I would like to use JsonContentPolymorphicSerializer
to dynamically deserialize field of JSON. Deserialization is working great, but when I try to serialize object into JSON, following exception is thrown:
java.lang.NoClassDefFoundError: kotlin/uuid/Uuid
Below is minimal code to reproduce error. I guess there could be a problem in my pom.xml but I have no idea how to find where that mistake is.
fun main() {
println(Json.encodeToString(Company("Company 1", "basic")))
}
object PlanSerializer2 : JsonContentPolymorphicSerializer<String>(String::class) {
override fun selectDeserializer(element: JsonElement) = String.serializer()
}
@Serializable
data class Company(
val name: String,
@Serializable(with = PlanSerializer2::class)
val plan: String
)
My pom.xml
