model:jacocoTestReport'. 
> Unable to read execution data file model\build\jacoco\test.exec 

Answer 1

Par défaut, le plug-in JUnit Gradle désactive la tâche de test standard Gradle, mais cela peut être remplacé par le drapeau enableStandardTestTask. Il semble que la tâche jacocoTestReport recherche cela.

junitPlatform { 
    filters { 
     engines { 
      include 'spek' 
     } 
    } 

    enableStandardTestTask true 
}
