Jenkins Job DSL: Using parameters in groovyScript in job step

Question

For my build job "generated-job-1" I need several parameters, which are passed in when the build (of the generated-job-1) is triggered via URL.

Here my Job Definition with parameters inside the SeedJob DSL:

job('generated-job-1'){
label ('master')
parameters{
    stringParam('DEPLOY_URI', 'https://192.168.200.176/hyperManager', 'Provide the URL where DeploymentManager can be accessed.')
    stringParam('REG_ID', '12', 'The id of the owner (Registration) of this deployment.')
}
steps {
    groovyCommand(readFileFromWorkspace('stepscript.groovy')){
        prop('name', 'value')
        prop('DEPLOY_URI', $DEPLOY_URI)
    }
}

}

I tried to use DEPLOY_URI, $DEPLOY_URI and ${DEPLOY_URI} and it the build fails with different error messages like No such property: DEPLOY_URI for class: javaposse.jobdsl.dsl.helpers.step.GroovyContext

or ERROR: (script, line 12) No such property: $DEPLOY_URI for class: javaposse.jobdsl.dsl.helpers.step.GroovyContext

or ERROR: (script, line 12) No signature of method: javaposse.jobdsl.dsl.helpers.step.GroovyContext.$() is applicable for argument types: (script$_run_closure1$_closure3$_closure4$_closure5) values: [script$_run_closure1$_closure3$_closure4$_closure5@1a11cf0]

1. How can I define and pass those parameters to my step-script.groovy?
2. How could I use those parameters in other steps, such as shell or batchFile?
3. How do I access those parameters in my step-script.groovy, to work with the given data?

I searched for a while now and tried hard to get it working... No success.

Help really appreciated, as I am new to Job DSL and to Groovy.

Thanks in advance, Anne

You need to put the variable name in quotes so that it gets evaluated when the generated job is executed, not when the DSL script runs.

job('generated-job-1') {
    parameters {
        stringParam('DEPLOY_URI', '...', '...')
    }
    steps {
        groovyCommand(readFileFromWorkspace('stepscript.groovy')) {
            prop('DEPLOY_URI', '$DEPLOY_URI')
        }
    }
}
