Hello,

I tried to follow the steps in the readme (mvn clean appengine:devserver) and I saw this error:

[ERROR] Could not find goal 'devserver' in plugin com.google.cloud.tools:appengine-maven-plugin:2.3.0 among
 available goals cloudSdkLogin, deploy, deployAll, deployCron, deployDispatch, deployDos, deployIndex, 
deployQueue, genRepoInfoFile, help, run, stage, start, stop -> [Help 1]

If I use appengine:run I get this error:

appengine:run is only available for appengine-web.xml based projects

Which sample are you using?

I'm trying to model some existing code from the helloworld-gae-javasdk-tools example.

That example is using the deprecated App Engine SDK based plugin, com.google.appengine:appengine-maven-plugin. However, the README was updated to use the recommended Cloud based SDK, com.google.cloud.tools:appengine-maven-plugin. The new command would be mvn appengine:run.

@averikitsch - when I use mvn appengine:start I get the following error (same as mvn appengine:run:

appengine:run is only available for appengine-web.xml based projects

What options exist to run a YAML-based configuration?

Sorry @kdunn926, I misspoke. Please ensure you have the following:

If you want to use app.yaml from your root directory, you must upgrade to Java 11. Learn more here. With the Java 11 runtime, you must provide your own server for example Spring Boot with Jetty or Tomcat. The appengine:run goal does not work for app.yaml based projects because each server has a different start up command ie spring-boot:run for Spring Boot.
