Jenkins. Как получить значение из ERROR?

Question

[Syrex]

Установлено Jenkins 2.89.4 + Pipeline плагины

Код пайплайна:

pipeline{
    agent any
    stages{
        stage('INIT'){
            steps{
                script{
                    error 'My Error in Stage'
                }
            }
        }
    }
    post{
        success {
            echo "post success"
        }
        failure{
            echo "post failure"
        }
    }
}

В логе Jenkins видим следующие строки:

Running in Durability level: MAX_SURVIVABILITY
[Pipeline] node
Running on Jenkins in d:\tmp\JenkinsWS\TEST
[Pipeline] {
[Pipeline] stage
[Pipeline] { (INIT)
[Pipeline] script
[Pipeline] {
[Pipeline] error
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Post Actions)
[Pipeline] echo
post failure
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
ERROR: My Error in Stage
Finished: FAILURE

Вопрос: как получить в post.failure блоке значение My Error in Stage
