Using Snippet Generator for creating an input statement with choice parameter you get next sentence:

input message: 'Environment to Deploy', parameters: [[$class: 'ChoiceParameterDefinition', choices: ['local','pre'], description: '', name: 'environment']]

But then when you execute the script you get next exception:

Re: Snippet generator creates wrong input statement with ChoiceParameter

Use this example, for fix the error, it work perfectly:

properties ([[$class: 'hudson.model.ParametersDefinitionProperty', parameterDefinitions: [[$class: 'hudson.model.ChoiceParameterDefinition', choices: 'Value1\nValue2' , description: '', name: 'unChoiceParameter']]]])
