[workflow] how to tell if build parameter is set?

[Craig Rodrigues]

Hi,

I tried reading: http://stackoverflow.com/questions/28572080/jenkins-workflow-how-to-access-parameters-in-a-parameterized-build/

for some ideas, but still am not sure.

I want to have a single workflow groovy file, shared across multiple

Jenkins builds.

If I have a workflow, where "this build is parameterized" is set,

how can I detect in the workflow if a particular build parameter is defined or not,

without throwing an exception?

The closest solution I found was to do this in groovy:

node {
   groovy.lang.Binding myBinding = getBinding()
   boolean mybool = myBinding.hasVariable("STRING_PARAM1")
   echo mybool.toString()
   if (mybool) {
       echo STRING_PARAM1
       echo getProperty("STRING_PARAM1")
   } else {
       echo "STRING_PARAM1 is not defined"
   }

   mybool = myBinding.hasVariable("DID_NOT_DEFINE_THIS")
   if (mybool) {
       echo DID_NOT_DEFINE_THIS
       echo getProperty("DID_NOT_DEFINE_THIS")
   } else {
       echo "DID_NOT_DEFINE_THIS is not defined"
   }
}

Is that the best way to do it, or is there a better way?
