Step expected in Jenkins Groovy script

Question

I am having below groovy script for my Jenkins pipeline. But when running its giving error as step expected where my script already having step. Can anyone suggest what's wrong here..

Script file

pipeline {
agent any
stages {
    stage('Workspace Preparation') {
        steps {
            sh """
                rm -rf ${workspace}/*
            """
        }
    }
   stage('Get Deployment files') {
       steps {
            dir("${workspace}/deployfiles") {
                if("${params.componentType}"=="A") {
                    echo "A component deployment"
                    checkout(## necessary step)
                }
                else if ("${params.componentType}"=="B") {
                    echo "B component deployment"
                    checkout(## necessary step)
                }
                else  {
                    echo "Invalid"
                }


              }
       }
    }
}

}

Getting error as

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 19: Expected a step @ line 14, column 6.
                    if("${params.componentType}"=="A") {
        ^

You are missing a script-block. (Source)

Such a block gives you acces to execute groovy code (for, if-else etc. etc.)

stage('Check') {
        steps {        
            script { // Allows to execute groovy code
               dir (...) {
                 if (...)
               }    
            }         
        }
