Why don't I see any scheduled CRON Jobs in my Google App Engine Cloud Dashboard

[Shivang]

Hello there, 

I deployed a Java 8 Spring boot app on Google App Engine cloud. The app runs fine on the cloud, but for some reason, I don't see any scheduled cron jobs in the cron dashboard. Screenshot attached. 

It's blank, no scheduled jobs. 

I am not sure why. 

I have a cron.xml file with several cron jobs in the WEB-INF folder. In the local dev environment, I used POSTMAN client to test the code which is supposed to be triggered by CRON Jobs. 

The code is being triggered fine. Also, I see no CRON tab in the local GAE Dashboard. Screenshot attached. 

Maybe I am doing something wrong. Do I have to explicitly, like manually configure the CRON jobs in the cloud environment?
I went through the docs https://cloud.google.com/appengine/docs/standard/java/config/cron I don't think it says this anywhere. 

Any suggestions would be appreciated.

Hello Shivang, 

Do you use App Engine SDK, or Cloud SDK in your workflow? The page you linked to uses Cron with the XML cron configuration file; this is to be employed if you use App Engine SDK tooling, such as appcfg. If you use Cloud SDK-based tooling, such as the gcloud command line, or Cloud SDK-based Maven, Gradle, Eclipse, or IntelliJ plugins, refer to the YAML version of this page.
