Question

所以我在OpenHAB内运行Raspberry Pi并将.jar文件保存在我的OS X中，并在OS X终端中运行它，我收到以下错误。能告诉我如何解决这个问题吗？

java -jar amazon-echo-bridge-0.2.1.jar –upnp.config.address=192.168.1.105

我已从here下载了jar文件，我正在关注this tutorial。

jar在Raspbian中运行，但我希望从OS X运行它，因为I cannot install Chromium on Raspbian.

然而，即使在Raspbian中运行，我也会收到此错误：

莫纳，

您正在尝试使用Java 7运行Jar文件，而它设计为在Java 8上运行。安装Java 8并使用它来运行Jar来修复错误。

在Raspberry Pi上使用Amazon Echo控制OpenHAB
