Deploying multi-module appengine projects using service account

Question

All of my previous appengine projects were single module. I deploy them using gcloud since, as far as I know, this is the only tool supporting service account authentication (vs AppCfg & appengine maven plugin), which is a requirement for me.

I am now creating my first java multi-module project and based it on this sample: https://github.com/GoogleCloudPlatform/appengine-modules-sample-java

However, when I try to deploy the project, I get a

Bad argument: The requested action does not support EAR configurations
AppCfg [options] stage <app-dir> <staging-dir>

From what I understand, gcloud uses AppCfg to generate yaml configuration files and it does not support EAR configurations.

Is there a way to deploy this kind of project using a tool that supports service accounts?

Thanks!

You'll need to run mvn package to build the WAR folders of the modules (appengine-modules-guestbook/target/appengine-modules-guestbook-1-1.0, for example, given the link you posted). Once you've built those WAR folders, deploy them individually with mvn gcloud:deploy (read about this maven plugin at the link provided)
