Selenium 尝试使用ExtentReports生成测试报告时获取NullPointerException

我的代码如下所示

ExtentReports extentReports = ExtentReports.get(OpportunityTest.class);
extentReports.init("C:\\DSMB_QA\\DigtalSMB\\src\\test\\lib\\emailtest.html",true);
extentReports.startTest("First test");

日志是

请检查扩展报告的更新代码文档。我建议使用版本2+。这是对版本1的巨大改进，根据文档，9月31日后将不支持此版本。
