Hi,

When using a scripted Pipeline with a node, there is no workspace directory created until you use a Jenkins built-in step which needs to write something.

If you use plain Groovy code which write something, the workspace doesn't get created.

The following simple Pipeline proves the bug:

import groovy.json.JsonBuilder

node {
    def token = [APPS: [
        [id: 1, app_name: "${APP_NAME}", version: "${APP_VERSION}"]
    ]]
    
    stage('Cleaning workspce') {
        cleanWs()
    }

    stage('Generating the token') {
        new File("${WORKSPACE}/mep.token").write(new JsonBuilder(token).toPrettyString())
    }
}

 
java.io.FileNotFoundException: /var/lib/jenkins/workspace/foobar/mep.token (Aucun fichier ou dossier de ce type)
 

I'm not sure if it's a bug or if the documentation is wrong, but to me, it's a bug.

Stating the documentation:

A workspace is automatically allocated for you with the node step
