Error Deploying Endpoints Sample

In which file did you encounter the issue?

When following the instructions in appengine/endpoints-frameworks-v2/backend/README.md

Did you change the file? If so, how?

I only changed pom.xml, as instructed in the readme.

Describe the issue

Executing mvn appengine:deploy fails. First it hangs for a while after it says “Uploading X files to Google Cloud Storage” (as I indicated in the output below). Then after about 5 minutes it continues. Below is the full output, with my note near the bottom.

Note that this is about the third time I’ve tried; the first time it showed that it was uploading more than 0 files. I cannot find any errors in the cloud console logs.

It’s not obvious to me from these logs.

Might be a good idea to try using gcloud app deploy directly.

gcloud app deploy S:\Programming\git repositories\tmp\java-docs-samples\appengine\endpoints-frameworks-v2\backend\target\appengine-staging\app.yaml

I’m assuming that this doesn’t really have to do with the fact that it’s the maven plugin, but more the deployment, and if necessary we can redirect to the gcloud or deployment teams.

After an email conversation with @ersimont. They were able to resolve the issue recently with a git pull and gcloud components update.
