@stephenc you ride? Awesome, thanks!

@mattstep often reviews are from the proverbial "blind person on a galloping horse"... 😎 on a 🏇 is the emoji equivalent

@stephenc Ah, gotcha!

@recampbell or @stephenc can either of you merge this for me? It meets the requirements of reviewbybees I believe... I don't have permission to merge into this repo.

How are these roles exposed to Jenkins?

In my setup the plugin only defines the access key and secret variables and fails to expose the temporary token to the Jenkins job, which fails to run.

Changes without a JIRA issue associated... 😢

I don't understand either. It says it "supports roles" but there doesn't seem to be any way to get the session token. What a waste of time this plugin has turned into for me!
