SonarQube 代码覆盖率无法解释 Android 项目上的 Kotlin 文件

Question

以下是我的声纳属性片段：

sonarqube {
   properties{
      property "sonar.junit.reportPaths", "build/test-results/testDebugUnitTest/*.xml"
      property("sonar.coverage.jacoco.xmlReportPaths", "build/reports/jacocoTestReport.xml"
}
}

Jacoco 配置和属性工作正常，我如何确认这一点？我创建了一个 java 类并为其编写了一个单元测试，sonarqube 识别了这一点并将其记录为代码覆盖率的一部分，而它基本上忽略了所有 Kotlin 文件测试。我继续将 kotlin 文件更改为 java，并为其编写了一个 UnitTest，是的，它被识别并添加为代码覆盖率的一部分，再次，kotlin 文件测试被忽略。

顺便说一句，下面是我的 Jacoco.gradle：

apply plugin: 'jacoco'

ext {
    coverageExclusions = [
            '**/*Activity*.*',
            '**/*Fragment*.*',
            '**/R.class',
            '**/R$*.class',
            '**/BuildConfig.*',
    ]
}

jacoco {
    toolVersion = '0.8.6'
    reportsDir = file("$buildDir/reports")
}

tasks.withType(Test) {
    jacoco.includeNoLocationClasses = true
    jacoco.excludes = ['jdk.internal.*']
}


tasks.withType(Test) {
    finalizedBy jacocoTestReport // report is always generated after tests run
}

task jacocoTestReport(type: JacocoReport, dependsOn: ['testDebugUnitTest']) {
    group = "Reporting"
    description = "Generate Jacoco coverage reports for Debug build"

    reports {
        xml.enabled(true)
        html.enabled(true)
        xml.destination(file("build/reports/jacocoTestReport.xml"))
    }

    def debugTree = fileTree(dir: "${buildDir}/intermediates/javac/debug/classes", excludes: coverageExclusions)
    def mainSrc = "/src/main/java"

    additionalSourceDirs.from = files(mainSrc)
    sourceDirectories.from = files([mainSrc])
    classDirectories.from = files([debugTree])

    executionData.from = fileTree(dir: project.buildDir, includes: [
            'jacoco/testDebugUnitTest.exec', 'outputs/code-coverage/connected/*coverage.ec'
    ])

Answer 1

经过大量的研究和调试，以及上面@LarryX 答案的信息，我能够按照他所说的方式使用这些类，下面是我的工作Jacoco.gradle文件。

apply plugin: 'jacoco'

jacoco {
    toolVersion = "0.8.4"
}

tasks.withType(Test) {
    jacoco.includeNoLocationClasses = true
    jacoco.excludes = ['jdk.internal.*']
}

project.afterEvaluate {
    (android.hasProperty('applicationVariants')
            ? android.'applicationVariants'
            : android.'libraryVariants')
            .all { variant ->
                def variantName = variant.name
                def unitTestTask = "test${variantName.capitalize()}UnitTest"
                def androidTestCoverageTask = "create${variantName.capitalize()}CoverageReport"

                tasks.create(name: "${unitTestTask}Coverage", type: JacocoReport, dependsOn: [
                        "$unitTestTask",
                        "$androidTestCoverageTask"
                ]) {
                    group = "Reporting"
                    description = "Generate Jacoco coverage reports for the ${variantName.capitalize()} build"

                    reports {
                        html.enabled(true)
                        xml.enabled(true)
                        csv.enabled(true)
                    }

                    def excludes = [
                            // data binding
                            'android/databinding/**/*.class',

                            // android
                            '**/R.class',
                            '**/R$*.class',
                            '**/BuildConfig.*',
                            '**/Manifest*.*',
                            '**/*Test*.*',

                            '**/Manifest*.*',
                            '**/*$Lambda$*.*',
                            '**/*Companion*.*',
                            '**/*Module*.*',
                            '**/*Dagger*.*',
                            '**/*Hilt*.*',
                            '**/*MembersInjector*.*',
                            '**/*_MembersInjector.class',
                            '**/*_Factory*.*',
                            '**/*_Provide*Factory*.*',
                            '**/*Extensions*.*',
                            // sealed and data classes
                            '**/*$Result.*',
                            '**/*$Result$*.*'
                    ]

                    def javaClasses = fileTree(dir: variant.javaCompileProvider.get().destinationDir,
                            excludes: excludes)
                    def kotlinClasses = fileTree(dir: "${buildDir}/tmp/kotlin-classes/${variantName}",
                            excludes: excludes)

                    classDirectories.setFrom(files([
                            javaClasses,
                            kotlinClasses
                    ]))

                    def variantSourceSets = variant.sourceSets.java.srcDirs.collect { it.path }.flatten()
                    sourceDirectories.setFrom(project.files(variantSourceSets))

                    def androidTestsData = fileTree(dir: "${buildDir}/outputs/code_coverage/${variantName}AndroidTest/connected/", includes: ["**/*.ec"])

                    executionData(files([
                            "$project.buildDir/jacoco/${unitTestTask}.exec",
                            androidTestsData
                    ]))
                }

            }
}

记笔记 ：

  def javaClasses = fileTree(dir: variant.javaCompileProvider.get().destinationDir,
                        excludes: excludes)
                def kotlinClasses = fileTree(dir: "${buildDir}/tmp/kotlin-classes/${variantName}",
                        excludes: excludes)

                classDirectories.setFrom(files([
                        javaClasses,
                        kotlinClasses
                ]))

另外，请注意project.afterEvaluate我不确定这是否相关，但因为我认为您必须在本节运行之前运行并生成测试。如果不是实际的 Android 应用程序，此解决方案也适用于库。

然后是我的sonarqube.gradle文件如下。

apply plugin: "org.sonarqube"

    sonarqube {
        properties {
            property "sonar.host.url", "http://localhost:9000/"
            property "sonar.projectKey", "fair"
            property "sonar.projectName", "fair"
            property "sonar.login", "de9d79fe4d3aef9879567afc91a2ce465038d9be"
            property "sonar.projectVersion", "${android.defaultConfig.versionName}"
    
            property "sonar.junit.reportsPath", "build/test-results/testDebugUnitTest"
            property "sonar.java.coveragePlugin", "jacoco"
            property "sonar.sourceEncoding", "UTF-8"
            property "sonar.android.lint.report", "build/reports/lint-results.xml"
            property "sonar.jacoco.reportPaths", "build/jacoco/testDebugUnitTest.exec"
            property "sonar.jacoco.itReportPath", fileTree(dir: project.projectDir, includes: ["**/*.ec"])
            property "sonar.coverage.jacoco.xmlReportPaths", "build/reports/jacoco/testDebugUnitTestCoverage/testDebugUnitTestCoverage.xml"
        }
    }
    tasks.sonarqube.dependsOn ":app:testDebugUnitTestCoverage"

最后我的build.gradle(project)

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.32"
        classpath "org.jacoco:org.jacoco.core:0.8.7"
        classpath("org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:3.3")
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
