I found a similar error as mine on stackoverflow and added selenium webdriver jar files to the project using the below method :
right click on project--> goto build
Please follow the below steps:
I had the same problem but then i came to know that i was missing a jar to add, this jar is not inside the lib folder you can find it immediately outside the lib folder: client-combined-3.0.1-nodeps.jar
You just need to import two links:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
or you can follow that tutorial:

It works for me.
WebDriver3.0 will support the latest firefox also. but you have to set the properties for that
download "geckodriver.exe" file and you can try this.
System.setProperty("webdriver.firefox.marionette",
"E:\\SeleniumAutomation\\geckodriver-v0.9.0-win64\\geckodriver.exe");
driver = new FirefoxDriver();
driver.get("http://stackoverflow.com/");
This error happens when you use Eclipse as IDE and try to run code that doesn't even compile. Check your Problems view in Eclipse, and fix the compilation errors before executing the application.
I had the problem of WebDriver cannot be resolved to a type FirefoxDriver cannot be resolved to a type.I was using Selenium -java 3.0.1 jars.Also the jars client-combined-3.0.1-nodeps are required to to added .hence problem solved.
