How to make “sourceDirectories” public in Jacoco report generation?

问题

I was following this post to setup Jacoco code coverage for my project.

But I am facing a error while writing the task to generate the report.

Gradle Task

task jacocoTestReport(type: JacocoReport, dependsOn: ['testDebugUnitTest', 'createDebugCoverageReport']) {

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

    def fileFilter = ['**/R.class', '**/R$*.class', '**/BuildConfig.*', '**/Manifest*.*', '**/*Test*.*', 'android/**/*.*']
    def debugTree = fileTree(dir: "$project.buildDir/intermediates/javac/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/debugAndroidTest/connected/**/*.ec'
    ])
}

The error I am getting is :

Cannot set the value of read-only property 'sourceDirectories' for task ':app:jacocoTestReport' of type org.gradle.testing.jacoco.tasks.JacocoReport.

Below field's are private in the jacoco now I believe.

• sourceDirectories
• classDirectories
• executionData

My dependency : classpath "org.jacoco:org.jacoco.core:0.8.4"

Also, I tried to change the version but no help.

Found the Answer here

task jacocoTestReport(type: JacocoReport, dependsOn: ['testDebugUnitTest', 'createDebugCoverageReport']) {

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

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

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

(sourceDirectories =) in not allowed in latest gradle version instead (sourceDirectories.from) should be used .
