Reusing groovy script in jenkins Declarative pipeline file

Is there a way to reuse groovy script loaded once in Jenkinsfile.

Right now this is what I am doing

            steps {
                script {
                    def util = load("${env.WORKSPACE}/scripts/build_util.groovy")
                    util.runStep1()
                }
            }
            steps {
                script {
                    def util = load("${env.WORKSPACE}/scripts/build_util.groovy")
                    util.runStep2()
                }
            }
            steps {
                script {
                    def util = load("${env.WORKSPACE}/scripts/build_util.groovy")
                    util.runStep3()
                }
            }

I am doing the same again in post build with multiple script blocks step to send mails.

Is there a better way to do this? I cannot use shared libraries.

Yes, you just need to load the script only once.

def util = load("${env.WORKSPACE}/scripts/build_util.groovy")

You can create a stage and load the script there and store in a variable and then do something like this:-

stage('Environment') {
     agent  { node { label 'master' } }
        steps {
          script {
                def util = load("${env.WORKSPACE}/scripts/build_util.groovy")
               }
            }
         }
post {
        // Things that we want done regardless of pipeline's outcome
        //
        always {

            // Push the overall statistics from all the stages to InfluxDB
            //
            node (LINUX_BUILD_NODE){
                script{
                    //Mail sending function call
                    //
                    util.runStep1()
                    util.runStep2()
                    util.runStep3()                        
                }
            }
        }
    }

You can use "util" in any stage to call the different functions.

You can declare the variable util at top level, then assign value to it in the first stage, after than you can use it in any stage.

def util;

pipeline {
   agent any
   stages {
      stage('one') {
        steps {
            script {
                util = load("${env.WORKSPACE}/scripts/build_util.groovy")
                util.runStep1()
            }
        }
      }
      post {
        util.xxxx
      }

      stage('two') {
        steps {
            script {
                util = load("${env.WORKSPACE}/scripts/build_util.groovy")
                util.runStep2()
            }
        }
      }
      post {
        util.xxxx
      }

   }

   post {
        util.xxxx
   }
}
