in thread "main" java.lang.UnsatisfiedLinkError: no jnilept in java.library.path

Question

I have created a project for OCR

TessBaseAPI instance =  new TessBaseAPI();
instance.Init("C:\\TIAA Info\\tessdata","eng");
PIX image = lept.pixRead("C:\\TIAA Info\\tessdata\\test.png");
instance.SetImage(image);
BytePointer bytePointer = instance.GetUTF8Text();
String output = bytePointer.getString();
System.out.println(output);

After executing , I am getting following error

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jnilept in java.library.path

I have done the steps mentioned in the links but it was not working for me — Dave, Feb 27 '19 at 06:58
@Lino lept is class provided by javacpp which has a static native method pixRead. — Dave, Feb 27 '19 at 09:20
You'll also need to include JAR files with "linux", "macosx", and "windows" in their names. — Samuel Audet, Mar 06 '19 at 05:40

I hit this same error, turned out to be simply that I had defaulted to a 32 bit project, and the example is 64 bit. Changed that and it worked perfectly.
