How to authenticate with a Google Service Account in Jenkins pipeline

I want to use gcloud in Jenkins pipeline and therefore I have to authenticate first with the Google Service account. I'm using the https://wiki.jenkins.io/display/JENKINS/Google+OAuth+Plugin which holds my Private Key Credentials. I'm stuck with loading the credentials into the pipeline:

withCredentials([[$class: 'MultiBinding', credentialsId: 'my-creds', variable: 'GCSKEY']]) {
    sh "gcloud auth activate-service-account --key-file=${GCSKEY}"
}

I also tried it with from file, but without luck.

withCredentials([file(credentialsId:'my-creds', variable: 'GCSKEY')]) {

The log says:

org.jenkinsci.plugins.credentialsbinding.impl.CredentialNotFoundException: Credentials 'my-creds' is of type 'Google Service Account from private key' ....

You need to upload your Sevice Account JSON file as a secret file. Then:

withCredentials([file(credentialsId: 'key-sa', variable: 'GC_KEY')]) {
    sh("gcloud auth activate-service-account --key-file=${GC_KEY}")
    sh("gcloud container clusters get-credentials prod --zone northamerica-northeast1-a --project ${project}")
  }
