Clojurians Log v2

using cognitect’s aws api for the first time, and getting an error: Exception in thread "async-dispatch-1" java.lang.NoClassDefFoundError: org/eclipse/jetty/util/thread/NonBlockingThread when attempting to invoke (def s3 (aws/client {:api :s3})) per the example in the readme. if anyone has any ideas what could be causing that, I’m all ears

what are your deps?

using a lein project.clj, which I assume is the root of the issue

first time using a lib that declares its deps using deps.edn afaik, so if I’m missing something about how those might fit together that’s likely it

@mss lein is fine, paste your deps --- you'll need three

[com.cognitect.aws/api "0.8.301"]
[com.cognitect.aws/endpoints "1.1.11.537"]
[com.cognitect.aws/s3 "714.2.430.0"]

that seems correct

yeah no weird exclusions that I can tell either

can you paste the output of lein deps :tree

get the same error regardless of whether I add the ring/jetty-io exclusion or not

are you sure?

lemme sanity check it just to be sure. gimme a sec

it looks like ring-jetty-adapter is forcing an older version of jetty (9.2)

thank you for the help btw!

n.p.

aws-api needs jetty 9.3 IIRC

fwiw, if I bump my ring version to 1.7.1 (latest IIRC) and it defaults to using the cognitect jetty-io version, I get a different error about thread pool exhaustion

lemme run through the with/without exclusion on ring 1.6.3 and I can get you the error message on ring 1.7.1

jetty should be at "9.3.7.v20160115" when you'll have everything working correctly

yep, just went ahead and added that specific version to my deps and all is well

thanks for the help troubleshooting

my pleasure
