在 Jenkins 上运行时，我在使用 Seleinum 代码上传文件时遇到问题。我的 Selenium 代码在本地运行良好，能够上传并完成测试。但是，在 Jenkins 上运行时，WebElement.SendKeys(..) 抛出了异常，提示“org.openqa.selenium.InvalidArgumentException：参数无效：未找到文件”。我在代码中启动了一个新的 File(..)，并通过 file.exists() 测试了文件是否存在，结果确实存在。

driver.get(Configuration.getEnvArg("test_url")+"mylist/doc-upload");
String userDir = System.getProperty("user.dir");
String appendPath = File.separator + "src" + File.separator + "main" + File.separator + "resources" + File.separator + "files" + File.separator + fileName + "." + fileExt;
File file = new File(path);
LOGGER.info(path + " is exist: " + file.exists());
LOGGER.info("absolute path: " + file.getAbsolutePath());
WebElement el = driver.findElement(By.id(submitId));
el.sendKeys(file.getAbsolutePath());  // exception is thrown at this point.
pause(20);

(I replaced part of the path with xxx for posting purpose.)

任何建议都值得赞赏。
