SonarQube没有显示Gradle多项目中JUnit测试的测试Jacoco覆盖率

Question

我想展示用Gradle 6.0构建的多项目Spring boot应用程序的测试覆盖范围。我们目前使用JUnit5。

SonarQube中的测试覆盖率为0%，尽管存在一些首次测试。

顶层项目（https://github.com/OpenReqEU/eclipse-plugin-vogella/blob/master/server/build.gradle）中的build.gradle文件有以下输入：

plugins {
    id "org.sonarqube" version "2.7"
    id 'jacoco'
}

repositories {
    jcenter()
}

subprojects {
    apply plugin: 'jacoco'
    apply plugin: 'java'
    apply plugin: 'eclipse'

    repositories {
        jcenter()
        maven { url 'https://repo.spring.io/snapshot' }
        maven { url 'https://repo.spring.io/milestone' }
        maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' }
            maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local/' }
    }

    jacocoTestReport {
        reports {
            xml.enabled true
            xml.destination file("${buildDir}/coverage-reports/coverage.xml")
            //html.destination file("${buildDir}/coverage-reports")
        }
    }

    ext {
        springBootVersion = '2.1.1.RELEASE'
    }

    sourceCompatibility = 1.8

}


wrapper {
    gradleVersion = '6.0'
}

在Jenkins构建中，我们设置了以下参数：

sonar.projectKey=eclipse-plugin-vogella
sonar.sources=server/com.vogella.prioritizer.server/src/main,server/com.vogella.prioritizer.server.bugzilla/src/main,server/com.vogella.prioritizer.server.issue.api/src/main
sonar.java.binaries=com.vogella.prioritizer.server/build/classes/java/main,com.vogella.prioritizer.server.bugzilla/build/classes/java/main,com.vogella.prioritizer.server.issue.api/build/classes/java/main
sonar.tests=server/com.vogella.prioritizer.server/src/test,server/com.vogella.prioritizer.server.bugzilla/src/test
sonar.coverage.jacoco.xmlReportsPath=server/com.vogella.prioritizer.server.bugzilla/build/jacoco/test.exec,server/com.vogella.prioritizer.server/build/jacoco/test.exec,server/com.vogella.prioritizer.server.issue.api/build/jacoco/test.exec

生成结果显示错误：信息：解析[/home/jenkins/workspace/issue-priorizer/coverage-reports/coverages.xml]错误：未找到报告路径或报告路径不是目录：/home/jenkins/workspace/ission-prioriizer/coveration-reports/coverge.xml

我看到每个项目都有一个生成的${buildDir}/coverage-report/coverage.xml文件，但根文件是空的，这是意料之中的，因为我没有配置与此相关的任何内容。

在某个时候，我添加了一个复制任务，将一个项目中的一个生成的xml文件复制到根文件夹中，但是构建作业抱怨这些类不匹配。

有人知道如何解决这个问题吗？我假设我必须添加一个配置来添加一个根coverage.xml文件，它是单个文件的集合，但我还没有找到解决方案。

我还尝试将jacoco应用于根项目，但这也失败了，因为根项目不是Java项目。

我设法创建了聚合覆盖率。通过更改顶级构建来创建xml文件。gradle to：

plugins {
//    id "org.sonarqube" version "2.7"
    id 'jacoco'
}

repositories {
    jcenter()
}


subprojects {

    println name;
    apply plugin: 'jacoco'
    apply plugin: 'java'
    apply plugin: 'eclipse'

    repositories {
        jcenter()
        maven { url 'https://repo.spring.io/snapshot' }
        maven { url 'https://repo.spring.io/milestone' }
        maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' }
        maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local/' }
    }

    jacocoTestReport {   
        reports {
            xml.enabled true
        }
    }

    ext {
        springBootVersion = '2.1.1.RELEASE'
    }

    sourceCompatibility = 1.8
}

// run the build with ./gradlew clean build generateMergedReport
task generateMergedReport(type: JacocoReport) {
    dependsOn = subprojects.test 

    additionalSourceDirs.setFrom files(subprojects.sourceSets.main.allSource.srcDirs)
    sourceDirectories.setFrom files(subprojects.sourceSets.main.allSource.srcDirs)
    classDirectories.setFrom files(subprojects.sourceSets.main.output)

    executionData.setFrom project.fileTree(dir: '.', include: '**/build/jacoco/test.exec')
    println executionData;

    reports {
        xml.enabled true
        xml.destination file("../coverage-reports/coverage.xml")
    }
}

wrapper {
    gradleVersion = '6.0'
}

并更改了Jenkins以构建generateMergedReport:

cd server && ./gradlew build generateMergedReport

SonarQube属性更改为：

sonar.projectKey=eclipse-plugin-vogella
sonar.sources=server/com.vogella.prioritizer.server/src/main,server/com.vogella.prioritizer.server.bugzilla/src/main,server/com.vogella.prioritizer.server.issue.api/src/main
sonar.java.binaries=com.vogella.prioritizer.server/build/classes/java/main,com.vogella.prioritizer.server.bugzilla/build/classes/java/main,com.vogella.prioritizer.server.issue.api/build/classes/java/main

不幸的是，SonarQube仍然没有找到coverage.xml文件。

INFO: parsing [/home/jenkins/workspace/issue-prioritizer/coverage-reports/coverage.xml]
ERROR: Reports path not found or is not a directory: /home/jenkins/workspace/issue-prioritizer/coverage-reports/coverage.xml

有人知道缺少什么吗？

Answer 2

需要生成xml格式的报告。将sonar属性添加到xml路径，如下所示。

jacocoTestReport {
    reports {
        xml.enabled true
    }
}

sonarqube {
        properties {
            property "sonar.java.source", "1.8"
            property "sonar.java.coveragePlugin", "jacoco"
            property "sonar.jacoco.reportPaths", "build/reports/jacoco/test/jacocoTestReport.xml"
        }
}

使用jacocoTestReport运行gradle命令

gradlew sonarqube jacocoTestReport
