'Remove an item from array in groovy

The array which i have in groovy is not getting recognized. How to remove an item within an array based on condition

If this is my array

def list = [   
  [prerelease: 'true',  surname: 'surname'],
  [prerelease: 'true',  surname: 'surname'],
  [prerelease: 'false', surname: 'surname']
]

list.removeAll(list.findAll{it.prerelease == 'true'})
println list

I get the following output

[[prerelease:false, surname:surname]]

If my array is in this format

def list1 = [   
  {prerelease: 'true',  surname: 'surname'},
  {prerelease: 'true',  surname: 'surname'},
  {prerelease: 'false', surname: 'surname'}
]

Then i get the following error

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/home/cg/root/2646066/main.groovy: 2: unexpected token: true @ line 2, column 16.
     {prerelease: 'true',  surname: 'surname'},

I need to make the list1 work. Is there anyway it will work in groovy if my array is in the above format with "{" parenthesis

List1 is an output from bash hence it's in this format. I need to use this array in groovy to remove some items from array. Bash script to generate the array is called from groovy. Output of that bash script returns an array like this.

Idk the exact output that you want. But this code is what I understand

def list = [   
  [prerelease: 'true',  surname: 'surname'],
  [prerelease: 'true',  surname: 'surname'],
  [prerelease: 'false', surname: 'surname']
]

def newList = []
list.each { value ->
 if(value.prerelease == 'true') {
  list.remove(value.prerelease)
 } else {
  newList.add(value)
 }
}
println newList

Output

[[prerelease: 'true',  surname: 'surname'],[prerelease: 'true',  surname: 'surname']]
