Question

我正在通过Maven在Eclipse上运行一个项目，并且在我的系统上设置了一个环境变量以使我的项目能够正常工作。

这是示例代码：

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，我得到的是Java nullPointerException，因为它在运行测试时找不到config.properties文件。

请检查下面的图像以获取Maven错误日志

我已经从下面的链接尝试了解决方案，但是对我来说不起作用：

我想通过将配置文件作为环境变量传递来通过maven运行以上代码。

Answer 1

在添加计划要在脚本中访问的系统环境变量时，请务必确保重新启动计算机。

这是详细原因：

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Microsoft支持网站）
