NodeLabel parameters are null objects in pipeline script params

XMLWordPrintable

      Accessing the parameter with param will give you a null object, but accessing it through env and global will give you the string of one node.

      Example:

      properties ([
    parameters([
        [
             $class: 'BooleanParameterDefinition',
             defaultValue: false,
             description: 'This will do a clean and build of the project.',
             name: 'Rebuild'
        ],
        [
             $class: 'NodeParameterDefinition',
             allowedSlaves: ['ALL (no restriction)'],
             defaultSlaves: ['master'],
             description: 'What nodes to run the build on.',
             name: 'NODE_PARAM',
             nodeEligibility: [$class: 'AllNodeEligibility'],
             triggerIfResult: 'allowMultiSelectionForConcurrentBuilds'
        ]
    ])
])

echo "NODE_PARAM: " + NODE_PARAM.getClass().toString()
echo "env.NODE_PARAM: " + env.NODE_PARAM.getClass().toString()
echo "params.NODE_PARAM: " + params.NODE_PARAM.getClass().toString()

      Will give you this output:

      [Pipeline] echo
NODE_PARAM: class java.lang.String
[Pipeline] echo
env.NODE_PARAM: class java.lang.String
[Pipeline] echo
params.NODE_PARAM: class org.codehaus.groovy.runtime.NullObject

      As you can see, only params.NODE_PARAM is null. 

      The problem is that I can not use env.NODE_PARAM or NODE_PARAM to get multiple selection of nodes, as those are only a string representation of a single node.
