How to build Java project with OpenCV using Maven?

Question

Java

You need to build a project that uses OpenCV. Everything would be great, but for some reason the libraries don't make it to the java.library.path. And when I try to run the code using the library, I get this error:

java.lang.UnsatisfiedLinkError: no jniopencv_highgui in java.library.path
