Jenkins groovy script execution for dynamic parameters

I am trying to use active choice parameters in jenkins . I am executing a shell command and trying to show the output in the choice parameters. 1) Working scenario -

Text file already generated by the output of shell command and able to see the parameters - 

list = []
def process = "cat /home/ansible/test1.txt".execute()
process.text.eachLine {list.add it}
return list

Here test1.txt is already populated with the values

2) Failure scenario Instead of pre-populating the file trying the get the shell command output and write into a file and then show it to the choice parameters- 

list = []
def process1=" sh script.sh > test1.txt".execute()
def process = "cat /home/ansible/test1.txt".execute()
process.text.eachLine {list.add it}
return list

This is not working

Is there any suggestions ?

Use pure groovy to read file lines

new File('/home/ansible/test1.txt').readLines()

For your case - wrap your code with try-catch to see the error.

Without error message it's hard to help you...

try{
  def list ....
}catch(e){ return [e.toString()] }
