Up until upgrading to 2.17 I could reference my build parameters (from "This build is parameterized" section). Now these parameters are silently replace with empty strings when the promotion is run automatically after the build.
If I run the promotion again, it works.
From the promotion job:
I logged the env for a promotion run immediately after and one run later manually.
For the immediate case, all my parameters above, CONFIG, RELEASES are null whereas they are correct for the later manual invocation.
Note that promoted builds specific parameters are OK, it's just all the rest that are not.
What makes this worse is that the jenkins updater doesn't offer a downgrade option for this plugin.
