Micronaut-core: Creating first Micronaut sample with maven dependencies

[mOo7King]

I followed this (http://guides.micronaut.io/creating-your-first-micronaut-app/guide/index.html) guide but instead of generate a Gradle project I created a new project with maven dependencies.

In that way I only have two classes: Application.java and HelloController.java.
My purpose was to simply run Application.java in Intellij's IDE.

Expected Behaviour

What I expected was the creation of a random port localhost which I would be able to invoke with, for example, postman's application.

Actual Behaviour

What really happens is that when I run the class the following message appears:

_"io.micronaut.runtime.Micronaut start
INFO: No embedded container found. Running as CLI application"_.

Environment Information

• Operating System: Microsoft Windows 10 Enterprise (v. 10.0.16299)
• Micronaut Version: 1.0-SNAPSHOT
• JDK Version: started with 10 but currently 1.8.0_181 (_downgraded to check if would solve the issue_)
• IDE: Intellij Idea (_with Annotation Processing enabled_)

Code

HelloController.java

package example.micronaut;

import io.micronaut.http.MediaType;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;
import io.micronaut.http.annotation.Produces;

@Controller("/hello") 
public class HelloController {
    @Get("/") 
    @Produces(MediaType.TEXT_PLAIN) 
    public String index() {
        return "Hello World"; 
    }
}

Application.java

package example.micronaut;

import io.micronaut.runtime.Micronaut;

  public class Application {
    public static void main(String[] args) {
        Micronaut.run(Application.class);
    }
 }

@mOo7King On a Windows 10 machine, I took the following steps using Micronaut 1.0.0.M4 (git bash shell):

mn create-app test --build maven
cd test
./mvnw compile
./mvnw exec:exec

The application started successfully.

The pom.xml file you have there will definitely not work as there is more configuration that is required.

@jameskleeh Thanks for helping. It worked for me.
