How to get all parameters(Parameterized build) from jenkins pipeline?

Question

I am building one Parameterized pipeline job in newer version of jenkins.In older version of jenkins i have used getbinding().getVariables() to retrieve all parameters. But newer version it is return null values. How to retrieve parameters(all) in newer version of jenkins?

Answer 1

You can access parameters using "params" variable.

params.each {param ->
  println "${param.key} -> ${param.value} "
}

Answer 2

For string parameters, call trim(). Modifying @Jayan's example:

params.each {param ->
  println " '${param.key.trim()}' -> '${param.value.trim()}' "
}
