unresolved compilation process

Hello. This might be easy for someone but I have dealt with several errors today and this being the last error that i just could not figure out. I am a newbie so pardon me if i am clueless...within my eclipse ide i am getting this error:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:

at edu.cmu.sphinx.demo.robottest.RobotTest.main(Robot Test.java:19)

When i lookup like 19 (which I have tried to make changes to so its not the way it was yet there is still an error):

Code Java:

---

package edu.cmu.sphinx.demo.robottest;
 
import edu.cmu.sphinx.frontend.util.Microphone;
import edu.cmu.sphinx.recognizer.Recognizer;
import edu.cmu.sphinx.result.Result;
import edu.cmu.sphinx.util.props.ConfigurationManager;
 
public class RobotTest {
 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ConfigurationManager cm;
 
        if (args.length > 0) {
            cm = new ConfigurationManager(args[0]); 
        } else {
            cm = new ConfigurationManager(RobotTest.class.getResource("robottest.config.xml"));
        }  
 
        Recognizer recognizer = (Recognizer) cm.lookup("recognizer");
        recognizer.allocate();
 
        // start the microphone or exit if the programm if this is not possible
        Microphone microphone = (Microphone) cm.lookup("microphone");
        if (!microphone.startRecording()) {
            System.out.println("Cannot start microphone.");
            recognizer.deallocate();
            System.exit(1);
        }
 
        System.out.println("Say: anything from the RobotTest.gram");
 
        // loop the recognition until the programm exits.
        while (true) {
            System.out.println("Start speaking. Press Ctrl-C to quit.\n");
 
            Result result = recognizer.recognize();
 
            if (result != null) {
                String resultText = result.getBestFinalResultNoFiller();
                System.out.println("You said: " + resultText + '\n');
            } else {
                System.out.println("I can't hear what you said.\n");
            }
        }
 
	}
 
}

I will appreciate any help!

This is going to be hard for us to test as you are using the non standard import edu.cmu.sphinx..

Where can we download this from? I suggest Googling the Exception.

Which line is the one with the error? Can you copy and paste it here
or edit the original post and comment it: //<<<<<<<<< LINE with error
