I am trying to migrate an existing App Engine app to Maven but I am running into a problem with generating datastorecallbacks.xml, so I tried to start a project from scratch using this tutorial: https://developers.google.com/appengine/docs/java/tools/maven and then added:
#PostPut(kinds = {"Greeting"})
void updateCache(PutContext context) {
Entity greeting = new Entity("Test", "test");
DatastoreService datastore =
DatastoreServiceFactory.getDatastoreService();
datastore.put(greeting);
}
The full source code can be found here: https://github.com/bogdan-nourescu/AppEngineMavenTest
The build fails with this error message:

I am trying to execute the maven project from java main
Please refer the code below.
public static void main(String args[]) throws MavenInvocationException
{
InvocationRequest request = new DefaultInvocationRequest();
request.setPomFile( new File( "C:\\Users\\DPKA764\\git\\be.axa.testautomation.phoenixiard\\pom.xml" ) );
request.setGoals( Arrays.asList( "clean", "install" ) );
Invoker invoker = new DefaultInvoker();
invoker.setMavenHome(new File("C:\\J\\apache-maven-3.5.3"));
System.out.println(""+invoker.getMavenHome());
invoker.execute( request );
System.out.println("suites are completed");
}
and when i execute the code as 'Java Application' it is throwing the following error.
[WARN] Maven will be executed in interactive mode, but no input stream has been configured for this MavenInvoker instance.

but when i execute the project directly as Maven Test It will run fine.Please suggest any changes i have to do
I'm trying to do this tutorial from Java EE 8 tutorial.
I'm following the instructions on how to install tutorial archetypes, which I've downloaded from this repository.
Error message printed in the bottom.
Is this related to the fact that the repository is archived, and the tutorials are outdated, or am I doing something wrong?

From the comments:
You need a full JDK (Java Development Kit), not a JRE (Java Runtime Environment)
Download a JDK from OpenJDK or Oracle, then set the environment variable JAVA_HOME to the root folder of your JDK.
Then re-try your Maven command
