我正在尝试使用jacoco来生成代码覆盖率.但是,当我运行命令./gradlew任务时,我没有看到任何名为jacocoTestReport的任务.

当我尝试运行任务时出现以下错误./gradlew jacocoTestReport：

Task ‘jacocoTestReport’ not found in root project ‘EnumSample’

这是我的build.gradlew文件：

apply plugin: 'com.android.application'
apply plugin: 'jacoco'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "me.androidBox.enumsample"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
        }
        debug {
            testCoverageEnabled true
        }
    }
}

jacoco {
    toolVersion "0.8.0"
}

task jacocoTestReport(type: JacocoReport) {
    executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")

    subprojects.each {
        sourceSets it.sourceSets.main
    }

    reports {
        xml.enabled true
        html.enabled false
        csv.enabled false
    }
}

dependencies {
    implementation fileTree(dir: 'libs',include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.0.2'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

我试图清理并重建项目.但是,报告任务不存在.

非常感谢任何建议.
