Use environment variable in parameter section of Jenkins pipeline

Question

I have an environment variable which represents a gitrepo and I use this repo in my git parameter:

pipeline { agent any options { buildDiscarder(logRotator(numToKeepStr: '5', artifactNumToKeepStr: '1')) disableConcurrentBuilds() } environment { GitRepo = 'https://my-repo/repo.git' } parameters { gitParameter branchFilter: 'origin/(.*support.*)', defaultValue: 'develop', name: 'SUPPORTBRANCH', type: 'PT_BRANCH', useRepository: env.GitRepo , sortMode: 'DESCENDING_SMART' } ...}

When I use env.GitRepo inside the stages of my pipeline it works, but not when I use it in a parameter section.

How can I make this work?

Does it really need to be an environment variable? If not a simple property could do the trick. Of course you can still use it to define the environment variable if required...

I used a string parameter just because for me it seemed too difficult to get a simple example running using the gitParameter plugin. But of course you can use the property also for the git parameter plugin.

// simply define the property here... gitRepo = 'https://my-repo/repo.git' pipeline { agent any environment { // optional, not used below. Use only if you need to have an environment variable GitRepo = gitRepo } options { buildDiscarder(logRotator(numToKeepStr: '5', artifactNumToKeepStr: '1')) disableConcurrentBuilds() } parameters { string defaultValue: gitRepo, description: '', name: 'Test', trim: false } stages { stage ('foo') { steps { echo 'Hi' } } } }
