我已经建立了一个基本的kotlin项目（空类，一个测试文件），并尝试使用gradle的插件设置jaoco with gradle：https://docs.gradle.org/current/userguide/jacoco_plugin.html

当我运行测试时，一个测试通过了，但是没有创建Jacoco. exec文件。我错过了什么？我假设这些类从未被检测过，但似乎找不到太多关于如何为Jacoco设置build.gradle的信息。或者Jacoco不能检测从kotlin创建的类文件？

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 test时，我希望创建一个build/jacoco/jacoco. exec文件，但事实并非如此。

:test SKIPPED

BUILD SUCCESSFUL

当我查看构建目录时，没有创建Jacoco文件夹：

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

任何帮助或提示将不胜感激！

谢谢你！
