Can't check a object is null inside a jenkins pipeline, this should work in groovy but does not work in a jenkins pipeline
Apologies if I have logged this in the wrong place or if this is not possible in a jenkins pipeline
Pipeline
pipeline {
agent any
stages {
stage('Test') {
steps {
script {
def data = readYaml text: """
builds:
test:
parameters:
booleanParam:
FOO: 'true'
test2:
"""
if ( data.get('builds').get('test2').get('parameters') != null ) {
echo "test2 params exist"
} else {
echo "test2 params DONT exist"
}
}
}
}
}
}
