GRIP example code compile error

[randy_pham]

@Override
	public void robotInit() {
		UsbCamera camera = CameraServer.getInstance().startAutomaticCapture();
	    camera.setResolution(IMG_WIDTH, IMG_HEIGHT);
	    
	    
	    visionThread = new VisionThread(camera, new Pipeline(),  pipeline -> {
	         if (!pipeline.filterContoursOutput().isEmpty()) {
	            Rect r = Imgproc.boundingRect(pipeline.filterContoursOutput().get(0));
	            synchronized (imgLock) {
	                centerX = r.x + (r.width / 2);
	            }
	        }
	    });
	    visionThread.start();
		
	}

We are getting this error: The constructor VisionThread(UsbCamera, Pipeline, (<no type> pipeline) -> {}) is undefined.

We have included Pipeline.java in our package. The errors seems to be withing the listener lambda. We are using java 1.8 in eclipse.
