cucumber.runtime.CucumberException:未能实例化stepDefinitions类

我正在尝试运行用java编写的cucumber测试

一切似乎都正常运行，除了在实现功能文件之后，我开始出现以下错误：cucumber.runtime.CucumberException:未能实例化stepDefinitions类

                 Assert.assertEquals(loginSuccess.getText(),"Home");
            }
        }

项目结构如下：

StepDefinitons类如下所示。首先我运行feature文件，然后我得到了需要在stepDefinitons类中实现的方法

实例化失败，因为无法使用默认构造函数创建步骤为的新对象

public class Steps {

    private static WebDriver driver;
    WebDriverWait wait=new WebDriverWait(driver, 20);

    ...

因为

driver

尚未在

newwebdriverwait（driver，20）

初始化

要初始化

驱动程序

，可以使用

@Before

（在场景之前执行）或

@BeforeStep

（在步骤之前执行）注释方法

您能提供
Steps.java
类的内容吗？您是否尝试过在
stepDefinitions
包中没有任何类的情况下运行它？你应该得到要实现的方法的列表。是的，我得到了，它要求我实现方法，然后它停止工作，然后你应该提供
步骤。java
。我已经添加了我的Steps.java类你能提供
