                    .build());

        // only keep repositories other than 'central'
        builder.pluginRepositories(pruneRepositories(model.getPluginRepositories()));
        builder.repositories(pruneRepositories(model.getRepositories()));
        return builder;
    }

The example also defines a file-based Maven repository with the name "myRepo". Such a file-based repository is convenient for a sample, but real-world builds typically work with HTTPS-based repository servers, such as Maven Central or an internal company server.

=== Using libraries that are not modules

You probably want to use external libraries, like OSS libraries from Maven Central, in your modular Java project.
Some libraries, in their newer versions, are already full modules with a module descriptor.
For example, `com.google.code.gson:gson:2.8.9` that has the module name `com.google.gson`.
