java.lang.NoSuchMethodError: No such DSL method 'readJSON'

Question

def data = readJSON text: '{"rel" : {"configVersion": "1.0","manifest" :"'+"${manifestURL}"+'"}}'
writeJSON(file: 'C:\\Users\\Public\\json\\config.json', json: data)

I am using JSON function in my Jenkins pipeline and getting NoSuchMethodFoundError. I am using Jenkins 2.85.

Any idea how to resolve this issue?

Solution 1

Using Pipeline Utility Steps Plugin you can use the readJSON function.

def props = readJSON text: '{ "key": "value" }'

You can not use this function without this plugin.

Solution 2

Install the Pipeline Utility Steps plugin.

Solution 3

And in my case it was just a stupid typo: readJson instead of readJSON.
