It's still a “Hello, World” example, but it does introduce some essential concepts.

The terms
repositories
and
dependencies
are part of the Gradle DSL. Any re-
quired libraries are listed in the
dependencies
block. There are several legal forms for
listing dependencies. The one used here is a string separated by colons. Using Maven syn-
tax is not an accident, as shown in the
repositories
section. Many different types of
repositories can be used, but here the standard Maven central repository is declared.
Executing the build this time runs the same series of tasks, but now any tests are executed
and a JUnit report in HTML form is produced in the build/reports/tests directory.
