Java / Quarkus Interview questions

How do you create a new Quarkus project?

The most common way to scaffold a new Quarkus project is through the Quarkus Maven plugin's create goal, or equivalently through the code.quarkus.io web-based project generator, both of which let you pick a group/artifact ID and a starting set of extensions.

mvn io.quarkus.platform:quarkus-maven-plugin:create \
  -DprojectGroupId=com.example \
  -DprojectArtifactId=my-app \
  -Dextensions="resteasy-reactive,jdbc-postgresql"

The Quarkus CLI offers an even shorter equivalent, quarkus create app com.example:my-app, and both approaches generate a ready-to-run project with a Maven or Gradle build file, a default REST resource, test scaffolding, and a Dockerfile for both JVM and native builds already included.

From there, extensions can be added or removed at any time with quarkus extension add <name> without needing to regenerate the whole project, which keeps the initial setup decision low-stakes.

What tool provides a web-based Quarkus project generator?
Can extensions be added after the project is already created?
