Hello,

Before the new Kubernetes api, we were using the plugins to do the following :

import io.fabric8.kubernetes.api.model.ListOptionsBuilder
import io.fabric8.kubernetes.client.DefaultKubernetesClient;
import io.fabric8.kubernetes.client.KubernetesClient;

KubernetesClient client = new DefaultKubernetesClient();

def ns = client.namespaces()
        .list()

Directly in our Groovy script with the following setup :

Jenkins-2.381
Kubernetes 3734.v562b_b_a_627ea_c
Kubernetes Client API 5.12.2-193.v26a_6078f65a_9
Kubernetes Credentials 0.9.0

With the new api, it doesn't seems to be possible anymore. Wy tried to do the following :

import io.fabric8.kubernetes.api.model.ListOptionsBuilder
import io.fabric8.kubernetes.client.KubernetesClient;
import io.fabric8.kubernetes.client.KubernetesClientBuilder;

KubernetesClient client = new KubernetesClientBuilder().build();

With :

Jenkins-2.385
Kubernetes 3834.vdc85747145e6
Kubernetes Client API 6.3.1-206.v76d3b_6b_14db_b
Kubernetes Credentials 0.10.0

But we got the following error :

io.fabric8.kubernetes.client.KubernetesClientException: No httpclient implementations found on the context classloader, please ensure your classpath includes an implementation jar

Do you have any hint about this error ? Do we miss something to configure with the new kubernetes API ?

Thank you for your help
