我看到Twitter4j与Android有很多错误,但我没有在Android上使用它。我正在将它用于Bukkit(Minecraft插件)。出于某种原因,当我将twitter4j-core-3.0.3.jar添加到我的项目中时,在服务器控制台中加载时出现错误:

由于我是Java的新手,我真的没有得到我在这里做错的事。这是我的代码(我不认为这是问题,因为插件无法加载......:
String TWITTER_CONSUMER_KEY = "XXXXXXXX";
String TWITTER_SECRET_KEY = "XXXXXX";
String TWITTER_ACCESS_TOKEN = "XXXXXXXXXX";
String TWITTER_ACCESS_TOKEN_SECRET = "XXXXXX";
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true).setOAuthConsumerKey(TWITTER_CONSUMER_KEY).setOAuthConsumerSecret(TWITTER_SECRET_KEY).setOAuthAccessToken(TWITTER_ACCESS_TOKEN).setOAuthAccessTokenSecret(TWITTER_ACCESS_TOKEN_SECRET);
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
try {
Query query = new Query(Username);
QueryResult result;
do {
result = twitter.search(query);
List<Status> tweets = result.getTweets();
for (Status tweet : tweets)
{
String rawJSON = DataObjectFactory.getRawJSON(tweet);
try
{
BufferedWriter out = new BufferedWriter(new FileWriter((getDataFolder() + File.separator + "TwitterData.txt")));
out.write(rawJSON);
out.close();
}
catch (IOException ioe)
{
ioe.printStackTrace();
System.out.println("Failed to store tweets: " + ioe.getMessage());
}
}
}
while ((query = result.nextQuery()) != null);
System.exit(0);
}
catch (TwitterException te)
{
te.printStackTrace();
System.out.println("Failed to search tweets: " + te.getMessage());
System.exit(-1);
}
为什么Twitter4j无法正常加载?谢谢!
编辑:此外,twitter4j-core-3.03.jar位于我计算机上的另一个目录中。这是一个问题吗?
答案 0 :(得分:1)
Java程序所需的所有jar都需要位于服务器上的类路径中。这包括你的Twitter4J。
