Description

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

The first I've already reported here: https://github.com/OpenAPITools/openapi-generator/issues/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.

Start with the scala-akka generator using the linked Argo Workflows OpenAPI declaration, then inspect generated EnumsSerializers.scala alongside the generated model Any. Reproduce with mvn clean install; done means the generated Scala client compiles without the Any name collision.
