Progress bar in text environemnt..

Question

I am trying to run the following in order to create a progress bar and show some activity during run time of my program.
The problem lies i believe in maven as i running JUnit tests and in order to work maven is used.
If the JUnit is runned inside Eclipse then it works fine , but trying to run it through my terminal running mvn test doesnt.
There is nothing i can change in this, it was here when i come and it works perfectly for eveyone else.
The problem i am facing is that out.print will not be executed until a println is.
I am wondering if someone that has used maven before has any experience in how to by bypass this problem and add my progress bar in my system.
source code ....
           * Creating of the activity bar diagram. ** Maven fault doesnt allow print **
           * @param text
           * @param backspaceSize
           * @return int
           *                The length of the string that was displayed, in order to be removed when called again.
          public static int activity(String text, int backspaceSize) {
               // Setting the printstream
               PrintStream pw = new PrintStream(System.out, false);
               // in order to remove the previous text it will take the length and remove accordingly.
                try {
                     for ( int i=0; i < backspaceSize ; i ++ ) {
                          pw.print("\b");
                    //seting the text to display
                    text = " " + getPosition() + " - " + text;           // append an expty space to distinquish from the whole one.
                    pw.print(text);
                    pw.flush();
                 } catch (Exception ex) {ex.printStackTrace();}
             return text.length();
               * Will return the value of the array to create an activity diagram
               * @return Array value
             private  static String getPosition (){
                i++;
               String array[] = {"\\","-","/","|"};
               if ( i == 4) { i = 0 ; }
               return array;

If it works for everyone else, are you using the same version of maven?
