Thanks for filing!

Do you have any steps for reproducing this issue?

[aresares]

I used this pipeline with all required plugins installed:

• Jenkins 2.176.3
• JDK 15
• MAVEN 3.6.2
• Google Container Registry Auth Plugin v.0.3
• Google OAuth Credentials plugin v.1.0.2

pipeline {
  agent {
    kubernetes {
      label 'fiscalcode-pod'  			// all your pods will be named with this prefix, followed by a unique id
      idleMinutes 10  				// how long the pod will live after no jobs have run on it
      yamlFile 'build-pod.yaml'  		// path to the pod definition relative to the root of our project 
      defaultContainer 'jnlp-fiscalcode'  	// define a default container if more than a few stages use it, will default to jnlp container

Looking into this

[jason-kane]

I just got an identical traceback; essentially the same groovy. Nothing exotic. Relevant bit looks like:

REGISTRY='gcr.io/projectname'
GCR_CREDENTIALS='gcr:credential-id'

docker_image = docker.build(...)

    stage('Publish') {
        figlet STAGE_NAME
        docker.withRegistry(
            "https://${REGISTRY}",
            GCR_CREDENTIALS
        ) {
            docker_image.push('latest')
        }
    }

where credential-id is a json service account uploaded into a "Google Service Account from private key" credential.

Jenkins 2.249.1
Google OAuth Credentials 1.0.2
Google Container Registry Auth Plugin 0.3

I've re-uploaded the service account json and I'm retrying the build to see if I'm just unlucky, it's a crazy huge docker image.

--- UPDATE ---

Generating a new service account json and replacing the credential in Jenkins fixed this for me. I suspect but have not verified that the "old" service account json was disabled/removed in GCP. I suppose it is also possible but much less likely there was something about the old service account that broke jenkins.

Still a 'bug' but only in that java.lang.NullPointerException isn't a very helpful error message.

[aarnaud]

Any idea ? I still have the issue, with new service account

This is still an issue. It was working fine and now getting the similar error.
