Groovy code in script block to replace general build step step() - jenkins

Question

Among the possible steps one can use in a Jenkins pipeline, there is one with the name step, subtitled General Build Step. https://www.jenkins.io/doc/pipeline/steps/workflow-basic-steps/#step-general-build-step . I need to iterate on calling this step based on the contents of a file. I have created a groovy script to read the file and perform the iteration, but I am not sure how to create the equivalent of my step() in the groovy script. Here is the general format of the step I am trying to perform:
stage ('title') {
steps {
step([
$class: 'UCDeployPublisher',
siteName: 'literal string',
deploy: [
$class: 'com.urbancode.jenkins.plugins.ucdeploy.DeployHelper$DeployBlock',
param1: 'another literal string',
param2: 'yet another string'
]
])
}
}
The script step I have developed looks like this:
steps {
script {
def content = readFile(file:'data.csv', encoding:'UTF-8');
def lines = content.split('\n');
for (line in lines) {
// want to insert equivalent groovy code for the basic build step here
}
}
}
I'm expecting there is probably a trivial answer here. I'm just out of my element in the groovy/java world and I am not sure how to proceed. I have done extensive research, looked at source code for Jenkins, looked at plugins, etc. I am stuck!

Answer 1

Check the following, simply move your UCDeployPublisher to a new function and call that from your loop.
steps {
script {
def content = readFile(file:'data.csv', encoding:'UTF-8');
def lines = content.split('\n');
for (line in lines) {
runUCD(line)
}
}
}
// Groovy function
def runUCD(def n) {
stage ("title $n") {
steps {
step([
$class: 'UCDeployPublisher',
siteName: 'literal string',
deploy: [
$class: 'com.urbancode.jenkins.plugins.ucdeploy.DeployHelper$DeployBlock',
param1: 'another literal string',
param2: 'yet another string'
]
])
}
}
}

This is showing the code related to my comment on the accepted answer
pipeline {
stages {
stage ('loop') {
steps {
script {
... groovy to read/parse file and call runUCD
}
}
}
}
}
def runUCD(def param1, def param2) {
stage ("title $param1") {
step([
....
])
}
}
