Question

我似乎对Android Studio似乎无法正确解决依赖关系感到非常恼火。我会遇到各种错误，但通常标志是出问题的是导入语句用红色突出显示，例如

通常这是无害的，只会影响代码完成和符号导航。该应用程序将构建并运行良好。但是，对于单元测试，这似乎确实存在问题，因为它们无法运行。例如，我目前看到的是

这里似乎没有一致的行为。不导入的软件包会有所不同。

请注意，我的同事可以运行测试和编译，并且该项目以CI运行，所以我很确定该项目定义正确。

我没有解决问题的好方法。我已经尝试了以下所有内容的组合和排列

已更新：Gradle同步
使缓存无效
清洁项目
已关闭的项目
手动删除项目中的文件（包括删除所有不必要的IDE文件）
已删除$SOURCE/.gradle
已删除~/.gradle

似乎没有任何效果（一致地）。我目前不知道如何在不花费大量时间深入研究Android Studio和gradle的情况下诊断问题。

有人对此有见识或明确的解决方案吗？

Android Studio经常抱怨缺少依赖项（突出显示为红色）。单元测试也失败
