Cucumber failed to instantiate class, steps undefined

Question

I keep getting these errors every time I try to run my test using cucumber with selenium:

cucumber.runtime.CucumberException: Failed to instantiate class br.gov.pb.receita.atfbdd.steps.arrecadacao.ConsultarLancamentoARR001 - this class doesn't have an empty or a page enabled constructor"

cucumber.runtime.junit.UndefinedThrowable: The step "O sistema exibe uma lista contendo os lan�amentos obtidos" is undefined

I've tried to run my step class whith and whitout ScenarioSteps and, as you can see, it does have an empty constructor.

But, even extending ScenarioSteps in my step class, I'm keep getting these errors "cucumber.runtime.junit.UndefinedThrowable: The step is undefined", as shown above.

Here's my step class:

@CucumberOptions(features = "classpath:features/arrecadacao/")
public class ConsultarLancamentoARR001 extends ScenarioSteps {

    Selenium selenium;

    public ConsultarLancamentoARR001() {

    }

    ConsultarLancamentoPage consultarLancamento = new ConsultarLancamentoPage(selenium.getDriver());
    LoginPage loginPage = new LoginPage(selenium.getDriver());

    @Step
    @Given("^Eu desejo acessar o sistema ATF$")
    public void euDesejoAcessarAtf() throws Exception {
        selenium.getDriver().navigate().to(ConfiguracaoATF.URL_ADDRESS_DES);
    }

    @Step
    @When("^Eu informo as credenciais de login$")
    public void euInformoCredenciaisLogin() throws Exception {
        loginPage.logarSistemaViaCredenciaisUsuario(DadosConfigARR.USUARIO_ADMIN_DES, DadosConfigARR.SENHA_ADMIN_DES);
    }

    @Step
    @Then("^Eu devo logar no sistema com sucesso$")
    public void euLogoComSucesso() throws Exception {
        assertEquals("Lotação:", selenium.getDriver().findElement(By.xpath("/html/body/table/tbody/tr[2]/td/table/tbody/tr[3]/td[1]")));
    }

    @Step
    @Given("^Eu solicito a funcionalidade Consultar Lançamento$")
    public void euSolicitoConsultarLancamento() throws Exception {
        consultarLancamento.acessarFuncionalidadeARR_001();
    }

    @Step
    @When("^Eu informar os dados para consulta$")
    public void euInformoDadosConsulta() throws Throwable {
        consultarLancamento.informarNumeroLancamento(DadosConfigARR.NOSSO_NUMERO_REG1);
        consultarLancamento.descerBarraDeRolagemCompletamente();
        consultarLancamento.clicarBotaoConsultarLancamento();
        Thread.sleep(2000);

    }

    @Step
    @Then("^O sistema valida as informações e executa a consulta$")
    public void oSistemaValidaInformacoes() throws Throwable {
        consultarLancamento.naoSelecionarNenhumItem();
        Thread.sleep(2000);

        assertEquals("Selecione um item", consultarLancamento.capturarPopupAlerta());

        consultarLancamento.detalharLancamento();
        Thread.sleep(5000);
    }

    @Step
    @And("^O sistema exibe uma lista contendo os lançamentos obtidos$")
    public void oSistemaExibeLancamentos() throws Throwable {
        consultarLancamento.detalharLancamento();
        Thread.sleep(5000);
    }

}

Here's my runner:

@RunWith(CucumberWithSerenity.class)
@CucumberOptions(
        features = "src/test/resources/features/arrecadacao/",
        glue = "classpath:br.gov.pb.receita.atfbdd.steps.arrecadacao")

public class CucumberRunnerARR {

    protected static WebDriver driver;

    @BeforeClass
    public static void beforeClass() throws Exception {
        driver = Selenium.getInstance().getDriver();
        driver.manage().window().maximize();
//      LoginPage loginPage = new LoginPage(driver);
//      loginPage.logarSistemaViaCredenciaisUsuario(DadosConfigARR.USUARIO_ADMIN_DES, DadosConfigARR.SENHA_ADMIN_DES);
    }

    @AfterClass
    public static void afterClass() throws Exception {
        driver.quit();
    }
}

Here's my .feature:

Feature: Consultar lançamento

  O usuário consulta um lançamento no sistema ATF

  Background: O usuário está logado
    Given Eu desejo acessar o sistema ATF
    When Eu informo as credenciais de login
    Then Eu devo logar no sistema com sucesso

  @CT015
  Scenario: Fluxo básico de eventos
    Given Eu solicito a funcionalidade Consultar Lançamento
    When Eu informar os dados para consulta
    Then O sistema valida as informações e executa a consulta
    And O sistema exibe uma lista contendo os lançamentos obtidos

And, if it helps, here's how the project is organized:

What am I doing wrong?

Check for the `NUllPointerException` at `(ConsultarLancamentoARR001.java:34)`. — SubOptimal, Sep 18 '18 at 13:39

Pretty sure i had this issue, below are my package.json files, ensure you are using the same versions of everything, i believe something is too high of a version or too low of a version, i cannot remember which way round it was.

{
  "name": "hellocucumber",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "cls && cucumber-js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "chai": "^4.1.2",
    "chromedriver": "^2.41.0",
    "cucumber": "^4.2.1",
    "node-key-sender": "^1.0.10",
    "selenium-cucumber-js": "^1.5.13"
  },
  "dependencies": {
    "gherkin": "^5.1.0",
    "selenium-webdriver": "^4.0.0-alpha.1"
  }
}

I know you're not using a package.json file, however if you use my version numbers to go off, you should be able to figure out if the versions are the same as the ones you have imported into your project.
