Answer 1

Solution: In order to set ,get and access user input as a variable on jenkins pipeline, you should use ChoiceParameterDefinition , attaching a quick working snippet:

    script {
            // Define Variable
             def USER_INPUT = input(
                    message: 'User input required - Some Yes or No question?',
                    parameters: [
                            [$class: 'ChoiceParameterDefinition',
                             choices: ['no','yes'].join('\n'),
                             name: 'input',
                             description: 'Menu - select box option']
                    ])

            echo "The answer is: ${USER_INPUT}"

            if( "${USER_INPUT}" == "yes"){
                //do something
            } else {
                //do something else
            }
        }
