not possible to generate Option[List[Foo]] or empty list

[rkazanova]

there is not possible to generate Option[List[Foo]] or empty list

somearray:
   type: array
   items:
      $ref: "#/components/schemas/Foo"

We can use property for this feature:
nullable: true => for Option[List[Foo]] // to generate Option[List[Foo]]
default: [] => for empty list // to generate empty list

for the first proposal I added CustomMapping and it works:

.addMapping(CustomMapping.forField({
    case Field(prop, annot, typeDef) if prop.nullable & prop.`type`.isCollection =>
      Field(prop, annot, typeDef = TypeDef(s"Option[${typeDef.name}]", Imports.empty))
  }))

it means that

locations:
   type: array
   items:
     $ref: "#/components/schemas/Location"
   nullable: true

generates field in case class as Option[List[Location]]

Sorry for the delay. That is a bug then, it should be an Option if the property is not mentioned in the list of required. Thank you for the good workaround! I assume that your workaround also works without the nullable: true property (only omit it from the required list)?

Without nullable my solution doesn't work. BTW. I don't have this collection in required.

Thanks for the update! Hm, seems like arrays are handled a bit differently. I think your workaround could be applied by the plugin automatically whenever nullable: true is defined.
