I have the following jenkinsfile

pipeline {
    agent any
    environment {
        VERSION=""
    }
    stages {
        stage ("release"){
            steps {
                script {
                    ${VERSION}=sh(returnStdout: true, script:$("./bashscript.sh).trim())
                }
            }
        }
}

What I'm trying to do is simple, I want to call to bash file that return a value to environment variable in my jenkinsfile.

I have 2 questions: 1. how to return value from bash file? 2. how to insert it to environment variable in jenkinsfile?

That's my .sh file:

# !/bin/bash
if [ some condition... ] 
then
    some commands....
    return "value"
else
    some commands....
    return "other value"
fi

I've searched for long time and found nothing, is it possible at all?

NOTE: I saw many solutions for groovy but I need it in pipeline...

CodePudding user response：

1. For setting variable example from shell for jenkins use returnStdout: true . In your script echo what you need

myVal = sh(script: ' ./myFunc.ksh ', returnStdout: true)

2. Execute functions from bash as they suppose to return a variable. To make function visible you need to source it file (import) example is below

# for point 2 
#/bin/bash
# content of your file ./myfileFunc.ksh
function myFunc {
   typeset l_in_param1="$1"
   
   if [[ $l_in_param1 == "A" ]]; then
      echo "VAL_A"  
   elif [[ $l_in_param1 == "B" ]]; then
      echo "VAL_B"   
   else
      echo "ERROR VAL" >&2
   fi
}
# source it
source ./myfileFunc.ksh

#use :
val1=$(myFunc A)
val2=$(myFunc C)

3. Script returns data to the standard and error output so you can store it in variable later by reading from there using , returnStdout: true

myVal = sh(script: ' ./myFunc.ksh ', returnStdout: true)

# content of your file ./myFunc.ksh

typeset l_in_param1="$1"
   
if [[ $l_in_param1 == "A" ]]; then
    echo "VAL_A"  
elif [[ $l_in_param1 == "B" ]]; then
    echo "VAL_B"   
else
    echo "ERROR VAL" >&2
fi


l_result1=$( ./myFunc.ksh A ) 
l_result2=$( ./myFunc.ksh C )

echo $l_result1; 
echo $l_result2;

Here l_result2 will be null as we moved error to error output
