I'm trying to use rundeck to promote builds from Jenkins.

I'm using Jenkins version 1.452 and rundeck plugin version 2.11

To make the promotion seamless I'm trying to use the artifact variables to grab the name of the last artifact built but I get no options back.

I've tried both via the build url:

http://JENKINS:8080/plugin/rundeck/options/artifact?project=<jenkins project name>

And by passing the options from jenkins:
warname=$ARTIFACT_NAME

The url returns an empty array:

[]

Passing the options returns:

%7B.*.war%7D

Let me know if there is any extra information required.

Thanks,
Pierre
