Package doesn't exist error in intelliJ

Question

I\'m trying to use the barbecue barcode printing library. I have successfully added the library to IntelliJ through project structure add library. Then I imported the packa

Answer 1

I tried

1. "Maven > Reimport"
2. Deleting the .idea directory, and reopening the project.
3. File -> Invalidate Caches/Restart then Build -> Rebuild Project
4. Deleting what is inside local .m2 folder, and downloading dependencies again.
5. Running mvn idea:idea in Maven console (Though this command is obsolete, I had to try.)

in different combinations.

But going from Intellij 2020 version to 2019 solved my issue.
