Define global environment variables from inside a stage

I have env vars defined in my environment directive at the top of the pipeline:

environment {
    var1 = 'sdfsdfdsf'
    var2 = 'sssssss'
}

But there are some that I need to dynamically set or override in the stages. But if I use an environment{} directive in a stage the vars won't be accessible to other stages. Initially I thought I could define them all with default values in the top environment directive and overwrite them in the pipeline but this is the behavior I observed:

  1. Define var in environment block
  2. Try to overwrite in script{} block like: script {env.var1 = 'new value'}
  3. The env is not overwritten

How can I change the envs?

You can do it as follow:

  1. Define var in stage environment { env.var1 = 'value' }

  2. you can access same var in other stages and change value in environment { env.var1 = 'value2' }

     pipeline {
  agent any
  environment { 
     var1 = 'value'
  }

  stages {
     stage('Initialize') {
       steps {
        script {
        echo ("value : " + env.var1)
         }
       }
    }

    stage('build') {
      environment { 
        var1 = 'value2'
       }
       steps {
        script {
          echo ("value : " + env.var1)
        }
      }
    }
  }
}
