Lets say that I have 4 Maven modules:
-main
|-core (OpenCV is included here)
|-web (REST services that should use core services with OpenCV)
|-app (simple desktop app that also uses OpenCV through core services)
I want to do it like this in order to have one module that deals with image processing and other modules that should use it.
Another hint: I am using Eclipse Mars (4.5.0).
My problem is that when I add OpenCV as native library (in Preferences), I can't compile my code with Maven since its getting errors like this:
[INFO] ------------------------------------------------------------------------

When I create class with main method, OpenCV works correctly.
So, I tried another approach: adding maven dependency on project (not the latest version, but still worth try...).
<!-- https://mvnrepository.com/artifact/nu.pattern/opencv -->
<dependency>
<groupId>nu.pattern</groupId>
<artifactId>opencv</artifactId>
<version>2.4.9-4</version>
</dependency>
This time, Maven compilation works fine, and if I have native class in Build Path, it seems to work properly for app module, but web module gives error:
19:53:05,575 ERROR [io.undertow.request] (default task-97) UT005023: Exception handling request to /SC/rest/snapshot/send: org.jboss.resteasy.spi.UnhandledException: java.lang.UnsatisfiedLinkError: no opencv_java310 in java.library.path
My question is: is it possible to include OpenCV library inside my core-services.jar so I wouldn't have to configure project? How can I configure server (WildFly 10) to properly use this library?
