Question

我无法在我的Selenium项目中设置BrowserMob代理。就像described in BrowserMob Proxy github page我在我的代码中导入它一样：

public class DriverBase {
    public WebDriver driver;
public BrowserMobProxy proxy;

    @Before
    public void setUp() {
    proxy = new BrowserMobProxyServer();
        proxy.start(0);

     Proxy sproxy = ClientUtil.createSeleniumProxy(proxy);

        DesiredCapabilities caps=new DesiredCapabilities();
        caps.setCapability(CapabilityType.PROXY, sproxy);
 driver = new ChromeDriver(caps);

我从browsermob-core中排除了slf4j传递依赖，并添加了slf4j-jdk14，以便服务器可以启动（原来它不能）。

 <dependency>
        <groupId>net.lightbody.bmp</groupId>
        <artifactId>browsermob-core</artifactId>
        <version>2.1.5</version>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium</artifactId>
                 </exclusion>
                    <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>jcl-over-slf4j</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.google.guava</groupId>
                <artifactId>guava</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-jdk14</artifactId>
        <version>1.8.0-beta0</version>
    </dependency>

我还手动添加了com.google.guava 19.0，因为服务器没有以最新的番石榴版本开头。

    <dependency>
        <groupId>com.google.guava</groupId>
        <artifactId>guava</artifactId>
        <version>19.0</version>
    </dependency>

在我的测试类中，我只启动浏览器：

public class TrafficTest extends DriverBase{

 @Test
 public void testTraffic()    {    
    driver.navigate().to("http://liveexpert.ru");
}

浏览器启动，但不会打开网站或访问互联网。原始的browsermob-core maven设置甚至无法启动服务器或浏览器。当前设置会引发错误：

    java.lang.NoSuchMethodError: com.google.common.net.HostAndPort.getHost()Ljava/lang/String;

这是完整的日志

是否有解决方法来设置驱动程序以访问互联网？

Answer 1

现在解决方案是使用guava 22.0。

番石榴版本18,19引起了问题：

java.lang.NoSuchMethodError: com.google.common.net.HostAndPort.getHost()

为什么explained here。

最新版本的guava 23.x解决了这个问题，但反过来又引发了另一个问题：

java.lang.IllegalAccessError: tried to access method com.google.common.util.concurrent.SimpleTimeLimiter.<init>(Ljava/util/concurrent/ExecutorService;)V from class org.openqa.selenium.net.UrlChecker
