但是当我访问index.html时，它看起来是这样的：

两件事

要修复第一个错误“由于“java.lang.VerifyError”导致检测运行失败”，请将构建工具升级到21+。这是他们已经修复的android构建工具中的一个bug。万岁

你不必应用jacoco插件，它是android gradle插件的一部分。您所需要的只是“testCoverageEnabled true”，它将创建您的.ec文件。据我所知，应用这个插件并没有什么坏处，但是让你的头脑了解jacoco已经在那里了这一事实是很有帮助的

---

“reportsDir”的覆盖可能不起作用，因此您还应该在“build/outputs/reports/coverage/debug/index.html”中查找报表。

应用插件部分会导致测试无法运行。 正如Bill所说，gradle的最新版本中包含了jacoco，因此无需再应用它

我的考试因此而中断。 删除该行修复了我的问题，我再次收到报告
