Java cucumber.runtime.CucumberException:未能实例化类stepDefinitions.RegistrationStepDefinition

我把cucumber和testNG作为一个maven项目来运行。我的项目包含两个功能文件“login.feature”和“registration.feature”。“login.feature”已成功执行。但当涉及到“registration.feature”文件时，它会显示生成失败以及此异常。请调查一下，给我解决办法

和test runner.java文件：

@CucumberOptions(
        features = "C:\\Users\\HP\\workspace\\FbLoginTestUsingCucumberTestNG\\src\\main\\java\\features",
        glue = {"stepDefinitions"},
        tags="@LoginFeature, @RegistrationFeature",
        plugin={"html:target/cucumber-html-report"}

        )

public class TestRunner {
    private TestNGCucumberRunner testNGCucumberRunner;

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

    @Test(groups = "cucumber", description = "Runs Cucumber Feature", dataProvider = "features")
    public void feature(CucumberFeatureWrapper cucumberFeature) {
        testNGCucumberRunner.runCucumber(cucumberFeature.getCucumberFeature());
    }

    @DataProvider
    public Object[][] features() {
        return testNGCucumberRunner.provideFeatures();
    }

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