我正在使用appium studio，我从那里获取了代码，并在Eclipse中从中复制了代码。我添加了所有maven依赖项，即使它抛出了 FAILED配置错误。是否有人帮助我？有了这个？ 注意：我在这里使用Real device ios，我的平台是mac。 Java版本“ 11.0.2” 

package iostestdemo;

import io.appium.java_client.remote.IOSMobileCapabilityType;
import io.appium.java_client.ios.IOSDriver;
import io.appium.java_client.ios.IOSElement;
import io.appium.java_client.remote.MobileCapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.By;
import org.testng.annotations.*;
import java.net.URL;
import java.net.MalformedURLException;
import java.util.logging.Level;

public class secondTest {
    private String reportDirectory = "reports";
    private String reportFormat = "xml";
    private String testName = "Untitled";
    protected IOSDriver<IOSElement> driver = null;

    DesiredCapabilities dc = new DesiredCapabilities();

    @BeforeMethod
    public void setUp() throws MalformedURLException {
        dc.setCapability("reportDirectory", reportDirectory);
        dc.setCapability("reportFormat", reportFormat);
        dc.setCapability("testName", testName);
        dc.setCapability(MobileCapabilityType.UDID, "afb65172e9b47b01482d912dede58515819748a3");
        dc.setCapability(IOSMobileCapabilityType.BUNDLE_ID, "com.novo.ios.dev");
        driver = new IOSDriver<IOSElement>(new URL("http://localhost:4723/wd/hub"), dc);
        driver.setLogLevel(Level.INFO);
    }

    @Test
    public void testUntitled() {

        driver.findElement(By.xpath("//*[@placeholder='Email']")).click();
        driver.findElement(By.xpath(
                "(//*[@text='Novo - Dev']/*/*[@class='UIAView' and ./*[@class='UIAView' and ./*[@class='UIAView']] and ./parent::*[@class='UIAWindow']])[2]"))
                .click();
        driver.findElement(By.xpath("//*[@placeholder='Email']")).click();
        driver.findElement(By.xpath("//*[@placeholder='Email']")).sendKeys("ababddvdvd");
        driver.findElement(By.xpath("//*[@placeholder='Password']")).sendKeys("vvv");
        driver.findElement(By.xpath("//*[@text='LOG IN']")).click();
        driver.findElement(By.xpath("//*[@text='OK']")).click();
    }
}

您患有JAR Hell

查看dependencies for Appium Java Client 7.1.0已经取决于Selenium 4.0.0-alpha-1

由于在pom.xml文件和Appium Java Client的transitive dependencies中声明的依赖关系之间的冲突，您会收到错误消息

您基本上只需要Appium Java客户端即可运行基于Appium的测试，不需要添加Selenium库，相关版本将自动解决：

<dependencies>
    <dependency>
        <groupId>io.appium</groupId>
        <artifactId>java-client</artifactId>
        <version>7.1.0</version>
    </dependency>
    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.14.3</version>
    </dependency>
</dependencies>

我也遇到了这个问题，我很难解决。我认为appium（7.1.0）和硒（3.141.59）依赖关系的版本互不支持。我像下面这样更改了版本，它为我解决了：

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>2.53.1</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>io.appium</groupId>
    <artifactId>java-client</artifactId>
    <version>4.1.2</version>
</dependency>
