Not getting any output through sh alias for Jenkinsfile

Question

I have a docker container which runs Jenkins.

I have define an alias and print this alias in a jekinsfile.

I also tried manually to  connect with Jenkins container, and I did it:

alias foo='bar'
when I execute the same thing in Jenkinsfile, foo command won't respond

the pipeline code is written below:

#!/bin/groovy

pipeline {
agent any
stages {
  stage("Use alias command"){
    steps { 
        sh '''
          alias foo="bar"
          foo
        '''
    }
  }
}}

Answer 1

As you know each sh command runs in it's own shell. It has same location as agent/workspace, but since it's a new shell, environment variables, aliases, etc, can be lost.So combine the lines into a single sh:

#!/bin/groovy

pipeline {
agent any
stages {
  stage("Use alias command"){
    steps { 
        sh '''
          alias foo="bar"
          foo
        '''
    }
  }
}}
I hope it would help you resolve your query.
