Question

有没有人知道Kotlin是否存在一个好的测试覆盖率工具（最好是Gradle插件）？我对JaCoCo进行了一些调查，但似乎没有可靠地支持Kotlin。

Answer 1

根据要求，这是一个使用Kotlin的示例build.gradle，它包含Jacoco和Sonarqube集成，生成jar和源，并在Detekt中进行静态分析。

我不得不手动添加一些东西，因为我的工作版本已经通过内部插件应用了jacoco。

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.2.10'
    id 'org.jetbrains.kotlin.plugin.spring' version '1.2.10'
    id 'org.springframework.boot' version '1.5.9.RELEASE'
    id 'io.spring.dependency-management' version '1.0.4.RELEASE'
    id 'io.gitlab.arturbosch.detekt' version '1.0.0.RC6'
    id "org.sonarqube" version "2.6.2".  
}

apply plugin: 'jacoco'

ext {
    springBootVersion = '1.5.9.RELEASE'
    springCloudVersion = 'Dalston.SR4'
    kotlinVersion = '1.2.10'
    detektVersion = '1.0.0.RC6'.  
}
