安卓+ JaCoCo：jacocoTestCoverageVerification 永远不会失败

Question

我正在尝试配置一个新的 Android 项目以使用 JaCoCo 进行测试覆盖率，但当覆盖率低于某个阈值时会失败。我使用过 此文档，并查看了许多 SO 帖子。我预计任务会失败，因为我没有测试覆盖率，但它成功了，没有任何警告。

我的 :app build.gradle 文件包含以下内容：

plugins {
    ...
    id 'jacoco'
}

jacoco {
    toolVersion = "0.8.7"
    reportsDirectory = layout.buildDirectory.dir('app/build/reports')
}

task jacocoTestCoverageVerification(type: JacocoCoverageVerification, dependsOn: ['jacocoTestReport']) {
    onlyIf = { true }
    violationRules {
        failOnViolation = true
        rule {
            limit {
                minimum = 1.0
            }
        }
    }
}

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

    onlyIf = {true}
    reports {
        xml.enabled  true
        html.enabled  true
        html.outputLocation = layout.buildDirectory.dir('app/build/reports')
    }


}

tasks.withType(Test) {
    finalizedBy jacocoTestReport

    jacoco.includeNoLocationClasses = true
    jacoco.excludes = ['jdk.internal.*']
}

android {
    ...
    jacoco{
        version  = "0.8.7"
    }
}

当我尝试运行测试时，使用以下任何一项：

./gradlew test
./gradlew jacocoTestReport
./gradlew jacocoTestCoverageVerification

结果始终相同：

...

Starting 2 tests on Nexus 5X - 8.1.0

> Task :app:createDebugAndroidTestCoverageReport
> Task :app:createDebugCoverageReport
> Task :app:jacocoTestReport
> Task :app:jacocoTestCoverageVerification

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

我预计任务会失败，因为我没有测试覆盖率。我添加了一个实用程序类和方法，并部分实现了一个测试，以便 JaCoCo 报告显示一个类的覆盖率为 60%，但这并没有改变任何东西。
