Android 本地单元测试通过，但编辑器窗口“无法解析符号”

Question

Android Studio 的编辑器抱怨它无法解析单元测试中的符号，尽管

main/

和

test/

中的目录结构匹配正确。

尽管如此，测试还是会通过...

我已经使缓存失效并重新启动，并在

~/.gradle

中清除了我的 Gradle 缓存，但我只希望前者会对编辑器窗口产生任何影响，因为 - 就像我说的 - 测试 does 通过.

这个问题只有在我删除文件夹结构中不需要的层时才会出现：

agent2/app/src

成为

agent2/src

并且没有对任何

app

文件夹的引用

（显然这是对真实项目的简化）

文件结构

top-level-project
  agent2/
    src/
      main/
        com/
          level1/
            Class1.java
            level2/
              Class2.java
      test/
        com/
          level1/
            Class1Test.java

agent2 build.gradle

顶层build.gradle
