## Resource Requirements

### Development Team
- 2-3 Senior Java developers with SMB protocol expertise
- 1 QA engineer for test infrastructure
- 1 DevOps engineer for CI/CD setup

### Timeline
- **Total Duration**: 6-8 months for all features
- **Phases 1-2**: 2-3 months (High priority)
- **Phases 3-4**: 2 months (Medium priority)

     *   <li>All attached artifacts in the order they were attached</li>
     * </ul>
     * The contents depend on the current lifecycle phase when this method is called, as artifacts
     * are typically attached during specific phases (e.g., sources jar during package phase).
     *
     * @param project the project to get artifacts for
     * @return an immutable ordered collection of all project artifacts

 * <p>
 * This interface allows plugins and extensions to define and register additional build lifecycles
 * beyond the standard ones provided by Maven (like clean, default, site). Lifecycles define a sequence
 * of phases that can be executed during a build.
 * <p>
 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism
 * and their provided lifecycles will be available throughout the Maven build process.

     * present, are appended, to those specified on CLI input, if any.

- : `kubeadm upgrade apply` now supports phase sub-command, users can use `kubeadm upgrade apply phase <phase-name>` to execute the specified phase, or use `kubeadm upgrade apply --skip-phases <phase-names>` to skip some phases during cluster upgrade.
