I have a C++ .dll in my java Spring Boot project.
Everything looks good and method from .dll is called when:
- I run application from IDE
- I compile file with
mvn pack & java -jar target/Project-0.0.1-SNAPSHOT.jar
I tried to copy project to another machine and I got this problem:
When I run application from IDE everything is ok
When I run same command on project
mvn pack & java -jar target/Project-0.0.1-SNAPSHOT.jarand it's called.dllmethod it crash with message error:
java.lang.UnsatisfiedLinkError: The specified module could not be found.

If I move .dll file in project root directory it works.

You are using JNA inside your project. JNA requires some native libraries be properly installed. E.g. it needs jnidispatch.dll for Windows platform.
For your case, you need to download the required native libs, e.g. https://github.com/java-native-access/jna/blob/master/lib/native/win32, and put it into a directory where can be searched by your JAVA.
