Description

Please see my comment below.

Generating from IntelliJ using the following configuration leads to unexpected Gson code to be in the generated result.

I think you forgot the following conditions:
{{#generateOneOfAnyOfWrappers}}
{{#gson}}

in these files:
modules/openapi-generator/src/main/resources/kotlin-client/anyof_class.mustache
modules/openapi-generator/src/main/resources/kotlin-client/oneof_class.mustache

Before you generate the Gson based TypeAdapter.

What do you think??
