java.lang.NoClassDefFoundError when using twitter hosebird

Question

I am trying to use Twitter Streaming APIs so that I can filter some tweets real time and display. I am trying to follow https://github.com/twitter/hbc .

I am not used to using Maven, so I found this jar file at http://www.java2s.com/Code/Jar/h/Downloadhbccore140jar.htm . I simply added it to my build path and ran the following code.

 BlockingQueue<String> queue = new LinkedBlockingQueue<String>(10000);
     StatusesFilterEndpoint endpoint = new StatusesFilterEndpoint();

However, I get the following Error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/client/methods/HttpUriRequest
    at com.twitter.hbc.core.endpoint.BaseEndpoint.<init>(BaseEndpoint.java:40)
    at com.twitter.hbc.core.endpoint.DefaultStreamingEndpoint.<init>(DefaultStreamingEndpoint.java:35)

    at StreamingApi.main(StreamingApi.java:36)
Caused by: java.lang.ClassNotFoundException: org.apache.http.client.methods.HttpUriRequest

    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:360)

I even tried the same by using Maven to compile and converted the compiled classes to jar files and then use then. However, I get the same error. It looks like there are few internal dependencies which are not resolved.

Could someone please help me with it. Thanks in advance.

It is difficult to find each jar manually and add to the build path and test. So, I finally learned to use Maven - https://github.com/twitter/hbc .

However, the Guava library was an old one and generated some errors. I used Guava-18.0 from https://code.google.com/p/guava-libraries/ and it works fine.
