Jenkins/Job DSL, Pipelines, JaaC

Example - explained line by line

job("Demo build job") { scm { git { remote { url 'https://github.com/lexandro/restapi-demo.git' } branch 'master' shallowClone true } } steps { maven('compile') } }

In this line we are defining the closure as job and specifying the name. The name is mandatory! Here's the definition start for version controller configuration We are using git. Defining the remote endpoint for git. Specifying the URL of the repository Closing the block We are operation only on the master branch at the moment To speed up the checkout process we are using shallow cloning. closing block the definition of the checkout part is done Start the definition of build steps block we are using maven to compile the code as demonstration

Example - groovy variable substitution and for.each

def owner = 'integrations'
def project = 'jenkins-dsl'
def branchApi = new URL("https://api.github.com/repos/${owner}/${project}/branches")
def branches = new groovy.json.JsonSlurper().parse(branchApi.newReader())
branches.each {
  def branchName = it.name
  def jobName = "${owner}-${project}-${branchName}".replaceAll('/','-')

              github("${owner}/${project}")

    }
    triggers {
        scm('*/15 * * * *')
    }
    steps {
        shell('ls -l')
    }
