When using multiple outputs the order the outputs are processed in doesn't match the order they're defined in the UI. I've found this occur with three outputs, though I could have just been lucky with two outputs.

The two attachments show the order in the pipeline and in the Jenkins job. When the job is executed, the log contains the following (emphasis mine):

08:20:06 [AWS CodePipeline Plugin] Uploading artifact: {Name: ReqMgrLog,Location: {Type: S3,S3Location:

{BucketName: ###, ObjectKey: EOT/ReqMgrLog/vDtEgfa}

What's worse is that I have three jobs set up in this way, and in each case the outputs are picked up in a different order.
