Unable to customize Jackson ObjectMapper

[viniciusccarvalho]

Hi there, I'm trying to use the library with Kotlin, and I'm reading some CRDs that I have defined, but because the WatchHTTPManager class creates a mapper without allowing customization:

kubernetes-client/kubernetes-client/src/main/java/io/fabric8/kubernetes/client/dsl/internal/WatchHTTPManager.java

Line 51 in 79132f3

private static final ObjectMapper mapper = new ObjectMapper();

I can't create add a module to jackson object mapper. Is there a way around this? Adding custom modules on jackson may be required for other usages besides kotlin

Regards

@viniciusccarvalho damn.. I am stuck with this one as well. We might better provide a PR to fix it and hope for a release :)

probably WatchHTTPManager class should be initializing the mapper field by calling Serialization.jsonMapper(), because that one can be easily customized by something like:

Serialization.jsonMapper().configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, 
false);

Also faced with issue when trying to deserialize Scala case classes

thanks to @jkremser, I am able to customize mapper like this:

Serialization.jsonMapper().registerModule(DefaultScalaModule)

This should no longer be an issue after #1963
WatchHTTPManager now uses Serialization class

Following should work now:

Serialization.jsonMapper().configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, 
false);
