26 * A simple filter to include artifacts from a list of patterns. The artifact pattern syntax is of the form:
27 *
28 * <pre>
29 * [groupId]:[artifactId]:[extension]:[version]
30 * [groupId]:[artifactId]:[extension]:[classifier]:[version]
31 * </pre>
32 * <p>
33 * Where each pattern segment is optional and supports full and partial <code>*</code> wildcards. An empty pattern
34 * segment is treated as an implicit wildcard. Version can be a range in case a {@code VersionScheme} is specified.
35 * </p>
36 * <p>
37 * For example, <code>org.apache.*</code> would match all artifacts whose group id started with
38 * <code>org.apache.</code> , and <code>:::*-SNAPSHOT</code> would match all snapshot artifacts.
