This is from the project's Aether Demonstration and Examples site. I didn't try to run it, but it should be your answer.

public static void main( String[] args ) throws Exception
{
    System.out.println( "------------------------------------------------------------" );
    System.out.println( FindNewestVersion.class.getSimpleName() );

    RepositorySystem system = Booter.newRepositorySystem();

    RepositorySystemSession session = Booter.newRepositorySystemSession( system );

    Artifact artifact = new DefaultArtifact( "org.eclipse.aether:aether-util:[0,)" );

    VersionRangeRequest rangeRequest = new VersionRangeRequest();
    rangeRequest.setArtifact( artifact );
    rangeRequest.setRepositories( Booter.newRepositories( system, session ) );

    VersionRangeResult rangeResult = system.resolveVersionRange( session, rangeRequest );

    Version newestVersion = rangeResult.getHighestVersion();

    System.out.println( "Newest version " + newestVersion + " from repository "
        + rangeResult.getRepository( newestVersion ) );
}
