to use groovy in dleclarative you have to use the `script` step to warp
your code
pipeline {
stages {
stage('Stage1') {
steps {
script { // YOU NEED TO USE THE SCRIPT BLOCK
def labels = ['machine1', 'machine2'] // labels for Jenkins node
types we will build on
def builders = [: ]
for (x in labels) {
def label = x // Need to bind the label variable before the
closure - can't do 'for (label in labels)'
// Create a map to pass in to the 'parallel' step so we can
fire all the builds at once
builders[label] = {
node(label) {
sh ''
'
echo "hostname:`hostname`"
echo "whoami:`whoami`"
''
'
}
}
}
parallel builders
}
}
}
}
}
or define a function then call it, I personally like it much is cleaner
pipeline {
stages {
stage('Stage1') {
steps {
parallelTasks()
}
}
}
}
def parallelTasks() {
def labels = ['machine1', 'machine2'] // labels for Jenkins node types we
will build on
def builders = [: ]
for (x in labels) {
def label = x // Need to bind the label variable before the closure -
can't do 'for (label in labels)'
// Create a map to pass in to the 'parallel' step so we can fire all
the builds at once
builders[label] = {
node(label) {
sh ''
'
echo "hostname:`hostname`"
echo "whoami:`whoami`"
''
'
}
}
}
parallel builders
}
