Hello! How can I set the target JDK version when building a Jar with depstar? I do need to target JDK 1.7, but I couldn't find how...

clojure is unsupported on JDK 1.7

well, clojure >= 1.10.0

This is a legacy app, where JDK is in place.. so Clojure 1.8.0 as well

Well, if you can tell Clojure itself to target 1.7 via JVM opts, you can tell depstar to use those opts for compilation https://cljdoc.org/d/com.github.seancorfield/depstar/2.1.267/doc/all-the-options

(I don't know if such JVM options exist for Clojure?)

You'll already need an alias for Clojure 1.8 and you'll need to supply that to depstar via :aliases right?
