Class Not Found Exception

[caryfitzhugh]

java.lang.ClassNotFoundException: com.amazonaws.auth.profile.ProfileCredentialsProvider

I am trying to use amazonica but get this failure when I require any amazonica.aws.* package.

Does anyone have ideas?

[mcohen01]

What version are you using? Can you post your code, and a trace?

[caryfitzhugh]

Downgrading to 0.2.29 seems to let me move forward. I needed to include joda-time explicitly - not sure if that matters.

[caryfitzhugh]

I'll go back to 0.2.30 and get you a trace

[caryfitzhugh]

going back to just 0.2.30, all I've done is try to run tests, and it's just requiring the sqs package that causes this error.

I have a similar issue with 0.3.1 which downgrading to 0.3.0 solved. In the ns:

(ns ingest-f0001.s3
   (:require [amazonica.aws.s3 :as s3]
             [clj-time.core :as t]))

from my project.clj:

:dependencies [[org.clojure/clojure "1.6.0"]
               [org.clojure/data.csv "0.1.2"]
               [yieldbot/flambo "0.4.0-SNAPSHOT"]
               [clj-time "0.8.0"]
               [amazonica "0.3.1" :exclusions [joda-time]]]

I was getting the error message:

Failed trying to require ingest-f0001.s3 with: java.lang.NoClassDefFoundError: Could not initialize class com.amazonaws.ClientConfiguration

There doesn't seem to be a problem building an uberjar or under lein repl, but it won't compile the ns clause inside Lighttable unless I downgrade. I'm cool for now, but I put this here as a data point. Thanks!

[mcohen01]

@caryfitzhugh and @alilee I think the problem in both your cases is a version conflict with Jackson. The >=1.9 Java SDK bumped the version from 2.1 to 2.3. So for instance, I had a slightly older version of cheshire in a project which would reproduce the NoClassDef error (for the ClientConfiguration). The fix was either upgrading cheshire to 5.3.1 or excluding jackson like so:

[cheshire "5.2.0" :exclusions [com.fasterxml.jackson.core/jackson-databind
                                                com.fasterxml.jackson.core/jackson-core
                                                com.fasterxml.jackson.core/jackson-annotations]]

Can you give that a try and let us know if that works?

[caryfitzhugh]

I don’t use cheshire. And so those changes didn't help me.

And I’m also a beginner, so maybe I’m mistaken. But - in the lib directory, I do see

jackson-core-asl-1.8.9.jar

jackson-mapper-asl-1.8.9.jar

I’m not sure how to discover who is including that - or if I need it… Or if excluding it is an option. Sorry. ​

If you're using leiningen, in the root of your project you can type lein deps :tree, which will print out the dependency tree for your project. Then you can search for jackson to see what other libraries depend on it and the versions they're pulling in.

[caryfitzhugh]

Ahh... Rotary is including it (I'm converting over from rotary to amazonica... Just too many AWS services I use, can't have a lib for each :) ) I will touch base again once the conversion is complete, and I'll try to roll amazonica back up to 0.2.30

Thanks!

@alilee I think the problem manifests when using LightTable because they have a dependency on fetch, which pulls in jackson 2.0.0 via cheshire 4.0.0 via lib-noir via noir. Maybe you can ask the LightTable devs how to specify exclusions in the IDE deps.

[alilee]

Thanks for the comment.. will think about what I can do.

[kubek2k]

@alilee the cheshire is added to classpath implicitly - my way to go was to explicitly add repl deplendencies as stated here: http://docs.lighttable.com/#connect-to-an-nrepl-server?

but, I've added exclusion for jackson:
