 * <h3>Repositories</h3>
 *
 * <p>In Maven, <dfn>{@linkplain org.apache.maven.api.Repository repositories}</dfn> are locations where project artifacts (such as JAR files, POM files, and other
 * resources) are stored and retrieved. There are two primary types of repositories:<ul>

    /**
     * Main to test version parsing and comparison.
     * <p>
     * To check how "1.2.7" compares to "1.2-SNAPSHOT", for example, you can issue
     * <pre>java -jar ${maven.repo.local}/org/apache/maven/maven-artifact/${maven.version}/maven-artifact-${maven.version}.jar "1.2.7" "1.2-SNAPSHOT"</pre>
     * command to command line. Result of given command will be something like this:
