Is there a way to provide Jenkins parameter(in string form) instead of expected int value in fields?

[Bob-theUnityBuilder]

Hi,

I see that Jenkins allows evaluation of strings at run time in lieu of providing integers in some fields.

One such place is copy artifact. I've created a pipeline job and I'm passing a paramter XYZ assigned with Build Number of upstream job to a job downstream. I tried to use the copyArtifacts(...) as follows - 

steps{
 copyArtifacts(downstreamUnityJob.name,"target/**"){
   buildNumber("\$UNITY_BUILD_NUMBER")
 }
}

I get an error  - 

groovy.lang.MissingMethodException: No signature of method: static javaposse.jobdsl.dsl.helpers.StepContext.buildNumber() is applicable for argument types: (java.lang.String) values: [$UNITY_BUILD_NUMBER]

which is perfectly valid according to this code -

 https://github.com/jenkinsci/job-dsl-plugin/blob/master/job-dsl-core/src/main/groovy/javaposse/jobdsl/dsl/helpers/step/CopyArtifactContext.groovy

So my question is, is there a way to pass evaluation parameters such as above to functions that don't accept them? 

If anyone knows any other way to handle this please let me know.

Thanks.

That's most like a bug in CopyArtifactContext's buildNumber method signature. File a JIRA or a Pull Request.

Is it possible to use a work around to change the value of the build number after the XML has been created? Curious as I want to get up and running as quickly as possible.

Thanks,

You can change it in the configure block like:

job {

  name 'test'

  steps{

   copyArtifacts('xxx','target/**'){

     buildNumber(0)

   }

  }

  configure { project ->

    project /

      builders / 

      'hudson.plugins.copyartifact.CopyArtifact' / 

      selector / 

      buildNumber('$UNITY_BUILD_NUMBER')

  }

}

Awesome, many thanks. I've also submitted a PR to get the origin issue fixed without the need to use the workaround.
