 This application is nothing more than a basic class with a stub for a JUnit based test suite.
 It exposes a method called `hello` that accepts a string as input, and prints a hello message on the screen.
 
 The project structure is really simple, and you should consider these two resources:

 - `pom.xml`: project object model (POM) configuration file
 - `src/main/java/com/example/dep/Dep.java`: source of our application

 Caching the `.m2/repository folder` (where all the Maven files are stored), and the `target` folder (where our application will be created), is useful for speeding up the process
 by running all Maven phases in a sequential order, therefore, executing `mvn test` will automatically run `mvn compile` if necessary.
