带有gradle和kotlin的jacoco并未创建jacoco.exec文件

Question

我已经设置了一个基本的kotlin项目（空类，一个测试文件），并尝试使用gradle插件与gradle设置jacoco：https：//docs.gradle.org/current/userguide/jacoco_plugin.html

当我运行测试时，一个测试会通过，但是没有jacoco.exec文件创建。我想念什么？我认为这些课程永远不会得到仪器，但似乎找不到有关如何设置build.jacoco的太多信息。还是可以通过Kotlin创建的仪器类文件？

group 'com.ronnev.filewatcher'
version '0.1'
buildscript {
    ext.kotlin_version = '1.1.61'
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.2'
    }
}
apply plugin: 'kotlin'
apply plugin: 'org.junit.platform.gradle.plugin'
apply plugin: 'jacoco'
repositories {
    mavenCentral()
    jcenter()
}
dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
    testCompile 'org.junit.jupiter:junit-jupiter-api:5.0.2'
    testRuntime 'org.junit.jupiter:junit-jupiter-engine:5.0.2'
}
jacoco {
    toolVersion = "0.7.9"
    reportsDir = file("$buildDir/jacoco/")
}
jacocoTestReport {
    classDirectories = files("${buildDir}/classes")
    reports {
        xml.enabled true
        csv.enabled false
        html.destination file("${buildDir}/jacoco/jacocoHtml")
    }
}
test {
    jacoco {
        append = false
        destinationFile = file("$buildDir/jacoco/jacocoTest.exec")
    }
}

当我运行gradle测试时，我希望创建一个构建/jacoco/jacoco.exec文件，但不是。

vextorspace@vPrecise:~/projects/filewatcher $ gradle clean test

[         1 tests successful      ]
[         0 tests failed          ]
:test SKIPPED
BUILD SUCCESSFUL

当我在构建目录中查看时，没有创建jacoco文件夹：

vextorspace@vPrecise:~/projects/filewatcher $ ls build
classes  kotlin  kotlin-build  kotlin-classes  resources  test-results

任何帮助或提示都将不胜感激！

谢谢！

jacoco尚无法将自己连接到Juint5使用的新任务名称（例如junitPlatformTest）。

您需要"帮助" gradle才能使用task.dependsOn(otherTask)方法调用来创建两个任务之间的连接。

在您的情况下，将其添加到您的构建中。

jacoco {
    // This is the latest version at the time of writing this. Change as you need.
    toolVersion = '0.7.9'
    applyTo junitPlatformTest
}
test.dependsOn junitPlatformTest
