How to get the exception that was thrown when a Cucumber test failed in Java?

Question

I can perform actions on test failure by using:

@After
public void afterTest(Scenario scenario) {
    if (scenario.isFailed()) {
        /*Do stuff*/
    }
}

This is the workaround for cucumber-java version 4.8.0 using reflection.

import cucumber.api.Result;
import io.cucumber.core.api.Scenario;
import io.cucumber.core.logging.Logger;
import io.cucumber.core.logging.LoggerFactory;
import io.cucumber.java.After;
import org.apache.commons.lang3.ClassUtils;
import org.apache.commons.lang3.reflect.FieldUtils;

import java.io.IOException;
import java.lang.reflect.Field;
import java.net.URL;
import java.util.ArrayList;

@After
public void afterScenario(Scenario scenario) throws IOException {
    if(!scenario.getStatus().isOk(true)){
        logError(scenario);
    }
}

private static void logError(Scenario scenario) {
    try {
        Class clasz = ClassUtils.getClass("cucumber.runtime.java.JavaHookDefinition$ScenarioAdaptor");
        Field fieldScenario = FieldUtils.getField(clasz, "scenario", true);
        fieldScenario.setAccessible(true);
        Object objectScenario =  fieldScenario.get(scenario);

        Field fieldStepResults = objectScenario.getClass().getDeclaredField("stepResults");
        fieldStepResults.setAccessible(true);

        ArrayList results = (ArrayList) fieldStepResults.get(objectScenario);
        for (Result result : results) {
            if (result.getError() != null) {
                LOGGER.error(String.format("Error Scenario: %s", scenario.getId()), result.getError());
            }
        }
    } catch (Exception e) {
        LOGGER.error("Error while logging error", e);
    }
}
