Hi,
AppEngine Java11 does not have support for the local appserver emulator,
as any type of workload can be used (not a Jetty Servlet Server anymore).
So for Java11, the DevAppServerRunner run action is not available (or
produces this type of error). Only the deployment action is possible.
In order to test locally your application, you would have to locally run
the equivalent of your entrypoint (in app.yaml). A default one is a
command like
java -jar myjar.jar if this is your application in the jar.
Cheers,
Ludo

Hi I'm trying to migrate existing app engine standard model (JDK8) to
Java11 according to the guide at Google cloud
https://cloud.google.com/appengine/docs/standard/java11/java-differences
<https://cloud.google.com/appengine/docs/standard/java11/java-differences>
There is no issue on compile, but we I try to run on local development
server it generates this error. I'm using maven and tried "maven
package appengine:run".
Please find my error as below
Any guide and information will be appreciated.
