Export to Runnable jar with additional built-in code libraries in eclipse

I am having trouble exporting my java project from eclipse as a jar executable. My Java project uses an external library (called jri). I exported the jri.jar file and set the library path for my native library in eclipse and it works great in development in eclipse. However, when I export it as a jar executable, I get the following error:

Cannot find JRI native library! Please make sure that the JRI native library is in a directory listed in java.library.path.

I placed a folder called lib in the same directory as my project jar; this lib folder contains the jri native library. jri native library is not in one file, but in a folder. This is the same setup as in eclipse.

How do I export my project to eclipse,

 Export... Java > Runnable JAR file Copy required libraries into a sub folder next to the generated Jar Finish

And my folder is organized this way

 folder project project.jar project_lib jri.jar jri native library folder

MANIFEST.MF of my project.jar:

 Manifest-Version: 1.0 Class-Path: . project_lib/jri.jar Main-Class: index

What I want to achieve is to give the other person a folder, including project.jar, and all that is needed so that he / she can run it without having to install anything else. Many thanks

Add a script containing something like this:

 #!/bin/bash java -Djava.library.path=project_lib/native/ -jar project_lib/jri.jar

I export some Java projects this way.

It is quite difficult to implement. The solutions I've seen include extracting your own libraries in the JAR into the temp OS directory, and then loading it. I would go for a complete solution for this. One Jar and Java Class Loader support it, and on the second page you will find links to similar tools.

You can put the libraries inside in your jar:

Export...

Java> Downloadable JAR file

Required libraries for packages in the created bank

Done

I always export this way. I don't know if this will work in your case, but it's worth a try.

Edit:

See these links:

My guess is that this is incorrectly associated with LD_LIBRARY_PATH. Or the file he is looking for is not listed in the specified path.

You know that I had similar problems.

 Could not extract native JNI library.

all of the above suggestions cannot help me. I could not stop and start deamon gradle using the following command:

 gradle --stop

I saw that deamon gradle is still not stopped in my processes. That's why I kill him in my process, and everything will be fine :)
