Hi Ludovic, The Java 11 page of App engine described the guide for running application locally as below,
To run your application locally: 1. Package your application: mvn clean package 2. Start the server with your WAR file as an argument. For example, you can start the server in the helloworld-servlet sample <https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine-java11/helloworld-servlet> by running the following command from your java-docs-samples/appengine-java11/appengine-simple-jetty-main/ folder: mvn exec:java -Dexec.args="../helloworld-java8/target/helloworld.war" 3. In your web browser, enter the following address: http://localhost:8080 On Friday, 22 November 2019 04:55:34 UTC+13, Ludovic Champenois wrote: > > 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).
