jib: jibDockerBuild fails to pull source image from gcr

Description of the issue: Unable to build Docker image from custom base image hosted in gcr with gradle.plugin.com.google.cloud.tools:jib-gradle-plugin:0.9.10

I’ve got Docker on the path: PATH=/Applications/Docker.app/Contents/Resources/bin:…

Already have the image locally after executing:

• gcloud auth configure-docker
• gcloud auth print-access-token | docker login -u oauth2accesstoken --password-stdin https://gcr.io
• docker pull gcr.io/ir-devops-playground/oracle-jdk1.8:alpine3.8

Environment:

• Mac El Capitan 10.11.6
• Docker version 18.06.1-ce, build e68fc7a

jib-gradle-plugin Configuration: Both my & service IAM account have “Storage Object Viewer” role. Tried 2 authentication approaches:

jib {
        from {
            image = "gcr.io/ir-devops-playground/oracle-jdk1.8:alpine3.8"
            auth {
                username = '_json_key'
                password =  file("${project.rootDir}/ir-devops-playground-33d34617c277.json").text
            }
        }
  }

&

jib {
        from {
            image = "gcr.io/ir-devops-playground/oracle-jdk1.8:alpine3.8"
            auth {
                username = 'oauth2accesstoken'
                password = 'gcloud auth print-access-token'.execute().text.trim()
            }
        }
  }

Log output:

./gradlew :impactradius-account:jibDockerBuild --stacktrace

Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':impactradius-account:jibDockerBuild'.

Additional Information: Originally tried pulling the image from our insecure Nexus Docker repo with allowInsecureRegistries=true but when that didn’t work, so I pushed the image up to gcr.
