If I app.properties in src/resources in a jar.
And load it in code I guess using Classloader.getResource()?

Can I override it at runtime? By I guess adding a different file but with same name into the classpath?

I would assume if you have a directory in the class path that is evaluated before the jar is analyzed, it might? Easy enough to testbed.

@SortOfTested was wondering if there was a formal order. Like if cp is /etc/*; lib/*.jar

Then even though the jar has app.properties, it will use etc/app. Properties?

Yes I guess could do trial and error but was wondering if there's a formal doc. Not sure what to Google for this but whatever I searched don't find what I wanted.

you can it override per commandline parameters

@stop like -Dapp.properties=x.properties?

getResources will return x assuming it's added to -cp x.propeties; ...

Actually yes I should just try it myself... But was wondering if there some formal doc that has the precedence order...

Whichever appears first in the classpath gets picked up

I'm glad I don't do Java 🤗

@ScriptCoded nobody asked

@yellow-dog That's correct!
