io.kubernetes.client.openapi.models.V1Deployment Class not found exception

[kellycampbell]

This seems to have started after a kubernetes 1.16 -> 1.17 cluster upgrade. We don't have a lot of jobs using this cd plugin yet, so we didn't notice right away.

19:14:55  ERROR: ERROR: Can't construct a java object for tag:yaml.org,2002:io.kubernetes.client.openapi.models.V1Deployment; exception=Class not found: io.kubernetes.client.openapi.models.V1Deployment

The class file exists, and there doesn't seem to be another plugin which has an older version of the kubernetes client jar.

I have the same problem running Kubernetes v1.18.3. I'm running Jenkins v2.235.1 and all my plugins are up to date.

The workaround I've found for now is to downgrade Jackson 2 API to v2.10.3 and to downgrade Snakeyaml API to v1.26.2. If those 2 plugins are updated to their respective latest versions, the error message comes back.

It worked for me too, I downgraded manually those plugins versions and the pipeline run successfully!

Thanks!

[Danepic]

Any another workaround?

[eliskvitka]

Downgrading plugins worked for me too. I'm running clean Jenkins v2.254 with recommended plugins and latest Kubernetes Continuous Deploy Plugin (2.3.0) and have same error. After downgrading:

• Jackson 2 API 2.11.2 -> 2.10.3
• Snakeyaml API 1.26.4 -> 1.26.3
• Kubernetes Client API 4.9.2-2 -> 4.9.2-1
• Kubernetes Credentials 0.7.0 -> 0.6.2

all works fine! Also, i downgraded ECharts API and JUnit, but this plugins not required for kubernetes cd. Thanks

[bill23-kim]

this issue been resolved? in 2.1.2 version change log, it is written as below.

Fix ClassNotFoundException for jackson lib

[rahulwagh]

I downgraded the -

1. Jackson 2 API ->2.10.3
2. Snakeyaml API -> 1.26.3

But after downgrade now I am stuck with following error (any inputs will be highly appreciated)

Try downgrading your Snakeyaml to 1.26.2.

I'm actually not sure which version of those 2 plugins introduced the breaking change, I roughly knew the date I had those installed for the first time and reverted to those versions.

[arundev4ops]

I have the same problem running Kubernetes v1.18.3. I'm running Jenkins v2.235.1 and all my plugins are up to date.

The workaround I've found for now is to downgrade Jackson 2 API to v2.10.3 and to downgrade Snakeyaml API to v1.26.2. If those 2 plugins are updated to their respective latest versions, the error message comes back.

Thanks. After all trail and errors , exact solution of yours worked for me.

[prydin]

Has anyone been able to find the root cause for this? I'm the maintainer of another Jenkins plugin (vrealize-automation-8) that suffers from the exact same issue. I'd love to find a way to fix my code instead of having users downgrade plugins. https://issues.jenkins.io/browse/JENKINS-64498

[apurvabhandari]

Still same issue. Error mentioned below. I tried with yml and yaml both facing same error. I have simple deployment manifest file(Kubernetes 1.18). Also tried downgrading and upgrading Jenkins but same error Jenkins 2.263.1 Snakeyaml API Plugin : 1.27.0 Kubernetes Client API Plugin : 4.11.1 Jackson 2 API Plugin : 2.12.0 Kubernetes plugin : 1.28.5

I've changed the plugin, I started to use this one https://plugins.jenkins.io/kubernetes-cli simple to integrate and works fine ;)

[gkhnsmsk]

can you maybe share your git repo so I can have a look into jenkinsfile?

[cardiff1982]

Are there any solutions for this issue?

still the same trouble...((

[mahusanin]

I have found the solution to this problem. I have tried many times and it's working perfectly. Kubernetes CD plugin should be Version 1.0. No need to downgrade other plugins.

[eggsbenjamin]

Hey @braunly thanks for the solution!

Also, i downgraded ECharts API and JUnit, but this plugins not required for kubernetes cd.

Please could you also provide the versions of these plugins which you downgraded to? Cheers

[chrouzz]

same problem, no fix yet?

Also, i downgraded ECharts API and JUnit, but this plugins not required for kubernetes cd.

Please could you also provide the versions of these plugins which you downgraded to? Cheers

I've switched to Kubernetes-cli plugin. Build my own Jenkins docker image with kubectl installed and happy to use kubernetes without this error. I don't remember exact versions, but you can try ECharts API Plugin 4.7.0-1 and JUnit 1.29. Maybe early.

For latest Jenkins (2.288) you need to downgrade a lot more plugins with many security fixes. Stop using kubernetes-cd plugin. Use something else or write your own.

I have found the solution to this problem. I have tried many times and it's working perfectly. Kubernetes CD plugin should be Version 1.0. No need to downgrade other plugins.

Using Jenkins 2.297 with v1.21.1+k3s1 cluster. Getting the same issue.

• Tried to downgrade to v 1.0 using .hpi file, but got error: io.fabric8.kubernetes.client.kubernetesclientexception: an error has occurred. hudson.remoting.proxyexception: io.fabric8.kubernetes.client.kubernetesclientexception: an error has occurred.
• Tried to downgrade Jackson 2 API & Snakeyaml API Plugin, Kubernetes Continuous Deploy plugin itself gone with many other plugins .. had to upgrade them again.

Any fix yet ?

Check this thread in StackOverflow https://stackoverflow.com/questions/62688901/class-not-found-io-kubernetes-client-openapi-models-v1service/68437162#68437162

The solution is just to downgrade the plugin Kubernetes Continuous Deploy to 1.0
