Error running dso-demo pipeline : No httpclient implementations found

freddysf

Happy New Year all:-)
Following the "Launching a Simple DevOps Pipeline" instructions, forked dso-demo and created pipeline in Jenkins, the pipeline fails with the following error:

_Obtained build-agent.yaml from 948030e99d7f6e5de79a9355fe3948474e6c747c

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

Running with GKE 3 node cluster k8s version 1.25.4-gke.2100

FYI Upgraded the Kubernetes plugin to https://github.com/jenkinsci/kubernetes-plugin/releases/tag/3802.vb_b_600831fcb_3 and it works now

@freddysf, I would attempt to recreate this issue and update with the same instructions.

Thanks Gourav. FYI I've tried downgrading the Kubernetes plugins as per https://issues.jenkins.io/browse/JENKINS-70392?filter=-4 but doesn't help. Please DM me if you need to access my jenkins instance.

Hi Gourav, I am facing the same error. Is there any update on this?
