我正在通过 maven 在 eclipse 上运行一个项目，并且我已经在我的系统上设置了一个环境变量，以便我的项目能够正常工作。

这是一个示例代码：

public class StepDefFile {

    WebDriver driver = CaptureScreenshot.driver;
    public static String configFilePath =System.getenv("configFilePath");

    @Given(Login to application")
    public void Login_to_application() throws Throwable {
        driver = Helper.initializeDriver(); 
    }
}

但是当我运行mvn test时，我得到了 java nullPointerException，因为它在运行测试时无法找到该config.properties文件。

请检查下图以获取 Maven 错误日志

在此处输入图像描述

我已经尝试了以下链接的解决方案，但它对我不起作用：

从 maven 传递一个 java 参数

使用 Maven 的环境变量

我的pom.xml文件如下：

我想通过将我的配置文件作为环境变量传递来通过 maven 运行上述代码。

添加系统环境变量时，请务必确保重新启动机器，您计划在脚本中访问该变量。

以下是详细原因：

This behavior occurs because services that run under the Local System account inherit their environment from the Services.exe process. The Services.exe process receives the environment settings for the Local System account when Windows starts. Because the Services.exe process does not use Windows Messaging, when it receives messages that indicate that a value has changed after Windows starts, the Services.exe process does not update its environment settings. You cannot force a service that is running to acknowledge a dynamic change to the environment of the Local System account.（来源微软支持网站）
