Magnolia interface unification for Scala 2 and Scala 3 versions

[YaroslavSagach]

In a process of migrating the project to Scala 3, I created a cross build. In which, I separated code with magnolia, that differs. So the Scala 2. code uses 1.1.3 version, and Scala 3 uses 1.2.6. Also, there is common code, which I want to keep for both versions. But, I've stumbled upon a problem, that those 2 versions of magnolia have different interfaces. In particular, I have a problem with CaseClass 'params'. In 1.1.3 it's "parameters", but in 1.2.6 it's "params" :

magnolia/src/core/interface.scala

Line 109 in 27d0e67

val params: IArray[CaseClass.Param[Typeclass, Type]],

magnolia/core/src/main/scala/magnolia1/interface.scala

Line 546 in 2a2ecb8

override def parameters: Seq[Param[Typeclass, Type]] = parametersArray

So, is there any way to unify these interfaces, for such use cases like mine?

Yes, and I expect this might diverge further. For example, we'll be releasing magnolia 2 for scala 3 using a different package name (see #457), and there might be more changes needed to support scala3-specific types. So I don't think having a unified interface will be possible in the long run.
