Substitute variable in an array from another array

Question

Using groovy, how can I substitute the value of an array in another array variable?

For eg.:

def Env = [
    'Env1',
    'Env2',
    'Env3'
]

def Job = [
 [
    name: "Job1",
    label: "<$Env>",
    action: #!/usr/bin/bash
             blah
             blah          
 ],
 [
    name: "Job2",
    label: "<$Env>",
    action: #!/usr/bin/bash
             blah
             blah
 ]

]

I want the label field in the second array Job to be populated by every item in Env

Your code above should do that https://groovyconsole.appspot.com/script/5170432558759936 — Mike W, May 23 '17 at 09:44
It is substituting $Env with all values in Env at once, I want it to do it one at a time, first Env1 and then Env2 and so on — Innocentspirit, May 23 '17 at 10:25
I want Job1 and Job2 to first have Env1 and then Job1 and Job2 to have Env2 and so on until it gets to the end of all Envs. Hope this makes sense — Innocentspirit, May 23 '17 at 11:15

If the code isn't dynamic you can just do:

def Env = ['Env1','Env2', 'Env3']

def Job = [  
[     
    name: "Job1",     
    label: "<${Env[0]}>",     
    action: '#!/usr/bin/bash'
],  
[     
    name: "Job2",     
    label: "<${Env[1]}>",     
    action: '#!/usr/bin/bash'
]
]

If it's dynamic you can do:

Job.eachWithIndex{ obj, idx ->
    obj.label = Env[idx]
}
