Junit test in IntelliJ IDE can't see class for testing

I created simple Java project in IntelliJ, one class (RandomizedQueue) and generated JUnit test class for it. So it's just two files and they both are in the same directory - src.

Everything compiled and all was well. For some time. Then suddenly - it stopped with this error:

java: cannot find symbol
  symbol:   class RandomizedQueue
  location: class RandomizedQueueTest

I tried everything I could think of. Recreating a project worked for a while but the same error reappeared (without any obvious reason). I can't find any logic in this! Compilation from cmd does work.

I tried deleting everything from class and test - and I still can't make an instance in test method.

here is the whole project

I had the same problem. I fixed it by rebuilding the package in which the tests were located. Right click on the package and select "rebuild 'package name'".

I have the same issue every once in a while in my gradle projects (I'm on IntelliJ 2018.2.4 now).

The solution is to open a terminal and execute gradlew idea.

See those white x-es next to the class name?

Somehow you have excluded RandomizedQueue class from the compilation.

Remove it from the excludes and everything will be back to where it was before.
