[SOLVED] No such method error getComponentNames

No such method error getComponentNames

I'm new to this topic and I was trying to build a sample project using Sphinx4 libraries following this tutorial step by step: Tutorial link

then I kept having the same error from the (run.xml)

the code I used:

public static void main(String[] args) {
        // TODO code application logic here
        //configuration obj
        Configuration configuration = new Configuration();

        //path to acoustic model
        configuration.setAcousticModelPath("resource:/edu/cmu/sphinx/models/en-us/es-us");
        //path to dictionary model
        configuration.setDictionaryPath("/dictionary.dic");
        //path to the language model
        configuration.setLanguageModelPath("/languagemodel.lm");

        //recognizer object, pass configuration object

        try{

            LiveSpeechRecognizer recognize = new LiveSpeechRecognizer(configuration);
            recognize.startRecognition(true);

            //create SpeechResult Obj
            SpeechResult result;

            //checking if recognizer jas recognized the speech

            while((result = recognize.getResult())!=null){

                //get the recognized speech
                String command = result.getHypothesis();
                //Match recognized speech with our commands
                switch(command){

                    case "open file manager":
                        System.out.println("File manager Opened");
                    break;

                     case "close file manager":
                        System.out.println("File manager Closed");
                    break;

                     case "open browser":
                        System.out.println("Browser Opened");
                    break;

                         case "close browser":
                        System.out.println("Browser Closed");
                    break;


                }

            }
        }catch(IOException e){}



    }

the error I keep getting:

    BUILD FAILED (total time: 0 seconds)

I downloaded the jar files from this website oss.sonatype.org

and I added the file.dic, file.lm to the /src folder and to a separate folder to figure if this was the cause but no new results.
