I get the following error:
Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.collect.ImmutableSet.of([Ljava/lang/Object;)Lcom/google/common/collect/ImmutableSet;

Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)
This comes from the following code:
package testproject;
import com.google.gdata.client.youtube.YouTubeService;
import com.google.gdata.util.*;
import java.util.logging.*;
public class TestProject {
public static void main(String[] args) {
try {
YouTubeService service = new YouTubeService("Test", "developerKey");
service.setUserCredentials("[email protected]", "pa$$word");
} catch (AuthenticationException ex) {
Logger.getLogger(TestProject.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
At first, I included every library in http://code.google.com/p/gdata-java-client/downloads/list and also imported much more than I needed to. I've since removed the libraries I deemed unnecessary (thanks thinksteep). So the libraries I'm currently including are the following libraries:
mail.jar
activation.jar
ant.jar
gdata-core-1.0.jar
gdata-media-1.0.jar
guava-11.0.1.jar
gdata-youtube-2.0.jar
gdata-youtube-met-2.0.jar
(There are probably a few libraries there which are not necessary... But I'm at my whit's end...) I'm just trying to test getting a YouTube service so I can get things going on this project, but no dice. Oh, and I've also included this library: http://code.google.com/p/guava-libraries because before I was getting a NoClassDefFound error and including that library seemed to solve it. Thank you in advance for the help! Oh, and I also followed every step exactly (or at least I think so) in the gdata getting started guide. My test build was successful by the end... Thanks again!
Adding more than required may cause issue too. java.lang.NoSuchMethodError error typically happens in case where runtime couldn't find required method with exact signature. Possible causes are:
1) There might be mulitple jars with same code, which may cause wrong class get loaded.
2) Incompatable version of jar, the jar you have in classpath might be older version/newer version.
Make sure none of those cases happening.
