我正试图让 Twitter HBC 工作。我对Java没有太多经验，所以我尝试了他们的例子。但我总是收到此错误消息：

sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

和其他一些错误信息。我找到了这个错误的描述，但我不明白。

这是我的代码：

import com.twitter.hbc.ClientBuilder;
import com.twitter.hbc.core.Constants;
import com.twitter.hbc.core.endpoint.StatusesSampleEndpoint;
import com.twitter.hbc.core.processor.StringDelimitedProcessor;
import com.twitter.hbc.httpclient.BasicClient;
import com.twitter.hbc.httpclient.auth.Authentication;
import com.twitter.hbc.httpclient.auth.OAuth1;

import java.util.concurrent.BlockingQueue;
import java.util.concurrent.LinkedBlockingQueue;
import java.util.concurrent.TimeUnit;

public class SampleStreamExample {

    public static void run(String consumerKey, String consumerSecret, String token, String secret) throws InterruptedException {
        // Create an appropriately sized blocking queue
        BlockingQueue<String> queue = new LinkedBlockingQueue<String>(10000);

        // Define our endpoint: By default, delimited=length is set (we need this for our processor)
        // and stall warnings are on.
        StatusesSampleEndpoint endpoint = new StatusesSampleEndpoint();
        endpoint.stallWarnings(false);

        Authentication auth = new OAuth1("xxxxx", "xxxxxxxx", "xxxx", "xxxxxx");
        //Authentication auth = new com.twitter.hbc.httpclient.auth.BasicAuth(username, password);

        // Create a new BasicClient. By default gzip is enabled.
        BasicClient client = new ClientBuilder()
            .name("sampleExampleClient")
            .hosts(Constants.STREAM_HOST)
            .endpoint(endpoint)
            .authentication(auth)
            .processor(new StringDelimitedProcessor(queue))
            .build();

        // Establish a connection
        client.connect();

        // Do whatever needs to be done with messages
        for (int msgRead = 0; msgRead < 1000; msgRead++) {
            if (client.isDone()) {
                System.out.println("Client connection closed unexpectedly: " + client.getExitEvent().getMessage());
                break;
            }

            String msg = queue.poll(5, TimeUnit.SECONDS);
            if (msg == null) {
                System.out.println("Did not receive a message in 5 seconds");
            } else {
                System.out.println(msg);
            }
        }

        client.stop();

        // Print some stats
        System.out.printf("The client read %d messages!\n", client.getStatsTracker().getNumMessages());
    }

    public static void main(String[] args) {
        String consumerKey = "xxxxxxxxxxxxxxx";
        args[0] = consumerKey;
        String consumerSecret = "xxxxxxxxxxxxx";
        args[1] = consumerSecret;
        String token = "xxxxxxxxxxxxxxxxxx";
        args[2] = token;
        String tokenSecret = "xxxxxxxxxxxxxxxxxx";
        args[3] = tokenSecret;
        try {
            SampleStreamExample.run(args[0], args[1], args[2], args[3]);
        } catch (InterruptedException e) {
            System.out.println(e);
        }
    }
}

完整的错误是：

进程以退出代码 1 结束

在导入库或依赖项的过程中我是否搞砸了？你们能帮忙吗？

首先十分感谢！
