`java.lang.IllegalArgumentException: wrong number of arguments` when calling `s3transfer/upload`

[p-himik]

(s3t/upload credentials
            :bucket-name bucket-name
            :key key
            :input-stream stream
            :object-metadata {:content-type   content-type
                              :content-length content-length})

results in

Internal Error 
java.lang.IllegalArgumentException: wrong number of arguments

I think the issue is that amazonica.core/best-method does not distinguish between methods that accept one bean and methods that accept multiple beans. In this case, it has chosen TransferManager.upload(PutObjectRequest,S3ProgressListener) when it should've chosen TransferManager.upload(PutObjectRequest) instead.

workaround is

(require '[amazonica.core :as amz])

(amz/with-credential credentials
  (s3t/upload :bucket-name bucket-name
              :key key
              :input-stream stream
              :object-metadata {:content-type   content-type
                                :content-length content-length}))

The workaround doesn't seem sufficient. I'm getting the same error with many attempted permutations of using a map or inline keys and values or using with-credential or not. Sometimes when I get a failure to compile during lein test, I can get a success just by running lein test again immediately. I also sometimes throw in a lein clean with no clear recipe allowing code exactly like the workaround to compile on repeated trials such that it will run (or not) consistently.

@scgilardi I ended up using positional arguments:

(s3t/upload (get-auth)
            (get-bucket-name bucket-kind) key
            (io/input-stream content) {:content-type   content-type
                                       :content-length (count content)})

@p-himik That worked great. Thank you very much!

I saw this today in our code and liked the refinement of including commented out keys to get most of the benefit the non-positional calling convention while working around this undesired behavior.
