Maven Repository Metadata Model

 This is strictly the model for Maven Repository Metadata, so really just plain objects.

 The metadata file name is:

 * <<<maven-metadata.xml>>> in a remote repository,

 * <<<maven-metadata-\<repo-id>.xml>>> in a local repository, for metadata from a repository with <<<repo-id>>> identifier.

 []

                    <repositories>
                        <repository>
                            <id>child1-repo</id>
                            <url>https://child1.example.com/repo</url>
                        </repository>
                    </repositories>
                </project>
                """);

            // Create child2 with different repository
            Path child2Dir = tempDir.resolve("child2");
