Hi,

I'm new to pipeline, but I'm trying to create a job that reads in some data from JSON files, and writes it to another JSON file for future use. My script is currently written in the job definition, not a jenkinsfile

The job is choking on the writeJSON step and I don't know why. I'm basing my implementation on https://jenkins.io/doc/pipeline/steps/pipeline-utility-steps/#code-writejson-code-write-json-to-a-file-in-the-workspace

Based on the console output it seems like a library dependency hasn't been installed, but I'm not sure how to solve the issue.

Script:

pipeline {

…

stage (“Try to write a JSON file into the workspace“) {

steps {

script {

dir (‘…’) {

…

def outVersionData = lastClientData + lastAssBunsData

echo "outfile: ${outVersionData}"

writeJSON file: 'infoes.json', json: outVersionData

}

…

}

Console Output:

[Pipeline] stage

[Pipeline] { (Try to write a JSON file into the workspace)

[Pipeline] script

[Pipeline] {

[Pipeline] dir

Running in …

[Pipeline] {

…

[Pipeline] echo

outfile: [latestChangeset:14210, bundleVersionChangeset:14000]

[Pipeline] writeJSON

[Pipeline] }

[Pipeline] // dir

[Pipeline] }

[Pipeline] // script

[Pipeline] }

[Pipeline] // stage

...

java.lang.IllegalArgumentException: Could not instantiate {file=infoes.json, json={latestChangeset=14210, bundleVersionChangeset=14000}} for WriteJSONStep(file: String, json: JSON{}): java.lang.UnsupportedOperationException: must specify $class with an implementation of interface net.sf.json.JSON
