Cucumber selenium testng getting error in testrunner

Question

package Runner;

import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

import io.cucumber.testng.CucumberOptions;
import io.cucumber.testng.FeatureWrapper;
import io.cucumber.testng.PickleWrapper;
import io.cucumber.testng.TestNGCucumberRunner;

@CucumberOptions(
        features="src/test/resources/features",
        glue="steps"
      // plugin={"pretty", "io.qameta.allure.cucumber7jvm.AllureCucumber7Jvm"}
      //  tags="@Amazon"
)
public class TestRunner   {
    
    private TestNGCucumberRunner testNGCucumberRunner;

    @BeforeClass(alwaysRun = true)
    public void setUpClass() {
        testNGCucumberRunner = new TestNGCucumberRunner(this.getClass());
    }

    @Test(groups = "cucumber", description = "Runs Cucumber Scenarios", dataProvider = "scenarios")
    public void scenario(PickleWrapper pickle, FeatureWrapper cucumberFeature) {
        testNGCucumberRunner.runScenario(pickle.getPickle());
    }

    @DataProvider(name="myFeature")
    public Object[][] getFeatures()
    {
        
        if(testNGCucumberRunner==null) {
            
            testNGCucumberRunner = new TestNGCucumberRunner(this.getClass());
        }
        return testNGCucumberRunner.provideScenarios();
    }

    @AfterClass(alwaysRun = true)
    public void tearDownClass() {
        testNGCucumberRunner.finish();
    }
}

I've tried this:

import org.testng.annotations.Test;
import cucumber.api.CucumberOptions;
import cucumber.api.testng.AbstractTestNGCucumberTests;

@CucumberOptions(features={"src//main//java//features"}
        ,glue={"stepdefinations","utility"}
        ,plugin = {"pretty", "html:target/cucumber"}
        , tags ={"@appium"}
)
@Test
public class RunTest extends AbstractTestNGCucumberTests{

}

Here's the error I'm getting:
