Parallel Deploys to multiple ElasticBeanstalk Applications / Environments

[thesmith]

If you try to do a parallel deploy to multiple ElasticBeanstalk Applications / Environments then only one artefact gets replicated across all those environments :(

Because this line uses the commit ID and the date/time, and does not include the artefact / environment name, while the artefacts can be built from different folders, they will resolve to the same S3 object. That will then be deployed everywhere.

Sometimes you'll get lucky and the second will be different, but I'm not that lucky.
