Tests all run fine but the program fails when I call to run it manually?

[Jonathan-Zollinger]

I'm writing a learning project to compare performance between tech stacks. I thought I was squared away with the micronaut jdbc implementation of the backend since my tests were passing, but when I try to run ./gradlew run or compile to native, I get an error stating that my application file can't be found. I'm pretty perplexed by this - I worry that this is a really simple problem that I'm not grasping. Can someone give me a hand? I've put this in a repo just for this discussion here:

https://github.com/Jonathan-Zollinger/northwind-jdbc-api

the project uses testcontainers, I was lazy and hardcoded my linux user # in the test script, so you may need to edit line 57 in the build file if you're not using windows.

this is the error I get when I attempt ./gradlew run:

./gradlew run

./gradlew run

any help is greatly appreciated.

nevermind, it looks like with kotlin you have to add Kt to the application class name in the build file.
