kotlin verion: 1.3.61
安卓Gradle插件： 3.5.3
JaCoCo版本： 0.8.4.201905082037 (默认安卓级版本)
项目：https://github.com/goldy1992/Mp3Player/tree/feature/issue-112/migrate-to-kotlin
我有一个多模块级项目，有:2种口味:完全自动化2种构建类型:发布、调试
我正在把所有的东西都迁移到kotlin。
模块结构
- 公域android库
- 客户端-测试支持(用于活动的测试实现)
- client android库 ->依赖于共享，客户端测试支持。
- 服务.测试.支持(用于活动的测试实现)
- 服务android库 ->依赖于公共资源，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
然而，由于一些(并非全部) kotlin编译类被确认为“工具化类”，所以测试按预期运行，因此不会产生覆盖范围。
出现这些错误时，许多类的测试即将打印如下内容：

更新1:从创建一个新分支到将客户端模块中的所有类和测试类重命名为CLASS_NAME.kt.old，我可以确认在IllegalClassFormatException和no覆盖之间似乎没有任何联系。
更新2:在进一步试验更新1之后，当不依赖子(test)模块(即从gradle文件中移除行testApi project(":client:testsupport"))时，异常似乎消失了，覆盖率按预期计算。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，因为它们在.old文件中，如更新1 ^^所示)。
问题按udate 2更新，如何配置JaCoCo以支持此拉请求中的机器人类的子模块测试实现。

我只是面对着同样的问题。
经过一番调查，它似乎是安卓Gradle插件中的一个bug，只有在使用com.android.library时才会发生。
我已经在这里报告了它和更多的细节：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中
它并不阻止错误被记录，而是使它能够正确地收集覆盖率数据。

感谢@Paulo Costa发布链接
对我来说，这是通过增加
plugins {
id 'com.android.library'
id 'jacoco'
}
//these lines
tasks.withType(Test.class).configureEach {
jacoco {
excludes = ["*"]
}
}贷记：https://issuetracker.google.com/issues/178015739#comment6
