Java 无法将json测试数据文件读入我的stepDef

无法将json测试数据文件读入我的stepDef。当我尝试在maven中执行此操作时，我得到下面的错误消息

我的情景 场景大纲：JSON关键字示例 假设我在github登录页面上 #我输入“”和“” 我输入用户名和密码

Examples: {'datafile':'./src/main/resources/data/testData.json'}

My testData.json

[
  { "username" : "jsonuser1" , "password":"jsonpass1" , "isvalid":"false" }
]

分步定义

@And("^I enter usernames and passwords$")
public void iEnterUsernamesAndPasswords(Map<Object, Object> data) {
    System.out.println("*************************"+ data.get("username") + data.get("password"));
    
}

@和（“^I输入用户名和密码$”）
公用无效IEnterUserNames和密码（地图数据）{
System.out.println（“*************************”+data.get（“用户名”）+data.get（“密码”））；
}

错误消息：

测试运行：1，失败：1，错误：0，跳过：0，经过的时间：4.093秒对于任何需要参数的步骤，您需要在定义步骤时指定参数占位符，并需要提供调用时间的值。
在您的情况下，请尝试更新步骤定义，如下所示：

@And("^I enter usernames and passwords \"([^\"]*)\"$")
public void iEnterUsernamesAndPasswords(Map<Object, Object> data) {
System.out.println("*************************"+ data.get("username") + data.get("password"));
}

  Scenario Outline: JSON Keyword Example
    Given I am on github login page
    And I enter usernames and passwords "${args[0]}"
