Retrieve the sample project from Bazel’s GitHub repository.

    git clone https://github.com/b-mono/bazel-examples.git

The sample project for this tutorial is in the bazel-examples/springboot-sample directory and is structured as follow:

springboot-sample
|-- BUILD
|-- README.md
|-- WORKSPACE
|-- maven_dependencies.bzl
|-- maven_install.json
|-- maven_repositories.bzl
