InvocationTargetExceptionMessage 是：不可能创建新的 session 因为“createSession”错误

Question

I am trying to set up a simple selenium Framework to run off Appium. The test should simply open Chrome on an android device. I have created my Baseclass which us unfortunately returning an error

My original thinking was that this issue was related to the URL which is http://0.0.0.0:4723/wd/hub , I changed it but the error was still displayed. I have also changed my Java version client but every time I do this another error appears!!

My Appium version is the following..

[Appium] Welcome to Appium v1.14.2 [Appium] Appium REST http interface listener started on 0.0.0.0:4723

this is my BaseClass

package tests;

import java.net.URL;

import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
import io.appium.java_client.remote.MobileCapabilityType;

public class BaseClass {


    AppiumDriver<MobileElement> driver;

    @BeforeTest
    public void setup() {

        try {

        DesiredCapabilities caps = new DesiredCapabilities();

        caps.setCapability(MobileCapabilityType.PLATFORM_NAME, "ANDROID");
        caps.setCapability(MobileCapabilityType.VERSION, "6.0.1");
        caps.setCapability(MobileCapabilityType.DEVICE_NAME, "Nexus 7");
        caps.setCapability(MobileCapabilityType.UDID, "0911b4aa");
        caps.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, 60);
   //       caps.setCapability(MobileCapabilityType.APP, "");
        caps.setCapability(MobileCapabilityType.BROWSER_NAME, "Chrome");
        URL url = new URL("http://0.0.0.0:4723/wd/hub");

        driver = new AppiumDriver<MobileElement>(url,caps);


        }catch(Exception  exp) {
            System.out.append("cause is  : "+exp.getCause());
            System.out.append("Message is : "+exp.getMessage());
            exp.printStackTrace();
        }
    }
    @Test
    public void sampleTest() {
        System.out.print("I am running a test");
    }

    @AfterTest
    public void teardown() {
        driver.close();
        driver.quit();

    }

}

This is my POM File...

I can see in the error response that AAPT is mentioned and that is to do with the Android SDK. here is my.profile file where my SDK info is stored...

Adding path of platform tools folder in path environments variable export PATH="/usr/local/Caskroom/android-sdk/4333796/platform-tools:$PATH"

Setting PATH for ANDROID_HOME export ANDROID_HOME="/usr/local/share/android-sdk"

Answer 1

The error seems to be that it does not find the class LoggingHandler . That class is usually in the selenium-api dependency. You can try to use 2.53.1 version instead of 3.4.0. That version has the missing class.

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-api</artifactId>
    <version>2.53.1</version>
</dependency>
