Build Flow Plugin: How to get possible parameter values from Job

[Elias Kirchgässner]

I' ve got a job which deploys the software to different customers. CUSTOMER  has e.g 4 options C1, C2, C3

Now I want to trigger a build for each of them with build flow plugin.

Pseudo code:

def customers=job("Deploy").getParameter(1).getOptions()
foreach(customer in customers){
build("Deploy", param1:customer)
}

Is it possible to get the possible options of a parameter from a job?
