Description

Generating a scala-akka client for Argo Workflows, I encounter a couple issues.

The first I've already reported here: #5580

After replacing all three instances of ByteArray with Array[Byte], I try mvn clean install again.

I get the following error:

[ERROR] /home/.../src/argo-client-scala/src/main/scala/org/openapitools/client/api/EnumsSerializers.scala:44: error: overriding method serialize in trait Serializer of type (implicit format: org.json4s.Formats)PartialFunction[Any,org.json4s.JValue];
[ERROR]  method serialize has incompatible type
[ERROR]     def serialize(implicit format: Formats): PartialFunction[Any, JValue] = {

This happens because Any in EnumsSerializers.scala refers to the generated org.openapitools.client.model.Any. If I change the name of that case class to ArgoAny and update all references besides the one in EnumsSerializers.scala, the build error goes away.

Looks as if Any just isn't treated as a reserved keywork in scala-akka and should be. But I'm not certain.

Another possible fix to avoid the name collision is to use the fully qualified scala.Any name in EnumsSerializers.scala
def serialize(implicit format: Formats): PartialFunction[scala.Any, JValue]

File-level namespace imports of generated stuff opens up the possibility for such name collisions.
