Get Log for each Jenkins pipeline stage

Question

Anyone know how I can get the separate logs (for each pipeline stage) as the Blue Ocean shows. I need to attach them to Jira but I can not find them. Any idea?

Answer 1

you can find the rest api document through this url:

https://github.com/jenkinsci/blueocean-plugin/tree/master/blueocean-rest

still need to notice this in their document.

The Blue Ocean REST API is a "private API" designed for the Blue Ocean user interface. 
It may change without notice at any time.

Answer 2

I'm doing the same thing with the global pipeline library I'm building. This is good for cases where you just want to email the logs of a particular failed stage. Here's how hope it helps. On the sample pipeline below a job named test is executed once (build #1)

    pipeline {
        agent any
        stages{
            stage("Compile") {
                steps {
                    script {
                        echo "Compiling..."
                    }
                }
            }
            stage("Test") {
                steps {
                    script {
                        echo "Testing..."
                    }
                }
            }
            stage("Build") {
                steps {
                    script {
                        echo "Building..."
                    }
                }
            }
        }
    }
    

1. Access the API to see execution details. Notice that each object of this JSON includes the attributes id and result. http://localhost:8080/blue/rest/organizations/jenkins/pipelines/test/runs/1/nodes/

           "causeOfBlockage": null,
           "edges": [],
           "firstParent": "15",
           "restartable": true
       }
   ]
   

2. Use result to check the status of a stage (SUCCESS, FAILED, ABORTED, etc...)

3. Use id to get into a particular stage, for this example the logs of Test stage which has an id of 15.
