Chapter 4. Compiling and starting the Quarkus Getting Started project

After you have created the Quarkus Getting Started project, you can compile the Hello application and verify that the hello endpoint returns hello.

This example uses the Quarkus built-in development mode. In development mode, you can update the application sources and configurations while your application is running. Your changes will appear in the running application.

Prerequisites

  • You have created the Quarkus Getting Started project.

Procedure

  1. To compile the Quarkus Hello application in development mode, enter the following command from the project directory: 

    ./mvnw compile quarkus:dev

    The following example shows the output of this command: 

    [INFO] --------------------< org.acme:getting-started >---------------------

  2. Enter the following command in a new terminal window to send a request to the endpoint provided by the application: 

    curl -w "\n" http://localhost:8080/hello
hello
    Note

    This example uses the "\n" attribute to automatically add a new line before the output of the command. This prevents your terminal from printing a '%' character or putting both the result and the next command prompt on the same line.

  3. Press CTRL+C to stop the application.
