mvn appengine:devserver [ERROR] Could not find goal 'devserver' in plugin com.google.cloud.tools:appengine-maven-plugin:1.3.1 among available goals

问题

Yes, I went through similar question on 'Goal' not found Error. But havent been able to solve my problem -

Im deploying my SpringBoot App to GCP and following this.

Had a few hiccups so far, but managed to overcome.

This time, the problem is that I added the goal, but still I see the same error. Like this ->

<plugin>
<groupId>com.google.cloud.tools</groupId>
     <artifactId>appengine-maven-plugin</artifactId>
     <version>1.3.1</version>
	     <configuration>
		    <project>${endpoints.project.id}</project>
	            <version>1</version>
	       		<devserver.host>localhost</devserver.host>
	       		<devserver.port>8888</devserver.port>
	        </configuration>
</plugin>

Also, I updated maven to latest version, did a 'mvn clean package' (which was successful build) and then did 'mvn appengine:devserver' and it says -

[ERROR] Could not find goal 'devserver' in plugin com.google.cloud.tools:appengine-maven-plugin:1.3.1 among available goals deploy, deployCron, deployDispatch, deployDos, deployIndex, deployQueue, genRepoInfoFile, help, run, stage, start, stop -> [Help 1]
[ERROR]

Any suggestions, warmly welcome!

Thanks.

There are two App Engine Maven plugins you can use to launch your SpringBoot app: App Engine SDK-based and Cloud SDK-based.

The App Engine SDK-based plugin should have the following groupId entry in pom.xml:

<groupId>com.google.appengine</groupId>

and the command to run the App Engine development web server is

$ mvn appengine:devserver

The Cloud SDK-based plugin should have the following groupId entry in pom.xml:

<groupId>com.google.cloud.tools</groupId>

and the command to run the App Engine development web server is

$ mvn appengine:run

In that case you were using the wrong command for the chosen plugin.

Using $ mvn appengine:run with your code should work.
