scala-cli Support Javap

Support Javap otherwise, I have to

scala-cli compile X.java -p

and then

javap -c .....very long path ....class

But wait, what exactly would you like to have here? javap as a new sub-command? what about scalap? Any context on motivation/usecase? is it just for convenience, so that you don't have to run it in 2 commands?

I suppose at the very least scalap would make sense, as we already have scaladoc...

is it just for convenience, so that you don't have to run it in 2 commands?

the biggest pain point is that I have to figure out what long path to pass to the second command:

% echo 'class C' > C.scala
% scala compile C.scala
Compiling project (Scala 3.7.3, JVM (21))
Compiled project (Scala 3.7.3, JVM (21))
% javap -classpath .scala-build/20250919_73d54800d9-854bc8c0b8/classes/main C
Compiled from "C.scala"
public class C {
  public C();
}

Btw. you can easily run that in Metals via the command metals.show-javap-verbose and similar. Also available under right click in the Metals Analyse menu

@tgodzik Thanks, I'm A java developer, and using IDEA :(, does Metals support the Scala Maven plugin? We are using Maven at work.

It should support Maven, but how do you mix it with Scala CLI actually, since this feature request is about it?
