+== Creating the Maven project

+First, we need to create a new Quarkus project with the following command:
+
+:create-app-artifact-id: command-mode-quickstart
+include::{includes}/devtools/create-app.adoc[]
+
+NOTE: The suggested project creation command lines disable the codestarts to avoid including a REST server. Similarly, if you use code.quarkus.io to generate a
+project, you need to go to *MORE OPTIONS -> Starter Code* and select *No* to avoid adding the RESTEasy Reactive extension.
+
+The RESTEasy Reactive extension is added automatically only if you ask for codestarts and you didn't specify any extensions.

+Each test method must be annotated with `@Launch` to automatically start the application or have a `QuarkusMainLauncher`
+parameter to manually launch the application.

 We can then extend this with an integration test that can be used to test the native executable or runnable jar:
