那些遇到过的问题

Kotlin JaCoCo，没有覆盖 -> IllegalClassFormatException ...请提供原始的非检测类

gol*_*992 12 android code-coverage gradle jacoco kotlin

科特林版本： 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：2 种风格：完整、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 library]（在测试覆盖范围内按预期工作）
  • client-test-support（用于活动的测试实现）
  • 客户端 [android 库]（无覆盖）-> 取决于公共资源，客户端测试支持
  • service-test-support（用于活动的测试实现）
  • 服务 [android 库]（无覆盖）-> 取决于公共资源，服务测试支持
  • 应用程序 [android 应用程序] 没有测试

对于这篇文章的上下文，我只对单元测试感兴趣

测试按预期运行，但是由于某些（不是全部）kotlin 编译类被识别为“检测类”，因此没有生成覆盖率

错误出现在测试即将进行时，许多类都打印出以下内容：

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 我可以确认似乎IllegalClassFormatException没有覆盖和没有覆盖之间的联系。因此我将更新问题成为以下

更新 2： 在对更新 1 进行进一步试验后，似乎异常消失并且覆盖率按预期计算，当不依赖于子（测试）模块时，即testApi project(":client:testsupport")从 gradle 文件中删除该行。问题是我需要这个testsupport模块来执行我的活动测试（这些测试目前没有运行，因为它们位于更新 1 ^^ 的 .old 文件中。

根据 udate 2 更新的问题 如何按照 robolectric 团队在此拉取请求中的建议，配置 JaCoCo 以支持 android 类的子模块测试实现。

如果需要更多信息，将更新帖子

感谢@Paulo Costa提供问题链接

对我来说，这是通过添加解决的

    plugins {
        id 'com.android.library'
        id 'jacoco'
    }
    //these lines
    tasks.withType(Test.class).configureEach {
        jacoco {
            excludes = ["*"]

我刚刚遇到了同样的错误。

经过一番调查，似乎是Android Gradle Plugin中的一个错误，只有在使用com.android.library.

我在这里报告了它和更多细节：https : //issuetracker.google.com/issues/178015739

虽然它不是由 Android 团队修复的，但解决方法是配置

jacoco {
    toolVersion = "0.7.9"
}
Run Code Online (Sandbox Code Playgroud)

在 build.gradle 中

它不会阻止错误被记录下来，而是可以正确收集覆盖率数据。
