| /** |
| * An API to write Maven messages to console with styled color content, consistently across whole |
| * Maven ecosystem (Maven itself or any plugin or extension). |
| * <p> |
| * Messages are built with instances of {@link org.apache.maven.shared.utils.logging.MessageBuilder MessageBuilder} |
| * which provides a fluent API. |
| * {@link org.apache.maven.shared.utils.logging.MessageUtils MessageUtils} gives access to these buffers. |
| * <p> |
| * Plugins can use this API with any Maven version: color |
| * just won't be activated when run with Maven version older than 3.4.0. |
| * <p> |
| * Styles are:<ul> |
| * <li><code>debug</code>, <code>info</code>, <code>warning</code> and <code>error</code> for slf4j level display,</li> |
| * <li><code>success</code>, <code>warning</code>, <code>failure</code>, <code>strong</code>, <code>mojo</code> |
| * and <code>project</code> for message content</li> |
| * </ul> |
| * Default styles colors can be overridden through system properties, that can be set in <code>MAVEN_OPTS</code> |
| * environment variable (eventually in <code>.mavenrc</code> script):<ul> |
| * <li>system properties are named <code>style.<style name></code>,</li> |
| * <li>values are comma separated combination of <code>bold</code>, <code><color></code> and |
| * <code>bg<color></code> (for background), where <code><color></code> is |
| * an <a href="https://en.wikipedia.org/wiki/ANSI_escape_code#Colors">ANSI color</a>: <code>black</code>, |
| * <code>red</code>, <code>green</code>, <code>yellow</code>, <code>blue</code>, <code>magenta</code>, |
| * <code>cyan</code> or <code>white</code>, eventually with <code>bright</code> prefix</li> |
| * </ul> |
| * @since 3.1.0 |
