如何在Android和gradle上使用Jacoco生成覆盖率报告时排除测试

buildscript {
    dependencies {
        classpath 'org.jacoco:org.jacoco.core:0.8.7'
    }
}

apply plugin: 'jacoco'

android {
    // ...
}

jacoco {
    toolVersion = "0.8.7"
}

task jacocoTestReport(type: JacocoReport, dependsOn: ['testDebugUnitTest', 'createDebugCoverageReport']) {
    reports {
        xml.enabled = true
        html.enabled = true
    }

    def fileFilter = ['**/R.class', '**/R$*.class', '**/BuildConfig.*', '**/Manifest*.*', '**/*Test*.*', 'android/**/*.*']
    def debugTree = fileTree(dir: "${buildDir}/intermediates/classes/debug", excludes: fileFilter)
    def mainSrc = "${project.projectDir}/src/main/java"

    sourceDirectories = files([mainSrc])
    classDirectories = files([debugTree])
    executionData = fileTree(dir: project.buildDir, includes: ['jacoco/testDebugUnitTest.exec', 'outputs/code-coverage/connected/*coverage.ec'])
}

./gradlew jacocoTestReport
