gradle - Kotlin 项目的 SonarQube 报告中的覆盖率为 0%

Question

我正在设置通过 SonarQube 服务器分析项目。
使用的工具集是:
Kotlin 1.3.61
Gradle 6.0.1
雅 cocoa 0.7.9
SonarQube 7.5
SonnarQube Gradle 插件 2.7

问题是我在 SonarQube 中有 0.0% 的覆盖率，但是，同时我已经形成了 jacoco 测试覆盖率报告。

以下是来自 build.gradle.tks 的片段:

 plugins {
    ...
    id("org.sonarqube") version "2.7"
}

sonarqube {
    properties {
        property("sonar.host.url", "http://localhost:9000")
        property("sonar.sources", "src/main/")
        property("sonar.tests", "src/test/")
        property("sonar.exclusions", "src/generated/")
        property("sonar.jacoco.reportPath", "build/jacoco/test.exec")
        property("sonar.junit.reportsPath","build/test-results/test")
        property("sonar.core.codeCoveragePlugin","jacoco")
        property("sonar.verbose", "true")
        property("sonar.binaries" ,"build/classes/kotlin")
        property("sonar.java.binaries" ,"build/classes/java, build/classes/kotlin")
        property("sonar.dynamicAnalysis", "reuseReports")
    }
}

jacoco {
    toolVersion = "0.7.9"
    reportsDir = file("${project.projectDir}/build/reports")
}

tasks.named("sonarqube") {
    dependsOn(tasks.named("jacocoTestReport"))
}

我在执行 ./gradlew sonarqube --info 期间有下一个日志条目:

配置有什么问题？有什么遗漏吗？

更新:

此外，我在 DEBUG 模式下执行 gradle 任务后发现了下一个条目:

[DEBUG] [org.sonarqube.gradle.SonarQubeTask] Sensors : JaCoCo XML Report Importer -> Kotlin Sensor -> SonarJavaXmlFileSensor -> XML Sensor -> Zero Coverage Sensor
[INFO]  [org.sonarqube.gradle.SonarQubeTask] Sensor JaCoCo XML Report Importer [jacoco]

Answer 1

好吧，我终于找到了这篇文章:
https://community.sonarsource.com/t/coverage-test-data-importing-jacoco-coverage-report-in-xml-format/12151

由于它
不推荐使用的 SonarJava 分析器的 5.12 版使用 JaCoCo 的二进制格式(.exec 文件)来导入覆盖率。
这种二进制格式是 JaCoCo 项目的内部格式，因此无法保证向后兼容性，因此不应将其用于集成目的。

作为替代，Sonarqube 开发团队开发了 sonar-jacoco 插件，它导入 JaCoCo 的 XML 覆盖率报告，这是现在的首选选项。

因此，为了能够阅读 Jacoco 测试覆盖率报告，我更改了属性
从

property("sonar.jacoco.reportPath", "build/jacoco/test.exec")

到

property("sonar.coverage.jacoco.xmlReportPaths", "build/jacoco/test/jacocoTestReport.xml")

而且我还添加了条款:

reports {
        xml.isEnabled = true
    }

到 jacocoTestReport gradle 任务。

所以，现在我在 :sonarqube Gradle 任务执行的日志中有以下内容:

[DEBUG] [org.sonarqube.gradle.SonarQubeTask] Sensors : JaCoCo XML Report Importer -> Kotlin Sensor -> SonarJavaXmlFileSensor -> XML Sensor -> Zero Coverage Sensor
[INFO] [org.sonarqube.gradle.SonarQubeTask] Sensor JaCoCo XML Report Importer [jacoco]
[DEBUG] [org.sonarqube.gradle.SonarQubeTask] Reading report '/home/xxx/project/build/jacoco/test/jacocoTestReport.xml'

和正确的 Sonarqube 报告中的测试覆盖率百分比:
