Developing Microservices with Quarkus

Quarkus comes with a toolchain that allows us to simplify creating, updating, and deploying our application. It can be used with various build tools.

# Maven

Quarkus offers good support for #key# Maven: A build automation tool. #key#. We can use a Maven command to create our project:

mvn io.quarkus.platform:quarkus-maven-plugin:2.15.3.Final:create \
    -DprojectGroupId=io.educative \
    -DprojectArtifactId=maven-test

The above command uses Maven to create a new Quarkus application with the given attributes. The full list of those attributes includes `projectVersion`, `javaVersion`, and `extensions`.

> **Note:** Quarkus creates a `.mvnw` folder and file, which is a wrapper for Maven and can be used directly via the `./mvnw` command.

After creating the project, we can list the available extensions with the command:
