Passing parameters to corb uri stage using ml-gradle

I'm using ml-gradle with corb2 2.4.5 and Marklogic 9.0.5.

I'm trying to pass a parameter to corb when running the gradle task. I've passed the parameter in at

-DURIS-MODULE.id="sf"

In my xquery module, I have

declare variable $id as xs:string external;

The corb process runs, but it doesn't set the id variable. What do I need to change to make this work?

All system properties should be set and passed to your CoRB job when executing the ml-gradle CoRB task.

I suspect that you might be running an old version of ml-gradle, or there may be something else that is off in your job.

I have verified that I can pass in an external URIS-MODULE variable to this simplified job by executing the following command:

gradle -DURIS-MODULE.id=2 -DURIS-MODULE="INLINE-XQUERY|declare variable $id external;concat('PROCESS-MODULE.id=',string($id)),1,1|ADHOC" -DPROCESS-MODULE="INLINE-XQUERY|declare variable $id external;xdmp:log(concat('process module id=',$id))|ADHOC" corb

and I see that my application servers error log includes the line:

2020-03-12 09:23:44.198 Info: process module id=2

The ml-gradle CoRB task collects all system properties and passes them to CoRB when the task runs:

https://github.com/marklogic-community/ml-gradle/blob/master/src/main/groovy/com/marklogic/gradle/task/CorbTask.groovy#L102

Map options = buildCorbOptions()
//CoRB2 will evaluate System properties for options
systemProperties(options)

super.exec()

The buildCorbOptions() method https://github.com/marklogic-community/ml-gradle/blob/master/src/main/groovy/com/marklogic/gradle/task/CorbTask.groovy#L121

  /**
  * Construct CoRB2 options from the following sources:
  * task variables - lowerCamelCase names that correspond to their CoRB2
  *                  option (i.e. optionsFile => OPTIONS-FILE)
  * project properties - Project properties with the naming convention
  *                      of a 'corb' prefix and CamelCased CoRB2 option name
  *                      (i.e. corbOptionsFile => OPTIONS-FILE)
  * System properties - Any System property with a CoRB2 option name
  *
  * If properties are defined in more than one place, System properties will take
  * precedence over Project properties, which take precedence over task member variables.
  *
  * @return Map of CoRB2 options
  */
  public Map buildCorbOptions() {
    //first, convert legacy task properties and generate options from conventions
    Map options = collectNormalizedOptions()
    //collect all of the corb task options (i.e. threadCount=12)
    options << collectMemberVariables()
    //apply any corb project properties (i.e. -PcorbThreadCount=12)
    options << collectCorbProjectProperties()
    //apply any CoRB2 System properties (i.e. -DTHREAD-COUNT=12)
    options << collectSystemProperties()
    options //return the merged options
  }

invokes the collectSystemProperties() method:

  /**
  * Collect all System.properties. This allows for any CoRB option to be set, including those not statically known such
  * as CoRB custom inputs (e.g. URIS-MODULE.foo, PROCESS-MODULE.bar, etc) as well as settings for other libraries, such
  * as xcc.httpCompliant to enable XCCS compatability for XCC.
  * @return all System.properties

  public Map collectSystemProperties() {
    System.properties
