Access Stage name during the build in Jenkins pipeline

You can now do this in a built-in manner, since Jenkins 2.3. Like so:

steps {    updateGitlabCommitStatus name: STAGE_NAME, state: 'running'    echo '${STAGE_NAME}'}

For more information see: https://issues.jenkins-ci.org/browse/JENKINS-44456

This should work from a pipeline shared library:

#!/usr/bin/env groovyimport hudson.model.Action;import org.jenkinsci.plugins.workflow.graph.FlowNodeimport org.jenkinsci.plugins.workflow.cps.nodes.StepStartNodeimport org.jenkinsci.plugins.workflow.actions.LabelActiondef getStage(currentBuild){    def build = currentBuild.getRawBuild()    def execution = build.getExecution()    def executionHeads = execution.getCurrentHeads()    def stepStartNode = getStepStartNode(executionHeads)    if(stepStartNode){        return stepStartNode.getDisplayName()    }}def getStepStartNode(List<FlowNode> flowNodes){    def currentFlowNode = null    def labelAction = null    for (FlowNode flowNode: flowNodes){        currentFlowNode = flowNode        labelAction = false        if (flowNode instanceof StepStartNode){            labelAction = hasLabelAction(flowNode)        }        if (labelAction){            return flowNode        }    }    if (currentFlowNode == null) {        return null    }    return getStepStartNode(currentFlowNode.getParents())}def hasLabelAction(FlowNode flowNode){    def actions = flowNode.getActions()    for (Action action: actions){        if (action instanceof LabelAction) {            return true        }    }    return false}def call() {    return getStage(currentBuild)}

Example usage:

node {    stage('Stage One'){        echo getCurrentStage()    }    stage('Stage Two'){        echo getCurrentStage()    }}

Aleks' workaround works fine, just thought it's worth sharing the code

node ("docker") {    def sendOk = {        String stage -> slackSend color: 'good', message: stage + " completed, project - ${env.JOB_NAME}:1.0.${env.BUILD_NUMBER}"    }    def sendProblem = {        String stage, error -> slackSend color: 'danger', message: stage + " did not succeed, project - ${env.JOB_NAME}:1.0.${env.BUILD_NUMBER}, error: ${error}, Find details here: ${env.BUILD_URL}"    }    def exec = {        work, stageName ->             stage (stageName) {                try {                    work.call();                    sendOk(stageName)                }                catch(error) {                    sendProblem(stageName, error)                    throw error                }            }    }    exec({        git credentialsId: 'github-root', url: 'https://github.com/abc'        dir ('src') {            git credentialsId: 'github-root', url: 'https://github.com/abc-jenkins'        }        sh "chmod +x *.sh"    }, "pull")    exec({ sh "./Jenkinsfile-clean.sh \"1.0.${env.BUILD_NUMBER}\"" }, "clean")    exec({ sh "./Jenkinsfile-unit.sh \"1.0.${env.BUILD_NUMBER}\"" }, "unit")    exec({ sh "./Jenkinsfile-build.sh \"1.0.${env.BUILD_NUMBER}\"" }, "build")    exec({ sh "./Jenkinsfile-dockerize.sh \"1.0.${env.BUILD_NUMBER}\"" }, "dockerize")    exec({ sh "./Jenkinsfile-push.sh \"1.0.${env.BUILD_NUMBER}\"" }, "push")    exec({ sh "./Jenkinsfile-prod-like.sh \"1.0.${env.BUILD_NUMBER}\"" }, "swarm")}
