I understand your point of view, but in fact, while you don’t need to technically know Java - the language - you’re still expected to understand how the java virtual machine and its ecosystem and tooling works.
So you don’t need to know how to write a java application, but still you need resources to understand what to do with your scala jars once you’ve written the code.
I guess Intellij will be able to package your application into an executable jar file.
Otherwise you should learn to use some build tool compatible with scala, sbt being the most popular - and generally considered not necessarily easy to use, after you’re past the basics -
Maven and gradle can be more familiar to people used to jvm programming, but I guess in general you need some basic understanding of how the Jvm, Jre, classpath and resources work in the JVM world.
