sound on a key press

hi guys, i'm working on my first interactive piece using makeymakey, i want to play a sound on a click / keyPressed. So far I've managed to get a sound played on a click, however it works only once then it stops, so if i try clicking again it doesn't play the sound again. Here's a bit of code i've written.

import ddf.minim.*;
import ddf.minim.analysis.*;
import ddf.minim.effects.*;
import ddf.minim.signals.*;
import ddf.minim.spi.*;
import ddf.minim.ugens.*;

import processing.sound.*;

Minim minim;
AudioPlayer one; //variable name

void setup(){
 // germanloop();
  size(500,500);
  minim = new Minim(this);
  one =minim.loadFile("german.wav");
  //germanloop();




}

void draw(){

  background(0);
  //sou =minim.loadFile("german.wav");

}

void mousePressed(){
 if (mousePressed == true);
  one.play();
}

void mouseReleased()
{
  if (mousePressed || true);
  one.close();

}
