如何在机器人类中按 ENTER 键？

Question

我创建了一种方法来从 Firefox 工具栏中单击特定插件，并且在 Windows 操作系统上一切正常。但是当我尝试从使用 Linux 机器的 Jenkins 服务器执行相同的操作时，它无法执行 robot.keyPress(KeyEvent.VK_Enter)。

    Robot robot = new Robot();
    robot.keyPress(KeyEvent.VK_CONTROL);
    robot.keyPress(KeyEvent.VK_L);
    robot.keyRelease(KeyEvent.VK_L);
    robot.keyRelease(KeyEvent.VK_CONTROL);
    Thread.sleep(2000);

    //move to addons
    Robot robot1 = new Robot();
    robot1.keyPress(KeyEvent.VK_TAB);
    robot1.keyRelease(KeyEvent.VK_TAB);
    Thread.sleep(1000);
    robot1.keyPress(KeyEvent.VK_TAB);
    robot1.keyRelease(KeyEvent.VK_TAB);
    Thread.sleep(1000);

    //move to simple-modify-header addon
    Robot robot3 = new Robot();
    robot3.keyPress(KeyEvent.VK_RIGHT);
    robot3.keyRelease(KeyEvent.VK_RIGHT);
    Thread.sleep(2000);
    robot3.keyPress(KeyEvent.VK_RIGHT);
    robot3.keyRelease(KeyEvent.VK_RIGHT);
    Thread.sleep(2000);
    robot3.keyPress(KeyEvent.VK_RIGHT);
    robot3.keyRelease(KeyEvent.VK_RIGHT);
    Thread.sleep(2000);
    robot3.keyPress(KeyEvent.VK_RIGHT);
    robot3.keyRelease(KeyEvent.VK_RIGHT);
    Thread.sleep(2000);


    //click simple-modify-header addon
    Robot robot2 = new Robot();
    robot2.keyPress(KeyEvent.VK_ENTER);
    robot2.keyRelease(KeyEvent.VK_ENTER);
    Thread.sleep(1000);

我尝试使用不同的机器人实例，但它仍然卡在按 ENTER 键。

这对我来说很好用：

public static void robotDoEnter()
    {
        try {
            Robot robot = new Robot();
            robot.keyPress(KeyEvent.VK_ENTER);
            robot.delay(300);
            robot.keyRelease(KeyEvent.VK_ENTER);
            robot.delay(300);
        } catch (AWTException e) {
            e.printStackTrace();
        }
    }
