在火狐和ie 下都报这个错==============
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/base/Function

代码===============
public static void main(String[] args) {
  System.setProperty("webdriver.firefox.bin", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
  //WebDriver wb = new InternetExplorerDriver();
  WebDriver wb = new FirefoxDriver();
  //System.out.println("test");
  wb.get("http://www.baidu.com");
  wb.close();
}
========selenium2 + 64 win8.1 + jdk1.7 ie 11 /火狐 38.0.5

大神帮忙给看下，什么原因
