How to use Jenkinsfile in pipeline builds?

[Mark Allison]

I have a pipeline build and I want to move it to source control. I've copied out the script from the the project into a Jenkinsfile and added it to git. In my pipeline I have code like this:

#!groovy​
node {

        stage('checkout') {

            deleteDir()
            git 'http://git.server/markallison/my-project.git'
        }
       
        stage('build') {
            // build code


            }    

   

... etc

I like to have a clean workspace every time the build runs, so how do I do this without having to have a separate project for my Jenkinsfile?

Actually this works fine, ignore. I had misconfigured something.
