I am trying to set environment variable in Jenkinsfile following way,

pipeline 
 agent label 'slave1' 

 stages 
 stage ('Build') 
 steps 
 script 
 BUILD_VERSION = sh (
 script: 'python get_firmware_version.py',
 returnStdout: true
 ).trim()
 
 echo "$BUILD_VERSION"
 withCredentials([file(credentialsId: 'image-sign', variable: 'IMAGE_SIGN')]) 
 dir('firmware/') 
 echo "$BUILD_VERSION"
 sh '''
 echo "Building"
 echo "$BUILD_VERSION"
 echo "$env.BUILD_VERSION"
 '''
 
 
 
 
 
 post 
 failure 
 script 
 echo "Pipeline Failed"
 
 
 

But its failing with following error Bad substitution

[Pipeline] echo
0_2_0
[Pipeline] sh
+ echo Building
Building
/home/jenkins/jenkins_slave/workspace/Firmware/Branch/firmware@tmp/durable-54e04481/script.sh: 3: /home/jenkins/jenkins_slave/workspace/Firmware/Branch/firmware@tmp/durable-54e04481/script.sh: Bad substitution

Why I can't set ENV Var and use it in sh step ?

This is Jenkins thing I think. When you use the sh block with '; it will not have access to things like environment variables. Try using the " instead. That should work

sh """
 echo "Building"
 echo "$env.BUILD_VERSION"
 echo "$env"
"""

Jenkins should recognise the shell block and escape the " within the """ automatically.

pipeline 
 agent label 'slave1' 

 stages 
 stage ('Build') 
 steps 
 script 
 BUILD_VERSION = sh (
 script: 'python get_firmware_version.py',
 returnStdout: true
 ).trim()
 
 echo "$BUILD_VERSION"
 withCredentials([file(credentialsId: 'image-sign', variable: 'IMAGE_SIGN')]) 
 dir('firmware/') 
 echo "$BUILD_VERSION"
 sh """
 echo "Building"
 echo "$BUILD_VERSION"
 echo "$env.BUILD_VERSION"
 """
 
 
 
 
 
 post 
 failure 
 script 
 echo "Pipeline Failed"
 
 
 

My test case

pipeline 
 agent 
 node 
 label 'devops-jenkins-slave'
 
 

 options 
 timestamps()
 

 stages 

 stage('Setup')
 steps 
 dir("$WORKSPACE/")
 script 
 BUILD_VERSION = "1"
 

 sh """
 echo "$BUILD_VERSION"
 """
 
 
 

 

 post 
 always 
 dir("$WORKSPACE/")
 deleteDir()
 
 
 

Result
