/**
 * A Maven artifact is a file, typically a JAR, that is produced and used by Maven projects.
 * It is identified by a unique combination of a group ID, artifact ID, version, classifier,
 * and extension, and it is stored in a repository for dependency management and build purposes.
 *
 * <p>Each {@code Artifact} instance is basically an exact pointer to a file in a Maven repository.
