Method threw 'java.lang.NoClassDefFoundError' exception./ org/openqa/selenium/remote/internal/JsonToWebElementConverter: Appium Android

[Dmitry_A]

Hello everyone
I use Java/Junit5/maven in automation. and IntelliJ Idea

I have these dependencies:

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-remote-driver</artifactId>
        <version>4.1.1</version>
    </dependency>

      <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>4.1.1</version>
    </dependency>

    <dependency>
        <groupId>io.appium</groupId>
        <artifactId>java-client</artifactId>
        <version>7.6.0</version>
    </dependency>

I have this code for running test:

return new AndroidDriver(new URL("http://localhost:4723/wd/hub"), caps);

where caps:
Capabilities {NameDevice: Nexus_6, androidScreenshotPath: screenshots, avd: Nexus_6, browserName: chrome, chromedriverExecutable: io.github.bonigarcia.wdm.ma…, defaultCapabilities: [“chromeOptions”,{“w3c”:fal…, deviceName: Nexus_6 forceMjsonwp: true, isMobile: True, nativeWebScreenshot: true, platformName: Android, traceCategories: browser,devtools.timeline,d…, version: MOBILE}
PS i tried to send empty caps - the same error

and when i call this: I receive this error:
org/openqa/selenium/remote/internal/JsonToWebElementConverter - in detailsMessage
and in debbug: Method threw ‘java.lang.NoClassDefFoundError’ exception.

and really don’t understand what is the issue.
As I understand it is before sending request to appium.

did u have the same issue?

the same i use 8.0.0-beta appium:
i used these commands
sudo npm install -g appium@beta --unsafe-perm=true --allow-root
appium

Looks like a dependency issue:

Are you getting the same error or something different? Here is a tutorial on adding Appium dependencies to Maven:
