Quarkus requires even fewer lines of code than Micronaut! If everything works fine, we can find a file named quarkus-echo-1.0-SNAPSHOT-runner inside the ./target folder. To run in this mode, you compile your Quarkus application down to bytecode and run it on top of a JVM, similar to running more traditional Java workloads, using build tools like Maven and Gradle. Quarkus has been designed with this new world in mind, and provides first-class support for these different paradigms.
