Fat jar unable to find classpath file inside /resources package

[Puspender Tanwar]

I created a fat jar using Spring boot. Inside the bootstrap.yml I am trying to access a file which is under /resources only.
location: classpath:secret.json

But I am getting java.io.FileNotFoundException: class path resource [secret.json] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/Users/test/Downloads/Demo/demo-api/target/demo-api-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes!/secret.json

The same is working in IDE. What could be the wrong?

Here is the decompiled jar file structure screenshot and package structure

Do you use ResourceLoader to load the json file?

This is the issue with spring cloud config library.
