Add javac function (like leiningen has)

[ivarref]

Hi again

and thanks again for a great project!

leiningen has javac and it's more familiar if this command is also available in build.edn?

What do you think?
Thanks and kind regards!

@ivarref Thanks for your contribution!
Hmm, javac function may be more familiar but we already have java-compile function and it is easy to find by help function.
I don't want to have just an alias for another function for now.

Thanks for the quick response. That's fine. Best regards.
