I try to convert work from appengine-web.xml file to work with app.yaml file in google app engine project, so I created app.yaml file and put it in main folder of project.
when I try to deploy my project with "gcloud app deploy" command
I get error
INVALID\_ARGUMENT: WEB-INF/appengine-web.xml is required for this runtime
if I run "gcloud app deploy path/appengine-web.xml" command
the deploy is work fine
