How to trim parameters in Jenkins pipeline?

Question

I am setting up a parameterized Jenkins job with pipeline. I need to trim trim parameters any suggestions?

In New version of Jenkins i can able to get the parameters. But I can't modify the parameters. If i use setValue(), it gives me unsupportedException.

Answer 1

parameters {
        string(defaultValue: "", description: '', name: 'tag or commit', trim: true)
}

Answer 2

Which type of parameter are You using? Is it user input or some kind of choice list? As workaround You can use another variable:

myVar = param1.trim() 

then You can use myVar instead o param1
