I was recently trying to install OpenCV (the java distribution) on a 64 bit windows 10 computer in the intelliJ IDE. I followed the steps in this tutorial in order to do so, and created an example program to see if the installation worked (see below).
import org.opencv.core.Core;
public class IsMyInstallBuggy {
static {System.loadLibrary(Core.NATIVE_LIBRARY_NAME);}
public static void main(String args[]) {
System.out.println(Core.NATIVE_LIBRARY_NAME);
}
}
I get this error when I try to run it:
"C:\Program Files\Java\jdk-10.0.1\bin\java.exe" -Djava.library.path=C:\Users\user\Desktop\opencv\build\java\x64 "-

I've tried adding the location of the OpenCV .dll to the system path but it didn't change the error. I also tried redownloading the OpenCV win-pack and redoing the same process. I also have tried this process on other computers running multiple versions of 64 bit windows (7,8, and 10) and had them all work. I read in another post somewhere (I forget which one otherwise I would link it) that this error is due to the .dll being dependent on other .dlls that it can't find (this was in a custom OpenCV build though), but as an experiment, I tried running this program using the steps described in the tutorial with only the .jar and the .dll (no extra folders that come with the distribution) and it still worked. I have hit a wall with this problem and have no idea what to do. Any help would be greatly appreciated. Thank you! (I forgot to mention, I am using the latest edition of intellij community edition)
