How to bundle model in to an executable Java JAR file?

I can run the code fine from IDE by referencing model folders placed in REOURCES or SRC folder like these.
**try(Model model = new Model("src/model2");
try(Model model = new Model("resources/model1");**

However,I can't seem to make it work once the code is compiled into an executable JAR file. I need the full thing bundled as a single JAR for my use case.

I tried many ways to reference it including following format
**try(Model model = new Model("jar:file:/Users/..../My_App.jar!/model1");**

How can we point to "resources/model1" so it still works when part of jar file? My project looks like this:

Start by inspecting the Java project layout shown in the issue, especially src/model2 and resources/model1, and compare how Model loads those paths in the IDE versus an executable JAR. Reproduce the packaged-JAR failure and determine what resource path or packaging arrangement makes the bundled model load successfully.
