创建List字符串的最佳构造是什么？是Lists.newArrayList()(来自番石榴)还是new ArrayList()？

这只是个人偏好吗？
或者只是键入泛型类型推断？
或者使用Lists.newArrayList()是否有任何理论或实践价值？

我收到以下错误:

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

这来自以下代码:

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("root@gmail.com", "pa$$word");
    } catch (AuthenticationException ex) {
      Logger.getLogger(TestProject.class.getName()).log(Level.SEVERE, null, ex);
    }
  }
}

起初,我在http://code.google.com/p/gdata-java-client/downloads/list中包含了每个库,并且还导入了比我需要的更多的库.我已经删除了我认为不必要的库(感谢thinksteep).所以我目前包含的库是以下库:

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 …
