java - 如何使用gradle在android项目中生成jacoco报告

Question

在java项目中很简单，gradle的示例文件夹中有两个实例。但是当我尝试在 android 项目中这样做时，出现了很多问题。

无法添加

{apply plugin: 'java'}

和

test {
    jacoco{
        excludes = ['org/bla/**']
        includes = ['com/bla/**']
        append = false
    }
}

和android插件有些冲突，test是属于java插件的，不知道怎么办。我可以进行构建、checkstyle、pmd、findbugs 和测试，但 jacoco 报告。

我的gradle文件如下:

//Import android test dependencies
import com.android.build.gradle.api.TestVariant


//Load classpath and define the repository.
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}


//Sub project,we can add a lot of sub project here.
project('TVEAndroid')
{

    //Load plugins
    apply plugin: 'android'
    apply plugin: 'jacoco'
    apply plugin: 'checkstyle'
    apply plugin: 'findbugs'
    apply plugin: 'pmd'


    //This is different with the one above,the previous one is just for load classpath,this one is for the real build.
    repositories {
        mavenCentral()
        }

    //Load dependencies,We will use nesux to hold the repositories in the future,so it will be changed.
    dependencies {
        compile fileTree(dir: 'libs', include: '*.jar')
    }

    //Jacoco plugin information declaration,but jacoco didn't work here,but it works in the java project with the same configuration. 
    jacoco {
        toolVersion = "0.6.2.201302030002"
        reportsDir = file("$buildDir/customJacocoReportDir")
    }


    //Define android build information
    android {
        compileSdkVersion 18
        buildToolsVersion "18.1.1"

        sourceSets {
            main {
                manifest.srcFile 'AndroidManifest.xml'
                java.srcDirs = ['src']
                resources.srcDirs = ['src']
                aidl.srcDirs = ['src']
                renderscript.srcDirs = ['src']
                res.srcDirs = ['res']
                assets.srcDirs = ['assets']
            }

             //Set the build path,the root folder
            instrumentTest.setRoot('../TVEAndroidTest')

            //Set the code and resuource path for build
            instrumentTest {
                java { srcDirs = [
                       '../TVEAndroidTest/src/'
                   ] }
              res.srcDirs = ['res']
               assets.srcDirs = [
                    '../TVEAndroidTest/assets'
               ]
                resources.srcDirs = [
                    '../TVEAndroidTest/src'
                ]

            }


            //Define the package name for build
            defaultConfig {
                testPackageName "com.accedo.android.tve.test"
                testInstrumentationRunner "android.test.InstrumentationTestRunner"
            }

            // Move the build types to build-types/<type>
            // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
            // This moves them out of them default location under src/<type>/... which would
            // conflict with src/ being used by the main source set.
            // Adding new build types or product flavors should be accompanied
            // by a similar customization.
            debug.setRoot('build-types/debug')
            release.setRoot('build-types/release')
        }
    }

    jacoco {
        append = false
        destinationFile = file("$buildDir/jacoco/jacocoTest.exec")
        classDumpFile = file("$buildDir/jacoco/classpathdumps")
    }

    //PMD task
    task pmd(type: Pmd) {
        ruleSetFiles = files('../config/quality/pmd/pmd-ruleset.xml')
        ruleSets = ["basic", "braces", "strings"]
        source = android.sourceSets.main.java.srcDirs
    }

    //CheckStyle task
    task checkstyle(type: Checkstyle) {
        configFile file('../config/quality/checkstyle/checkstyle.xml')  
        source android.sourceSets.main.java.srcDirs
        include '**/*.java'
        exclude '**/gen/**'

        classpath = files( project.configurations.compile.asPath )
    }

    //Findbugs task
    task findbugs(type: FindBugs) {

        excludeFilter file('../config/quality/findbugs/findbugs-filter.xml')
        classes = fileTree('build/classes/debug')
        source = android.sourceSets.main.java.srcDirs
        classpath = files( project.configurations.compile.asPath )

        reports {
            xml {
                destination "build/reports/findbugs/findbugs.xml"
            }
        }

        effort = 'max'
    }

    jacocoTestReport {
        reports {
        xml.enabled false
        csv.enabled false
        html.destination "${buildDir}/jacocoHtml"
        }
    }

}

当前的问题是“找不到方法 jacocoTestReport() ...balabala”

任何建议将不胜感激!

jacoco 插件与 Android 不兼容。要获得 jacoco 报告，您需要自行检测您的类(class)。为此，请将其添加到您的 gradle 构建配置文件中:

configurations {
   codeCoverage
   codeCoverageAnt
}
dependencies {
   codeCoverage 'org.jacoco:org.jacoco.agent:0.5.10.201208310627:runtime@jar'
   codeCoverageAnt 'org.jacoco:org.jacoco.ant:0.5.10.201208310627'
}

tasks.whenTaskAdded { task ->
    if (task.name == 'testDefaultFlavorDebug') { /* Name of your test task */
       task.jvmArgs "-javaagent:${configurations.codeCoverage.asPath}=destfile=${project.buildDir.path}/coverage-results/jacoco.exec,sessionid=HSServ,append=false",
            '-Djacoco=true',
            '-Xms128m',
            '-Xmx512m',
            '-XX:MaxPermSize=128m'
    }
}

运行测试后，“build/coverage-results”目录中将有一个 jacoco.exec 文件
