Thank you for this contribution @Viniberaldo.
The idea is to replace the existing code with tests. So, you need to move the example to the test and remove the original class.
Also, since we'll use tests, we can change the example to not print the formatted message. In the original code, I've printed it to the console so people can see the result. Now that we'll have a test, the test itself is the verification. So all the boilerplate you had to add to verify the output can be removed.
See what I did here, for example: https://github.com/hbelmiro/100DaysOfJava/pull/62/files

This is not needed. It's already set in the root pom.xml.
