How to exclude some pakages from code coverage report using android and jacoco

Question

I try to exclude some packages from the jacoco report but I don't find any documentation about doing that.

I tried that, but doesn't work:

testOptions {
    unitTests {
        jacoco {
            afterEvaluate {
                classDirectories.setFrom(files(classDirectories.files.collect {
                    fileTree(dir: it, exclude: '**/*databinding/**/*.*')
                }))
            }
        }
    }
}

I use com.android.tools.build:gradle:8.0.2 and org.jacoco:org.jacoco.core:0.8.8.

Do you know how to exclude packages from jacoco report?

I don't find any "packaged" solution to solve my issue, so to move forward, I create my own gradle task:

task jacocoDebugUnitTestCoverageReport(type: JacocoReport, dependsOn: ['testDebugUnitTest']) {
    group = "Verification"
    description = "Creates JaCoCo test coverage report"
    reports {
        html.required = true
        xml.required = true
    }
    classDirectories.from = fileTree(
            dir: "$buildDir/intermediates/classes/debug/transformDebugClassesWithAsm/dirs/my/package/app",
            excludes: [
                    '**/databinding/*',
                    '**/Dagger*',
                    '**/Hilt*',
                    '**/DataBinding*',
                    '**/DataBinder*',
                    '**/*_*'
            ]
    )
    sourceDirectories.from = ['src/main/java/my.package.app']
    executionData.from = fileTree(
            dir: "$buildDir",
            includes: ["outputs/unit_test_code_coverage/debugUnitTest/testDebugUnitTest.exec"])
}

Running ./gradlew jacocoDebugUnitTestCoverageReport generate a coverage report without excluded packages.

If you know a better solution, I would appreciate your sharing.
