Jenkins: 2.60.4
Master: Linux (Centos7)
Java: 1.8.141
Slave: Windows Server 2012 R2
Java: 1.8.171
Plugin: 1.8.22
We have Jenkins installed on a linux machine but have to have a particular job run on windows. We use a slave for this. One of the things this job has to do is call a REST API to test availability of a service. If I run that service on the master, it runs without an issue. When I try to run it on the slave, accessing the content through "result.content" or "result.getContent()", it throws a NullPointerException.
This is a stripped down version of the call that produces the error. Using the commented out "agent any" to have it run on the master produces the expected result. Changing to the current uncommented agent causes the error.
#!groovy def checkAvailability() { def response = httpRequest ignoreSslErrors: true, responseHandle: 'LEAVE_OPEN', url: "https://reqres.in/api/users/2", validResponseCodes: '100:599' echo "${response.content} Test" String result = response.getContent() echo "${result} Test" response.close() } pipeline { agent { label 'windows-tester' } // agent any stages{ stage("Publish") { steps { checkAvailability() } } } }
Expected Result:
[Pipeline] node Running on master in /var/lib/jenkins/workspace/httpRequestTest [Pipeline] { [Pipeline] stage [Pipeline] { (Publish) [Pipeline] httpRequest HttpMethod: GET URL: https://reqres.in/api/users/2 Sending request to url: https://reqres.in/api/users/2 Response Code: HTTP/1.1 200 OK Success code from [100‥599] [Pipeline] echo {"data":{"id":2,"first_name":"Janet","last_name":"Weaver","avatar":"https://s3.amazonaws.com/uifaces/faces/twitter/josephstein/128.jpg"}} Test [Pipeline] echo {"data":{"id":2,"first_name":"Janet","last_name":"Weaver","avatar":"https://s3.amazonaws.com/uifaces/faces/twitter/josephstein/128.jpg"}} Test [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] // node [Pipeline] End of Pipeline Finished: SUCCESS
Actual Result

Reducing priority since i found that using "responseHandle: 'STRING'" works for my use on the windows slave
