Description
I've investigated into #216, but I can't quite get my Client Datastore connection to work with the App Engine Devserver.
I've tried:
# No environment variables, DatastoreOptions.defaultInstance().service()
com.google.datastore.v1.client.DatastoreException: Request had invalid authentication credentials.
# DATASTORE_EMULATOR_HOST=localhost:8080
# DatastoreOptions.defaultInstance().service()

Caused by: java.io.IOException: Application Default Credentials failed to create the Google App Engine service account credentials class com.google.appengine.repackaged.com.google.api.client.googleapis.extensions.appengine.auth.oauth2.AppIdentityCredential$AppEngineCredentialWrapper. Check that the component 'google-api-client-appengine' is deployed.
Caused by: java.lang.ClassNotFoundException: com.google.appengine.repackaged.com.google.api.client.googleapis.extensions.appengine.auth.oauth2.AppIdentityCredential$AppEngineCredentialWrapper
// Interestingly, this is trying to get `AppIdentityCredential` from "com.google.appengine.repackaged.com.google.api...", rather than from "com.google.api..."
Am I missing an environment variable for configuration to make this work nicely?
