Printer class not recognized by PrinterTest

Hey all,

I'm getting exceptions in the provided code that suggest the Printer class is not being recognized by the PrinterTest class. I'm a little out of practice with Java... I haven't changed anything about the provided file structure in the project. Is there something obvious that I'm missing?


Error:(31, 39) java: cannot find symbol
  symbol:   class Printer
  location: class com.teamtreehouse.challenges.PrinterTest
Error:(53, 5) java: cannot find symbol
  symbol:   variable Printer
  location: class com.teamtreehouse.challenges.PrinterTest
Error:(54, 5) java: cannot find symbol
  symbol:   variable Printer
  location: class com.teamtreehouse.challenges.PrinterTest

Thank you for your time!

Actually, I think I just got it! Maybe a quirk between versions of IntelliJ, but...

When importing the project, the default import options contain:

  • [ ] Use Auto Import (default for me: OFF)
  • [ ] Create directories for empty content roots automatically (default for me: OFF)
  • [ ] Create separate module per set (default for me: ON)

When i imported the file with ON, ON, OFF above, I no longer encountered the issue. I know it's not a very technical solution, but trial and error won out! Testing multiple configurations points to "Create separate module per set" being the root of the issue; with that disabled, the issue is no longer present.

Steps for IntelliJ:

  1. Download project from treehouse quiz
  2. Unzip project
  3. Within IntelliJ, select File > Open > select your project folder
  4. The Import Project from Gradle pane should pop up without manual selection, then within the pane:
  • DISABLE "Create separate module per source set" (critical) ***from my tests, this is the primary source of the issue
  • Enable "Use auto-import" (optional)
  • Enable "Create directories for empty content roots automatically" (optional)
  • Hit OK and you should be able to build your project as provided without exceptions

Can you explain a little more in detail what you did? I'm having the same issue. It's driving me crazy. I'm on the auto import settings but I don't see any of the options you mentioned above.

UPDATE, I found what you meant "Import Gradle Project" however even after I did that I'm still getting that error with printer test class.

Hey Daniel, do the steps to reproduce help?
