NoSuchFieldError: RESOURCE_PREFIX при использовании Tess4J с Eclipse

Question

Я попытался использовать Tess4J в Eclipse, но это приводит к ошибке в заголовке. Я импортировал эти файлы jar: tess4j, jai_imageio и jna. Код теста, который я написал, соответствует примеру, приведенному на странице примеров.

                File DMTfile = new File(System.getProperty("user.dir")+"\\DMTcap.bmp");
                BufferedImage DMTcap = ImageIO.read(DMTfile);Tesseract instance = new Tesseract();

                String result = "";
                try {
                    result = instance.doOCR(DMTcap);
                } catch (TesseractException e2) {
                    e2.printStackTrace();
                }
                System.out.println(result);

Полная ошибка заключается в следующем:

Как я могу это исправить?

Platform.RESOURCE_PREFIX является константой JNA. Убедитесь, что вы используете соответствующую версию JNA (4.1.0).
