Hi, I'm getting this error with 0.13.0 version.
It seems to work(or at least sbt doesn't complain) when downgrading to version 0.12.0.
Any ideas what can it be?

Hi @sparrovv! It should be related to the Java version. Which Java do you use? And which version of this plugin. Also, if you try it with sbt 0.13, then it should be 0.13.5+, because there are some changes related to autoplugins..

HI @laughedelic

% java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)

% sbt --version
sbt launcher version 0.13.7

As I mentioned before, I got that exception in 0.13.0.
0.12.0 works fine.

Thanks!

Hey @sparrovv
I've just published a snapshot version, could you try it and tell me if you still have this exception? For that you need to add another resolver:

resolvers += "Era7 maven snapshots" at "https://s3-eu-west-1.amazonaws.com/snapshots.era7.com"

addSbtPlugin("ohnosequences" % "sbt-s3-resolver" % "0.14.0-SNAPSHOT")

Hey @laughedelic, looks like that version solved my problem. Thanks!
I'm not getting that exception any more, and I was able to publish a jar.

One thing tough. I'm not sure if that has changed in the version 0.13.0, but I initially got:
com.amazonaws.AmazonClientException: Unable to load AWS credentials from any provider in the chain

I think version 0.12.0 was picking up my AWS env variables, and 0.14.0 checks ~/.aws/credentials file, where I initially didn't have a default profile.

Good! Actually, I just recompiled the ivy-s3-resolver with java 1.7 (our default now is 1.8). I'm going to release 0.13.1 here.

About credentials, yes, 0.13.0 looks up only in two places: default profile (or whichever you setup) and instance role credentials. But that's a good point about env variables. I can change it to the DefaultAWSCredentialsProviderChain in the next version if you think it's worth it 😉

Setting version to 0.13.1:
50f6a1d 
- Updated ivy-s3-resolver to 0.7.1. It solves the Java incompatibility issue [#38](#38).

I know a few people who use env variables instead of aws/credentials, so I guess it would be easier for them.

Ok. Done in 646df35, will be in the next release.
