| /** |
| * An artifact descriptor reader that gets data from a simple text file on the classpath. The data file for an artifact |
| * with the coordinates {@code gid:aid:ext:ver} is expected to be named {@code gid_aid_ver.ini} and can optionally have |
| * some prefix. The data file can have the following sections: |
| * <ul> |
| * <li>relocation</li> |
| * <li>dependencies</li> |
| * <li>managedDependencies</li> |
| * <li>repositories</li> |
| * </ul> |
| * The relocation and dependency sections contain artifact coordinates of the form: |
| * |
| * <pre> |
| * gid:aid:ext:ver[:scope][:optional] |
| * </pre> |
| * |
| * The dependency sections may also specify exclusions: |
| * |
| * <pre> |
| * -gid:aid |
| * </pre> |
| * |
| * A repository definition is of the form: |
| * |
| * <pre> |
| * id:type:url |
| * </pre> |
| * |
| * <h2>Example</h2> |
| * |
| * <pre> |
| * [relocation] |
| * gid:aid:ext:ver |
