How to refer to generated source files?

Question

How do I refer to files generated by a sourceGenerators sbt task? I know that the source file is deposited to target/scala-<version>/src_managed/path/to/File.Scala but I don't know how to reference it in my project. Any ideas?

/server
  /app
    /models
      Driver.scala (can't use MyGeneratedCode here)
  /project
    /src/main/scala/
      ModelGenerator.scala  (the code used to create MyGeneratedCode.scala)
    /target/scala-2.12
      /classes
      /src_managed
        /main/generated/
          MyGeneratedCode.scala

You probably do not want to refer to the file itself, but to classes / objects / traits in them. If so, just as normal import them from their package and use them. What is the problem? — Luis Miguel Mejía Suárez, Apr 29 '19 at 20:02
Can't figure out how to import the package... *nervous grin* — franklin, Apr 29 '19 at 20:07

The generate file works as any normal Scala file but on a fancy folder so it is not tracked by git (or any other VCS).
As any Scala file, it should had a package whatever statement at the beginning, from which you can latter import your classes (import whatever._). Usually the package name matches the directory structure, but they do not have to (specially since it is just generated file).

If it does not have a package, all its members probably resides on the __root__ package. But that probably would cause troubles, I would suggest editing your generator to add a package statement instead.

Perfect. Adding the `package` line is what helped! – franklin May 28 '19 at 02:05 — franklin, May 28 '19 at 02:05
