Getting an error when I try to run a simple Java - Selenium project
问题
我尝试运行这个简单的项目。我已经将所有 Selenium JAR 文件应用到了构建路径中，`chromedriver` 文件位于我的桌面上：
```java
package XYZ;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class SeleniumScript {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.setProperty("webdriver.chrome.driver", "/Users/MYNAME/Desktop/chromedriver");
WebDriver driver = new ChromeDriver();
driver.get("https://google.com/");
System.out.print(driver.getTitle());
driver.quit();
}
}
但我得到了以下错误：

我期望控制台输出页面标题。

I try to run this simple project. I have all Selenium JAR files applied in the build path and the `chromedriver` file is located on my desktop:
package XYZ;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class SeleniumScript {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.setProperty("websdriver.chrome.driver", "/Users/MYNAME/Desktop/chromedriver");
WebDriver driver = new ChromeDriver();
driver.get("https://google.com/");
System.out.print(driver.getTitle());
driver.quit();

}
And I get the following error:

com.google.common.io.ByteStreams 类是 Guava 库的一部分。您需要将此库添加到您的类路径中。
如果您使用 Maven，您可以添加以下依赖项：
<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>32.1.1-jre</version>
</dependency>
到您的 POM 中。
如果您不使用 Maven，请下载 JAR 文件并手动将其添加到类路径中。
顺便说一句：请注意 Java 命名约定。包名应为小写。
英文:
The class com.google.common.io.ByteStreams is part of the Guava libraries. You have to add this library to your class path.
If you use Maven, you can add the dependency:
<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>32.1.1-jre</version>
</dependency>
to your POM.
If you not use Maven, download the JAR file and add it to the class path manually.
BTW: Take care of Java naming conventions. Package names should be lowercase.
