Gradle 包含多个子模块的 jacoco 覆盖率报告？

Question

有谁知道如何为 java jacoco 报告配置 gradle 文件包含多个 gradle 个子模块的代码覆盖率？

我目前的方法只显示当前子模块的代码覆盖率，但不显示兄弟子模块的代码覆盖。

我有这个项目结构

- build.gradle (1)
- corelib/
    - build.gradle (2)
    - src/main/java/package/Core.java
- extlib/
    - build.gradle (3)
    - src/main/java/package/Ext.java
    - src/test/java/package/Integrationtest.java

当我执行 gradlew :extlib:check :extlib:jacocoTestReport junit-test "Integrationtest.java" 被执行并生成一个代码覆盖率报告，其中不包含 corelib 类的代码覆盖率，例如 Core.java

结果应包括 Ext.java 和 Core.java

的代码覆盖

我已经阅读了

却没有发现任何线索

这里是 gradle 个文件的内容

// root build.gradle (1)
// Top-level build file where you can add configuration options 
// common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }
}
allprojects {
    repositories {
        jcenter()
    }
}

// build.gradle (2) subproject build file for corelib.
apply plugin: 'java'
apply plugin: 'jacoco'

dependencies {
}

jacocoTestReport {
    reports {
        xml.enabled true
        html.enabled true
    }
}

// build.gradle (3) subproject build file for extlib.
apply plugin: 'java'
apply plugin: 'jacoco'

dependencies {
    compile project(':corelib')
    testCompile 'junit:junit:4.11'

    // this does not compile
    // jacocoTestReport project(':pixymeta-core-lib')
}

jacocoTestReport {
    reports {
        xml.enabled true
        html.enabled true
    }
}

// workaround because android-studio does not make the test resources available
// see https://code.google.com/p/android/issues/detail?id=64887#c13
task copyTestResources(type: Copy) {
    from sourceSets.test.resources
    into sourceSets.test.output.classesDir
}
processTestResources.dependsOn copyTestResources

感谢@Benjamin Muschko 我也在根 gradle 文件中尝试过

// https://discuss.gradle.org/t/merge-jacoco-coverage-reports-for-multiproject-setups/12100/6
// https://docs.gradle.org/current/dsl/org.gradle.testing.jacoco.tasks.JacocoMerge.html
task jacocoMerge(type: JacocoMerge) {
   subprojects.each { subproject ->
      executionData subproject.tasks.withType(Test)
   } 

}

但收到错误消息（gradle-2.14）

* What went wrong:
Some problems were found with the configuration of task ':jacocoMerge'.
> No value has been specified for property 'jacocoClasspath'.
> No value has been specified for property 'executionData'.
> No value has been specified for property 'destinationFile'.

还有 gradle 插件 https://github.com/paveldudka/JacocoEverywhere where i have asked for mulit-submodule support https://github.com/paveldudka/JacocoEverywhere/issues/16

[更新 2016-08-01] 我找到了一个基于 https://github.com/palantir/gradle-jacoco-coverage

的可行解决方案

请参阅下面我自己的回答

Answer 1

您将需要创建类型为 JacocoMerge that aggregates the JaCoCo reports from all subprojects. See a similar discussion in this post 的新任务。

Answer 2

最后我找到了这个插件：https://github.com/palantir/gradle-jacoco-coverage 它为我完成了工作：

root gradle.build

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        // see https://jcenter.bintray.com/com/android/tools/build/gradle/
        classpath 'com.android.tools.build:gradle:2.1.0'
        // classpath 'com.android.tools.build:gradle:2.2.0-alpha1'

        // https://github.com/palantir/gradle-jacoco-coverage
        classpath 'com.palantir:jacoco-coverage:0.4.0'      
    }
}

// https://github.com/palantir/gradle-jacoco-coverage
apply plugin: 'com.palantir.jacoco-full-report'

具有

的所有子项目

apply plugin: 'jacoco'

包含在报告中。

一种可能的解决方案（带有一些声纳特定部件）：

def getJacocoMergeTask(Project proj){
    def jmClosure =  {
        doFirst {
            logger.info "${path} started"
            executionData.each { ed ->
                logger.info "${path} data: ${ed}"
            }
        }
        onlyIf {
            executionData != null && !executionData.isEmpty()
        }
    }

    def jacocoMerge = null
    if(!proj.tasks.findByName('jacocoMerge')){

        jacocoMerge = proj.tasks.create('jacocoMerge', JacocoMerge.class)
        jacocoMerge.configure jmClosure

        // sonar specific part
        proj.rootProject.tasks["sonarqube"].mustRunAfter jacocoMerge

        proj.sonarqube {
            properties {
                property "sonar.jacoco.reportPaths", jacocoMerge.destinationFile.absolutePath
            }
        }
        // end of sonar specific part

        logger.info "${jacocoMerge.path} created"
    } else {
        jacocoMerge = proj.tasks["jacocoMerge"]
    }
    jacocoMerge
}


afterEvaluate { project ->
    def jacocoMerge = getJacocoMergeTask(project)

    project.tasks.withType(Test) { task ->
        logger.info "${jacocoMerge.path} cfg: ${task.path}"

        task.finalizedBy jacocoMerge
        jacocoMerge.dependsOn task

        task.doLast {
            logger.info "${jacocoMerge.path} executionData ${task.path}"
            jacocoMerge.executionData task
        }

        def cfg = configurations.getByName("${task.name}Runtime")
        logger.info "${project.path} process config: ${cfg.name}"

        cfg.getAllDependencies().withType(ProjectDependency.class).each { pd ->
            def depProj = pd.dependencyProject
            logger.info "${task.path} dependsOn ${depProj.path}"
            def jm = getJacocoMergeTask(depProj)

            task.finalizedBy jm
            jm.dependsOn task

            task.doLast {
                logger.info "${jm.path} executionData ${task.path}"
                jm.executionData task
            }
        }
    }
}

这将合并来自所有项目的所有执行数据，这些项目在测试期间将某个项目用作依赖项。

Answer 4

您可以在没有合并 exec 文件的情况下创建合并报告。使用以下内容在 build.gradle 的根目录中创建一个新任务。

task jacocoReport(type: JacocoReport) {
    for (p in allprojects) {
        def testTask = p.tasks.findByName("test")
        if (testTask != null)
            dependsOn(testTask)

        executionData.setFrom(file("${p.buildDir}/jacoco/test.exec"))
        classDirectories.from(file("${p.buildDir}/classes/java/main"))
    }
}

Answer 5

这对我有用

plugins {
    id 'org.kordamp.gradle.jacoco' version '0.43.0'
}

config {
    coverage {
        jacoco {
            enabled
            aggregateExecFile
            aggregateReportHtmlFile
            aggregateReportXmlFile
            additionalSourceDirs
            additionalClassDirs
        }
    }
}
