Why I specify lein repl Clojure version like this:

:repl {:dependencies
        [
         ^:displace [org.clojure/clojure "1.9.0"]
         ;; [cider/cider-nrepl "0.16.0-SNAPSHOT"]
         ]

But I launch lein repl still get Clojure 1.8.0

@stardiviner I just tested and found that it broke in 2.8.0

https://github.com/technomancy/leiningen/issues/2374

it works when I downgrade to 2.7.1 and breaks when upgraded to 2.8.0

I see. Thanks. @bostonaholic

np. I was really intrigued because I’ve used ^:displace successfully many times before. It was surprising to me that it didn’t work when I tried it.

so I had to get to the bottom of it

Me too. Luck that CIDER works fine.

I just used a deps.edn for the first time the other day and now I'm wondering about if/how it might integrate with leiningen

I assume this must have been talked about a lot already

oh there it is

I only had to scroll up two screens' worth to find it

I should have done that first

@gfredericks I wanted to hear about this too and haven’t seen it on here - I’ll start scrolling

@mikerod I meant https://github.com/RickMoynihan/lein-tools-deps

hah thanks

Cool

I upgraded to Java9 and am getting a classnotfoundexception for java/sql/Timestamp, it happens really early when I start leiningen, then I tried upgrading to 2.8.1 and got a not found excp for sun.misc.Launcher. Do I have to go back to Java 8 to use leiningen?

does this happen outside of a project with LEIN_NO_USER_PROFILES=1?

no, it seems to be working now, I guess that error when I did lein upgrade 2.8.1 didn't stop the upgrade from happening

It looks like things are working now, weird

@dealy see https://www.deps.co/blog/how-to-upgrade-your-clojure-projects-to-use-java-9/ if you have more issues
