thanks but I need to know which dep to exclude. I should have been clearer in my question.

here’s the warning I see

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/steve/.m2/repository/com/fzakaria/slf4j-timbre/0.3.13/slf4j-timbre-0.3.13.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/steve/.m2/repository/org/slf4j/slf4j-nop/1.7.7/slf4j-nop-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See  for an explanation.
SLF4J: Actual binding is of type [com.github.fzakaria.slf4j.timbre.TimbreLoggerFactory]

I’m want to use timbre so this suggests I should exclude the slf4j-nop dep. when I examine my deps tree, that is a transitive dep from Clojure (via tools.deps). I can’t figure out how to exclude that completely, or if there’s a better way to do this?

@U0510KXTU something is wrong if your clojure depends on slf4j-nop

do you mean something other than org.clojure/clojure?

let me double-check….

quite right, it’s coming from datomic-free

datomic-free probably shouldn't depend on slf4j-nop, but yeah.

but there’s two more: from tools.gitlibs and tools.deps

I can’t see how they are getting in there

tools deps has a transitive slf4j dependency, which I've flagged up that it shouldn't have in https://clojure.atlassian.net/projects/TDEPS/issues/TDEPS-108?filter=allopenissues

I take it back. the extra one comes as part of tools.deps

is there a way to explicitely exclude that? maybe explicitely add tools.deps as a dep?

I think you just need to change your t.d.a dependency to have an exclusion of slf4j-nop?

I didn’t have a t.d.a dep in my deps

Where's it coming from?

I added one with the exlusion (same as datomic-free) but it’s still there for some reason. digging….

is this a cursive issue, i.e. does it not appear in clojure -Stree?

I think it might be. good idea, I’ll check from the CLI

quite right, not a problem from the CLI

I guess cursive is adding t.d.a to your deps for some reason?

you legend! despite the presence in Cursive, the warning has gone at load time. that fixed it

once again, you’ve helped me. thanks mate

if you are at Clojutre, I’ll buy you a beer

Unfortunately not, I'm at Heart of Clojure though on the chance you are, I know you struggle to get up for the european ones. I'm sure my fellow JUXTers will enjoy the beer though 🙂

I’ll pay it forward. I just listened to the Juxt-cast today and heard about XT20. might have to switch to that next year
