在 Device Farm 中访问 TestNG 测试的测试资源时出现问题

如何解决在 Device Farm 中访问 TestNG 测试的测试资源时出现问题

我正在尝试从 Amazon Device Farm 运行 Appium TestNG 测试。我已将测试转换为 Jar 文件，以便我可以运行测试。问题是当我尝试从 json 文件中获取测试数据时保存在 src/main/resources 下，它抛出一个 NULL 指针异常。它在本地按预期工作

src\main\resources 包下有一个名为 testdata 的包，用于存储 testdata JSON 文件

  InputStream input=Thread.currentThread().getContextClassLoader().getResourceAsstream("testdata//"+"inputdata.json");
