(I know it's more a Jackson than a Kotlin question, but I hope someone might have an answer anyway). I have a line `val jackson: YAMLMapper = YAMLMapper.builder().addModule(KotlinModule()).build()`in my code to create a Jackson YAML mapper with Kotlin extensions. This tells me "Kotlin: 'constructor KotlinModule(Int = ..., Boolean = ..., Boolean = ..., Boolean = ..., SingletonSupport = ..., Boolean = ...)' is deprecated. Use KotlinModule.Builder instead of named constructor parameters". Does that really mean I should use `val jackson: YAMLMapper = YAMLMapper.builder().addModule(KotlinModule.Builder().build()).build()`instead? That's an awful amount of build...

use

kotlinModule { }

and how do I get the YAML mapper into that?

An alternative way is to use:

val jackson = ObjectMapper(YAMLFactory()).registerKotlinModule()

that will result in an

ObjectMapper

and not a

YAMLMapper

but should be ok for me because I don't think I need any YAMLMapper-specific APIs.

Yeah, in most cases you shouldn't

kotlinModule { ... }

replaces

KotlinModule.Builder(). ... .build()

, so you should see how to use that with

YAMLMapper.builder()

right. So I have 2 options which seems equally good:

ObjectMapper(YAMLFactory()).registerKotlinModule()

and

YAMLMapper.builder().addModule(kotlinModule()).build()

. Thanks for your help!
