Error ProjectConfig model class not found

[visay]

Hi @richid,

I followed the instruction at http://engineering.curalate.com/2016/09/29/programmatic-jenkins-jobs.html to setup a seed job manually in Jenkins and then I cloned your repo into its workspace to but I got the error as at the bottom.

What I know is snakeyaml is installed and loaded correctly with additional classpath libs/*.jar, dsl script call main.groovy only from the workspace root.

Jenkins version: 2.60.2 Job DSL Plugin version: 1.64

Any ideas how to fix that?

Hey Visay,

Thanks for reporting this! I ran into this a while ago and finally figured out the solution but I failed to record the update here. I just pushed a commit that should fix your issue. I'm also going to get the blog posted update to help prevent anyone else from hitting this.

Let me know if you still run into problems with that.

[visay]

Thanks for the commit. I'll test again and update here the result. It looks very promising :)

Hi @richid,

It works like a charm :+1:

Thanks a lot.

@febi881 I don't think this is related to your issue. It looks like you're using Jenkins Pipelines while the code in this repository is for the Job DSL Plugin. The latter is deprecated and I believe you want something like this.

[febi881]

I found the issue and updated the case https://issues.jenkins-ci.org/browse/JENKINS-62954 with the solution. This was because the slave pod was running in the jenkins master itself and I have made this change to force the pod to run on kubernetes cluster.

@richid thank for helping me.
