If we want to add dependencies from a repository in a Gradle build file, we must explicitly add the repositories configuration block. Within the configuration block, we define the location of the repository and maybe some extra configuration.

// Repositories configuration block,
// must be present to define and
// configure repositories to get
// dependencies in our build script.
repositories {

  // Sample Maven repository with a
  // custom location.
