Groovy Jira Rest API NoSuchFieldError: defaultRequestContentType

Question

This is my first step working with Jira Rest API and I will only return simple serverInfo

Here is my Groovy Script:

def jira = new RESTClient(JIRAURL + "/rest/api/2/");
jira.headers['Content-Type']='application/json'
jira.headers['Authorization']="Basic " + "username:password".bytes.encodeBase64().toString()
println  jira.get(path:'serverInfo')

If I execute my script I get this Exception:

java.lang.NoSuchFieldError: defaultRequestContentType
at groovyx.net.http.HTTPBuilder$RequestConfigDelegate.<init> 
(HTTPBuilder.java:989)

Can anyone help me please?

Answer 1

The error "java.lang.NoSuchFieldError" is probably because of

jira.headers[...

Have you tried to set these default headers with methods e.g.

jira.setHeaders([Content-Type: "......"])
jira.setHeaders([Authorization: "Basic ....."])

or

jira.httpClient.defaultHeaders['Content-Type'] = '...' 
jira.httpClient.defaultHeaders['Authorization'] = '...' 

The JIRA Rest call call looks fine and you can test it with Postman to check that issue is not with JIRA itself.
