-------------------------------
Resolution: Not A Problem
> add jackson-module-kotlin to Jackson packages that get shaded
> -------------------------------------------------------------
>
> Key: FLINK-32237
> URL: https://issues.apache.org/jira/browse/FLINK-32237
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.17.1
> Reporter: Samael Bate
> Priority: Major
>
> Because of the shaded Jackson packages having their package names prefixed,
> such as
> {_}org.apache.flink.shaded.jackson2.com.fasterxml.jackson.databind.json.JsonMapper{_},
> when writing a Flink project in Kotlin I am unable to register the
> _KotlinModule_ or use {_}jacksonObjectMapper(){_}.
>
> It would be great if these classes were repackaged using the same using the
> same _org.apache.flink.shaded.jackson2.*_ prefix:
> {code:java}
> import com.fasterxml.jackson.module.kotlin.KotlinModule
> import com.fasterxml.jackson.module.kotlin.jacksonMapperBuilder
> import com.fasterxml.jackson.module.kotlin.jacksonObjectMapper {code}
>
> Due to the mismatch in package names I can do neither of the following:
> {code:java}
> val jsonMapper = jacksonMapperBuilder()
> .addModule(JavaTimeModule())
> .build() {code}
> or
> {code:java}
> val jsonMapper = JsonMapper()
> .registerModule(KotlinModule()) {code}
> the Kotlin module inherits from {{com.fasterxml.jackson.databind.Module}} and
> the re-packaged ones are inheriting from
> {{{}[org.apache.flink.shaded.jackson2.com|http://org.apache.flink.shaded.jackson2.com/]{}}}{{{}.fasterxml.jackson.databind.Module{}}}.
>
> For now I can work around this with a wrapper class but it would be nice to
> have this available out of the box.
