In the previous chapter, you learned how to define dependencies for your project. Those dependencies are mostly stored somewhere in a repository or a directory structure. A repository usually has a structure to support different versions for the same dependency. Also, some metadata, such as the other dependencies for a module, is saved in the repository.

In our build files, we must define the location of a repository for our dependencies. We can mix different types of repositories, such as Maven and Ivy. We can even use a local filesystem as a repository. We will see how we can define and configure repositories in our build files.

Also, Gradle offers the option of configuring the repository layout, if the repository is using a custom layout. We will learn how to provide credentials for repositories with basic authentication.
