How to correctly assign a value to a variable with a path and pass it to sh?

Question

Jenkins

Hello.
During the development of the script file for jenkins, it was necessary to assign the path value to the variable in order to further pass it to sh
prepared the script

#!groovy

node('superhost01'){
    String HOSTNAME="host01"
    String USERNAME="tech_user"
    env.PATH="/data/jdbc_connector"
    stage('Prepare') {
        checkout scm
    }
    stage('Deploy') {
        sh """
        scp -r config.yaml ${USERNAME}@${HOSTNAME}:$PATH
        """
}

}

BUT when it is executed by Jenkins, the task fails by mistake in the line
env.PATH="/data/jdbc_connector"

Answer 1

correct option is to use withEnv

#!groovy

node('superhost01'){
  String HOSTNAME="host01"
  String USERNAME="tech_user"
  withEnv(['PATH=/data/jdbc_connector']) {
    stage('Prepare') {
      checkout scm
    }

    stage('Deploy') {
      sh """
      scp -r config.yaml ${USERNAME}@${HOSTNAME}:$PATH
      """
    }
  }
}
