Hi, we want to run an executable against each file of a list of files, using a pool of agents (preferably specified by a label). Here's an example using both approaches: I am trying to write a function for a Jenkins pipeline that reads through the YAML file, picks up the brand, fuel and transmission value of each array set, and execute commands List all Jenkins jobs using a Groovy script. In the console log it I want to be able ro read json format based on parameter value selected in choice. Jenkins Pipeline allows you to write scripts using Groovy I have a simple groovy list in my Pipeline that adds some maps: def componentList = [] def componentMapEntry1 = [:] Navigate to the pipeline tab and add the Jenkins loop file For the pros and cons of each, refer to the comparison. One way you I have a simple input file with two words in each line and parsing in Jenkinsfile (groovy), but seeing a issue, pipeline { agent any stages { stage ('Test-1') { steps { echo ' Currently, I'm going to need an implementation that must find all files within a directory and start a parallel task for every file found. For any release, it could be 1 to 30 of those jobs that need to be run.
