So, obviously gradle is needed! I can muck around with shadowJar and runShadow but what’s the Kotlin equivalent?
From what I’ve read, start with gradle init --type java-application and then add the kotlin plugin to the gradle build file. That’s fine, but, what should the Gradle build file look like, approximately? Hello world pls.
