The latest version of flexible publish plugin can no expand variables in a multiconfiguration job.
I get this error in the parent job:
Exception caught evaluating condition: [org.jenkinsci.plugins.tokenmacro.MacroEvaluationException: Unrecognized macro 'profile' in '$profile'], action = [Fail the build]
Downgrading to 0.14.1 of this plugin fixes the problem. Any version higher than 0.14.1 is broken.
I'm attaching a config.xml to this ticket.
