In this example, `libs.guava` and `libs.junit.jupiter` refer to the corresponding libraries defined in your version catalog.

TIP: The `versions.junit.jupiter` syntax is used because the key contains a hyphen which is a special characters.

A version catalog provides a number of advantages over declaring dependencies directly in build scripts:

//
//	code-message line 1
//	code-message line 2
//	...
//	code message line n
//
// where code is a three-digit status code. The first line starts with the
// code and a hyphen. The response is terminated by a line that starts
// with the same code followed by a space. Each line in message is
// separated by a newline (\n).
//
