I'm taking an online course and was instructed to import a set of exercises into IDEA as a project. I'm unable to run the classes after building and rebuilding the project. There's a separate getting started course which show's you how to do all of this and it works fine, so I'm not sure what's wrong.
The getting started project works fine
I've compared the build.project files and I see errors: Errors in the main project for the course
I get a message about a problem that I haven't been able to resolve when I run
sbt sbtVersion
in my project directory:
PS M:\School\Scala Applied Part 1> cd .\exercises-applied\

I can't seem to find

In the file structure and I don't know how to update it.
CodePudding user response：
build.sbt needs to bee in the root directory. I've changed the root directory of the project and it builds fine. Thanks Mateusz!
