Answer 1

def jenkins = hudson.model.Hudson.instance
def template = jenkins.getItem("MyTemplate")
def job = jenkins.copy(template,"MyNewJob")
job.save()

I used this now I have to change the parameter values of MyNewJob using Groovy how will I do that?

ex I have a parameter called "Build_BranchName" and the default is //perforce/mybranch I have to change it to //perforce/mynewbranch
