Jenkins Choice parameter Passing to a pipeline Job

In script mode you can also do it like this, at the moment it is bugged and it expects the choice parameters as a newline delimited string instead of an array. When using the Pipeline and JenkinsFile in script mode you can do a quick fix like follows:

properties(
    [parameters([choice(choices: ["A", "B", "C"].join("\n"),
    description: 'Some choice parameter', 
    name: 'SOME_CHOICE')])])

You can put this before your first node statement to add parameters to your builds.

Update: example multi select with extended choice parameter plugin in Jenkins pipeline file:

com.cwctravel.hudson.plugins.extended_choice_parameter.ExtendedChoiceParameterDefinition extendedChoiceParameterDefinition = new com.cwctravel.hudson.plugins.extended_choice_parameter.ExtendedChoiceParameterDefinition(
    "OPTION_NAME", // name
    "PT_CHECKBOX", // type
    "option1,option2,option3", // values
    null, // projectName
    null, // propertyFile
    null, // groovyScript
    null, // groovyScriptFile
    null, // bindings
    null, // groovyClasspath
    null, // propertyKey
    "option1,option2", // defaultValue
    null, // defaultPropertyFile
    null, // defaultGroovyScript
    null, // defaultGroovyScriptFile
    null, // defaultBindings
    null, // defaultGroovyClasspath
    null, // defaultPropertyKey
    null, // descriptionPropertyValue
    null, // descriptionPropertyFile
    null, // descriptionGroovyScript
    null, // descriptionGroovyScriptFile
    null, // descriptionBindings
    null, // descriptionGroovyClasspath
    null, // descriptionPropertyKey
    null, // javascriptFile
    null, // javascript
    false, // saveJSONParameterToFile
    false, // quoteValue
    10, // visible item count
    "Select your options", // description
    "," //multiSelectDelimiter
)

normalChoiceOptions = ["option1","option2"]

properties([
        parameters([
                choice(choices: normalChoiceOptions.join("\n"), description: 'Single select option', name: 'SOME_OPTION'),                
                extendedChoiceParameterDefinition
        ])
])

I have seen a working example that uses the below syntax:

build job:'NameOfTheJob', parameters: [
      string(name: 'FirstOption', value: "test"),
      string(name: 'AnotherOption', value: "test12")
]

Basically, don't treat the choice parameters in a special manner, just treat them as regular string parameters.
