(update below)
I have a declarative pipeline job which can take an argument VERSION.
pipeline {
parameters {
string(name: VERSION, defaultValue: '')
}
// ...
}
If no VERSION is given, like when Gitlab send a hook to this job, I want to compute it from git, so I do something like this
stages {
stage('Prepare') {
steps {
// ...
if (! env.VERSION) {
VERSION = sh(script: "git describe", returnStdout: true).trim()
}
}
}
}
Now I want to "inject" this variable to
I tried changing above code with
stages {
stage('Prepare') {
steps {
// ...
if (! env.VERSION) {
env.VERSION = sh(script: "git describe", returnStdout: true).trim()
}
}
}
}
Got this error groovy.lang.MissingPropertyException: No such property: VERSION for class: groovy.lang.Binding
I then tried to add a "environment" step below
environment {
VERSION = ${VERSION}
}
but it didn't solve my problem.
I'm looking for any help to solve it.
UPDATE
I now have a working pipeline which looks like
pipeline {
agent any
parameters {
string(name: 'VERSION', defaultValue: '')
}
environment {
def VERSION = "${params.VERSION}"
}
stages {
stage('Prepare & Checkout') {
steps {
script {
if (! env.VERSION) {
VERSION = sh(script: "date", returnStdout: true).trim()
}
echo "** version: ${VERSION} **"
}
}
}
stage('Build') {
steps {
// sh "./build.sh"
echo "** version2: ${VERSION} **"
}
}
} // stages
post {
always {
mail to: '[email protected]',
subject: "SUCCESS: ${VERSION}",
body: """<html><body><p>SUCCESS</p></body></html>""",
mimeType: 'text/html',
charset: 'UTF-8'
deleteDir()
}
}
} // pipeline
I needed to add the "environment" step to be able to get $VERSION in all Stages (not only in the one it is manipulated).
I still need to find a way to inject this $VERSION variable in the environment variables, so that my build script can find it.

If you want to inject the variable in the environment so that you can use it later, you could define another variable that is equal to env.VERSION or the output of the shell scrip. Then use that variable in your pipeline eg:
pipeline {
parameters {
string(name: VERSION, defaultValue: '')
}
def version = env.VERSION
stages {
stage('Prepare') {
steps {
// ...
if (!version) {
version = sh(script: "git describe", returnStdout: true).trim()
}
}
}
mail subject: "$version build succeeded", ...
}
If you want other jobs to be able to access the value of VERSION after the build is run, you can write it in a file and archive it.
Edit: In order for your script to be able to use the version variable, you can either make your script take version as a parameter or you can use the withEnv step.
