chrome Webdriver can't be resolved to a type error eclipse and java

Im trying to do some automation projects with chrome, java and selenium and having problems importing the chrome driver.

package main;

import org.openqa.selenium.*;

public class SitePoster {

    public static void main(String[] args) {
         //System.setProperty("webdriver.chrome.driver", "./pathtodriver");
        WebDriver driver = new ChromeDriver();
        //Getting error saying "ChromeDriver can't be resolved to a type"
    } 

}
