How to force jenkins to reload a jenkinsfile?

Question

My jenkinsfile has several paremeters, every time I make an update in the parameters (e.g. remove or add a new input) and commit the change to my SCM, I do not see the job input screen updated accordingly in jenkins, I have to run an execution, cancel it and then see my updated fields in

properties([   parameters([     string(name: 'a',       defaultValue: 'aa',     description: '*', ),     string(name: 'b',   description: '*', ),     string(name: 'c',       description: '*', ),    ]) ]) 

any clues?

One of the ugliest things I've done to get around this is create a Refresh parameter which basically exits the pipeline right away. This way I can run the pipeline just to update the properties.

pipeline {     agent any     parameters {         booleanParam(name: 'Refresh',                     defaultValue: false,                     description: 'Read Jenkinsfile and exit.')     }     stages {         stage('Read Jenkinsfile') {             when {                 expression { return parameters.Refresh == true }             }             steps {                 echo("Ended pipeline early.")                     }         }         stage('Run Jenkinsfile') {             when {                 expression { return parameters.Refresh == false }             }             stage('Build') {                 // steps             }             stage('Test') {                 // steps             }             stage('Deploy') {                 // steps             }         }     } } 

There really must be a better way, but I'm yet to find it :(

Unfortunately the answer of TomDotTom was not working for me - I had the same issue and my jenkins required another stages unter 'Run Jenkinsfile' because of the following error:

Unknown stage section "stage". Starting with version 0.5, steps in a stage must be in a ‘steps’ block.

Also I am using params instead of parameters as variable to check the condition (as described in Jenkins Syntax).

pipeline {     agent any     parameters {         booleanParam(name: 'Refresh',                     defaultValue: false,                     description: 'Read Jenkinsfile and exit.')     }     stages {         stage('Read Jenkinsfile') {             when {                 expression { return params.Refresh == true }             }             steps {               echo("stop")             }         }         stage('Run Jenkinsfile') {             when {                 expression { return params.Refresh == false }             }             stages {               stage('Build') {                   steps {                     echo("build")                   }               }               stage('Test') {                   steps {                     echo("test")                   }               }               stage('Deploy') {                   steps {                     echo("deploy")                   }               }             }         }     } }
