Java Selenium:错误：无法访问可变功能

尝试将代码更新为Selenium 3.x，但在尝试运行测试时，我一直遇到一个错误：

error: cannot access MutableCapabilities

这段代码在运行测试时也可以使用，我不确定它在哪里或者为什么会出现这样一个奇怪的错误。我似乎找不到任何人以前写过的东西，所以我希望stackoverflow社区能在这方面帮助我

以下是生成此错误的代码：

package com.iacapps.ste.ta.helpers;

import com.google.common.base.Strings;
import com.paypal.selion.platform.grid.browsercapabilities.DefaultCapabilitiesBuilder;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.Collections;

public class CustomCapabilities extends DefaultCapabilitiesBuilder
{
  private static final Logger logger = LoggerFactory.getLogger(DefaultCapabilitiesBuilder.class);

  private static final String SAUCE_TUNNEL_PROPERTY = "sauceTunnel";
  private static final String SAUCE_ENABLED_PROPERTY = "enableSauceConnect";
  private static final String TUNNEL_CAPABILITY = "tunnelIdentifier";
  private static final String ACCEPT_ALL_SSL_CAPABILITY = "acceptSslCerts";
  private static final String CHROME_SWITCHES = "chrome.switches";
  private static final String CHROME_IGNORE_SSL = "--ignore-certificate-errors";
  private static final String FIREFOX_ACCEPT_BAD_CERTS_CAPABILITY = "acceptInsecureCerts";

  @Override
  public DesiredCapabilities getCapabilities(DesiredCapabilities capabilities)
  {
    String sauceEnabledValue = System.getProperty(SAUCE_ENABLED_PROPERTY);
    String tunnelIdValue = System.getProperty(SAUCE_TUNNEL_PROPERTY);
    //This will just prevent the warning being printed when sauceconnect isn't enabled.
    if (!Strings.isNullOrEmpty(sauceEnabledValue) && Boolean.valueOf(sauceEnabledValue))
    {
      if (Strings.isNullOrEmpty(tunnelIdValue))
      {
        logger.warn("{} not set", SAUCE_TUNNEL_PROPERTY);
      }
      else
      {
        capabilities.setCapability(TUNNEL_CAPABILITY, tunnelIdValue);
      }
    }
    //There's a reason for this charlie foxtrot.  I don't always get to know what browser driver I'm
    //talking to.
    //Per selenium docs: "Whether the session should accept all SSL certs by default."
    //The DOWNSIDE: this seems to work with newer browser drivers, but it may not work with old ones.
    capabilities.setCapability(ACCEPT_ALL_SSL_CAPABILITY, true);
    //This *supposedly* works with some versions of IE.
    capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
    //This *supposedly* works with some chrome versions.

    capabilities.setCapability(CHROME_SWITCHES, Collections.singletonList(CHROME_IGNORE_SSL));
    //Oh my god please work you STUPID FIREFOX
    //http://stackoverflow.com/a/40788935
    //https://bugzilla.mozilla.org/show_bug.cgi?id=1103196
    //Should work with firefox > v51
    capabilities.setCapability(FIREFOX_ACCEPT_BAD_CERTS_CAPABILITY,true);
    //When in doubt SET EVERYTHING!
    FirefoxProfile profile = new FirefoxProfile();
    profile.setAcceptUntrustedCertificates(true);
    profile.setAssumeUntrustedCertificateIssuer(false);
    capabilities.setCapability(FirefoxDriver.PROFILE,profile);
    capabilities.setCapability(FirefoxDriver.MARIONETTE,false);
    return capabilities;
  }
}

好吧，事实证明，我的问题是因为maven中的一些依赖关系让我完全被轴所包围。我在这里发帖，希望如果有人遇到这个问题，他们可以看看这里，看看到底发生了什么

因此，对我来说，以下工件不在selenium的正确匹配版本上：

• selenium支持

• seleniumjava

• selenium api

---

一旦我将它们更正为我正在运行的selenium的同一版本（3.5.3），我就能够成功地打开firefox，而没有之前遇到的异常情况。

我一直遇到这个问题， 我的解决方案是添加/更新pom.xml

这个类的具体用途是什么？你如何使用它？您真的需要扩展

DefaultCapabilitiesBuilder

来创建一组自定义功能吗？我需要将浏览器移动代理信息附加到测试中。如果我使用saucelabs进行测试，我需要输入SauceConnect代理信息。这很好。但我看不出有任何理由在这里使用

DefaultCapabilitiesBuilder

。您可以使用公共java方法执行相同的操作，该方法返回

DesiredCapabilities

。这就是为什么我要求您显示一段代码，其中使用了这个类。@SergeyKorol-这个生成器是通过JVM参数或服务加载器注入的。请参阅（或）>>这很有帮助。在一个依赖项上更改了版本号之后，我收到了类似的消息。
