Hi,
I’m a new Appium user and I’m following with an Appium tutorial and when I try to run my script I’m getting the following error :

"Exception in thread “main” java.lang.NoClassDefFoundError: org/openqa/selenium/remote/AcceptedW3CCapabilityKeys

I’ve tried to remove the selenium jars and relaunch eclipse and the emulator with no benifits.

here’s my script:
"import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.remote.DesiredCapabilities;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
import io.appium.java_client.remote.MobileCapabilityType;

public class base {

public static void main(String[] args) throws MalformedURLException {

	File f = new File("src");
	File fs = new File(f,"ApiDemos-debug.apk");
	URL ServerURL = new URL("http://127.0.0.1:4723/wd/hub");
	
	DesiredCapabilities cap = new DesiredCapabilities();
	cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Demo");
	cap.setCapability(MobileCapabilityType.APP, fs.getAbsolutePath());
	AndroidDriver<AndroidElement> driver = new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"),cap);
	
}

}"
