com.google.cloud.core.ServiceOptions.getDefaultProjectId() does not work in App Engine local environment #2209
Description
APIs like google-cloud-pubsub require users to explicitly provide a project id.
When App Engine Maven Plugin is used to run locally using mvn appengine:run
ServiceOptions.getDefaultProjectId() returns no-app-id unless
<application>project-id</application> exists in appengine-web.xml
Note : returns project-id without the application entry when deployed to App Engine.
