anyone happen to have a boot task for writing ONLY a resulting (uber)jar file to disk? not all of target/ incl the full class hierarchy etc.

i think that's what sift does https://github.com/dundalek/closh/blob/master/build.boot#L19

ah, awesome. i now remember seeing that one. thanks

bootstrap master now supports “features” Which are behaviors within boot that are toggled with env-vars, boot properties or cli args

A feature is a general abstraction built on Clojure spec

It takes a piece of data to be spec’d and a map consisting of keywords which are specs and an error messages to throw when the spec fails.

Features are implemented by a multi-spec and be extended anywhere within boot.
