I use Jenkins Pipeline with "Pipeline Script from SCM".

In my pipeline script, there is a parameters definition. When I change the parameters in my Jenkinsfile and push the changes to my SCM, the new parameters are not shown up in Jenkins when I click "build with parameters". I have to run the job once with the old configuration and afterwards the new parameters show up.

It would be great if you can provide a possibility to "reload" the Pipeline script (with its new parameters) from scm without executing the Job, e.g. adding a button "reload Jenkinsfile".
