确定Jenkins声明式管道中的失败阶段

Question

如何报告声明式管道失败的阶段？在fail块中，我想获取failureStage.name并将其报告（最终报告为松弛）。

pipeline {
    agent { label 'master'}
    stages {
        stage('Ok') {
            steps {
                echo 'do thing'
            }
        }
        stage('NotOK') {
            steps {
                sh 'make fail'
            }
        }
    }
    post {
        always {
            echo 'ok'
        }
        failure {
            echo 'Failed during Which Stage?'
        }
    }
}

PipelineVisitor是一种很好的方法。但是，如果您只想查看错误，那么利用FlowGraphTable可能会更好。

以下内容提供了每个失败步骤的映射列表，并且还遍历了下游作业。我发现它非常有用。

您将要使用共享库来避免安全沙箱警告/批准

List<Map> getStepResults() {
    def result = []
    WorkflowRun build = currentBuild()
    FlowGraphTable t = new FlowGraphTable(build.execution)
    t.build()
    for (def row in t.rows) {
        if (row.node.error) {
            def nodeInfo = [
                    'name': "${row.node.displayName}",
                    'url': "${env.JENKINS_URL}${row.node.url}",
                    'error': "${row.node.error.error}",
                    'downstream': [:]

            ]
            if (row.node.getAction(LogStorageAction)) {
                nodeInfo.url += 'log/'
            }

            for (def entry in getDownStreamJobAndBuildNumber(row.node)) {
                nodeInfo.downstream["${entry.key}-${entry.value}"] = getStepResults(entry.key, entry.value)
            }
            result << nodeInfo
        }
    }
    log(result)
    return result
}

Map getDownStreamJobAndBuildNumber(def node) {
    Map downStreamJobsAndBuilds = [:]
    for (def action in node.getActions(NodeDownstreamBuildAction)) {
        def result = (action.link =~ /.*\/(?!\/)(.*)\/runs\/(.*)\//).findAll()
        if (result) {
            downStreamJobsAndBuilds[result[0][1]] = result[0][2]
        }
    }
    return downStreamJobsAndBuilds
}
