android - Kotlin JaCoCo，无覆盖 -> IllegalClassFormatException ...请提供原始的非仪器类

Question

kotlin 版本: 1.3.61

Android Gradle 插件: 3.5.3

JaCoCo 版本: 0.8.4.201905082037(默认android gradle版本)

项目:
https://github.com/goldy1992/Mp3Player/tree/feature/issue-112/migrate-to-kotlin

我有一个 多模块 gradle 项目 和:
2种口味:全，自动化
2 种构建类型:发布、调试

我正在将所有内容迁移到 kotlin。

模块结构

commons [android 库](按预期工作，测试覆盖率)

客户端测试支持(用于测试 Activity 的实现)

客户端 [android 库](无覆盖)-> 依赖于 commons，client-test-support

service-test-support(用于 Activity 的测试实现)

服务 [android 库](无覆盖)-> 依赖于 commons，service-test-support

app [android 应用] 没有测试

对于这篇文章的上下文，我只对 感兴趣单元测试

测试按预期运行，但是由于部分(不是全部)kotlin 编译的类被识别为“仪表类”，因此没有生成覆盖率

这些错误出现在测试即将成为许多类的以下打印输出的地方:

    java.lang.instrument.IllegalClassFormatException: Error while instrumenting com/github/goldy1992/mp3player/client/views/viewholders/MediaPlayerTrackViewHolder.

为了尝试找到问题的根源，我只运行了 客户端单元测试

客户 build.gradle

}

 /* MORE DEPENDENCIES NOT RELEVANT TO ISSUE */
}

值得注意的是，我使用的是 Dagger 2.25.2

执行数据目录 : ${projectRootDir}/client/build/jacoco/testFullDebugUnitTest.exec

源目录 : ${projectRootDir}/client/src/main/java

类(class)目录 : ${projectRootDir}/client/build/intermediates/javac/fullDebug/classes/, ${projectRootDir}/client/build/tmp/kotlin-classes/fullDebug/

更新 1:
从创建一个新分支并将客户端模块中的所有类和测试类重命名为 CLASS_NAME.kt.old 我可以确认 IllegalClassFormatException 之间似乎没有任何联系并且没有覆盖。因此，我将问题更新为以下

更新 2:
在对更新 1 进行进一步试验后，似乎异常消失了，并且覆盖率按预期计算当不依赖子(测试)模块时，即删除行 testApi project(":client:testsupport")从 gradle 文件。问题是我需要这个 testsupport模块以执行我的 Activity 测试(当前未运行，因为它们在 .old 文件中，根据更新 1 ^^。

根据 udate 2 更新的问题
如何配置 JaCoCo 以支持 android 类的子模块测试实现，如 robolectric 团队在 this pull request 中所建议的那样.

如果需要更多信息，将更新帖子

Answer 1

我刚刚遇到了同样的错误。
经过一番调查，这似乎是Android Gradle插件中的一个错误，并且仅在使用com.android.library时发生.
我在这里报告了它和更多细节:https://issuetracker.google.com/issues/178015739
虽然 Android 团队没有修复它，但解决方法是配置

jacoco {
    toolVersion = "0.7.9"
}

在 build.gradle
它不会阻止错误被记录，但可以正确收集覆盖数据。
