YouTube API getting error when trying to compile - youtube-api

Question

I am using following code to try and retrieve the list of feeds from the YouTube API in a project that I build with maven.
YouTubeService service = new YouTubeService("dev","123456");
String feedUrl = "http://gdata.youtube.com/feeds/api/standardfeeds/most_viewed";
VideoFeed videofeed = service.getFeed(new URL(feedUrl), VideoFeed.class);
List<VideoEntry> videos = videofeed.getEntries();
When I do "mvn package" I get following error:
found : com.google.gdata.data.IFeed
required: com.google.gdata.data.youtube.VideoFeed
Is there anything that I am doing wrong?
My import looks like this:
import com.google.gdata.client.youtube.*;
import com.google.gdata.client.*;
import com.google.gdata.data.*;
import com.google.gdata.data.youtube.*;
import com.google.gdata.data.extensions.*;
import com.google.gdata.util.*;
import com.google.gdata.data.media.*;
import com.google.gdata.data.media.mediarss.*;
POM file. I added the artifactId using following method:
mvn install:install-file -DgroupId=youtube-12 -DartifactId=youtube-12 -Dversion=1.47.1 -Dpackaging=jar -Dfile=/usr/share/gdata/java/lib/gdata-calendar-2.0.jar
