Zendesk ticket: https://gitlab.zendesk.com/agent/tickets/14149 GitLab: 8.3.0 ## Observed Behavior After integrating Jenkins the Test Settings button will end by publishing a flash message with a content similar to: ``` We tried to send a request to the provided URL but an error occurred: undefined method ‘post’ for #<JenkinsService:0x000000006ecca88> ``` ## Expected Behavior If the configuration is correct the Test Settings button should publish a message like: ``` We sent a request to the provided URL ```` ## Error Reproduction 1. Follow the Jenkins integration steps from http://doc.gitlab.com/ee/integration/jenkins.html 2. When you get to activating the Jenkins CI service at the Project Settings area press the Test Settings button. 3. The error appears as a flash message. ## Next Steps @patricio suggested changing `self.post`to `self.class.post`which I can confirm solved this issue. ```ruby # jenkins_service.rb def execute(data) self.post( hook_url, body: data.to_json, headers: { 'Content-Type' => 'application/json', 'Authorization' => "Basic #{auth}" } ) end ```` *** /cc @JobV How should we proceed? Should I work on a MR or should we leave it to a developer for further testing?
