如何为多模块项目创建汇总的 Jacoco 报告？

Question

几天来，我一直在寻找一种解决方案，用于合并多模块 Android 项目的多个Jacoco报告，以便立即将它们发送到Sonarcloud 。 我已经检查了大量 Stackoverflow 帖子和其他内容，例如博客、Github 存储库、 Gradle 论坛等，但不幸的是，没有一个解决方案适合我。

如果有人在这里与我分享示例项目或代码片段，我将不胜感激。

Gradle version: 7.0.2
Kotlin version: 1.5.21
JDK: 11

下面的代码段也不适合我

/**
 *  Root task that generates an aggregated Jacoco test coverage report for all sub-projects
 */
task jacocoFullReport(type: JacocoReport, group: 'Coverage reports') {
    group = 'Reporting'
    description = 'Generates an aggregate report from all subprojects'

    tasks.withType(Test) {
        ignoreFailures true
    }

    def projects = subprojects

    //noinspection GrUnresolvedAccess
    dependsOn(projects.jacocoReport)

    final source = files(projects.jacocoReport.sourceDirectories)

    additionalSourceDirs.setFrom source
    sourceDirectories.setFrom source

    classDirectories.setFrom files(projects.jacocoReport.classDirectories)
    executionData.setFrom files(projects.jacocoReport.executionData)

    reports {
        html {
            enabled true
            destination file('build/reports/jacoco/html')
        }
        csv {
            enabled true
            destination file('build/reports/jacoco/jacocoFullReport.csv')
        }
    }

    doFirst {
        //noinspection GroovyAssignabilityCheck
        executionData.setFrom files(executionData.findAll { it.exists() })
    }
}

这里的工作示例如何创建聚合 jacoco 报告： https://github.com/SurpSG/jacoco-gradle-plugin-merge-coverage

task jacocoRootReport(type: JacocoReport, group: 'Coverage reports') {
    description = 'Generates an aggregate report from all subprojects'
    dependsOn(subprojects.test)

    additionalSourceDirs.from = files(subprojects.sourceSets.main.allSource.srcDirs)
    sourceDirectories.from = files(subprojects.sourceSets.main.allSource.srcDirs)
    classDirectories.from = files(subprojects.sourceSets.main.output)
    executionData.from = files(subprojects.jacocoTestReport.executionData)

    reports {
        html.enabled true
    }
}

我刚刚创建了这个演示项目，说明了如何使用buildSrc ad-hoc 插件进行归档，该插件依赖于 Gradle 的jacoco-report-aggregation和 Android Gradle 插件的原生jacoco支持。

稍后您可以通过将其添加到根项目中轻松地将其与sonarqube链接：

plugins {
    coverage // comes from `buildSrc/src/main/kotlin/coverage.gradle.kts`
    id("org.sonarqube") version "3.4.0.2513"
}

sonarqube {
    properties {
        tasks.jacocoTestReport.configure {
            property("sonar.coverage.jacoco.xmlReportPaths", reports.xml.outputLocation.get().asFile)
        }
    }
}

tasks.sonarqube.configure {
    dependsOn(tasks.jacocoTestReport)
}
