java - 在 Raspberry Pi 上使用 Amazon Echo 控制 OpenHAB

Question

所以我在 Raspberry Pi 中运行 OpenHAB，并将 .jar 文件保存在我的 OS X 中，然后在 OS X 中运行它终端，我收到以下错误。您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

我已经从here下载了jar文件我正在关注this tutorial .

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

但是，即使在 Raspbian 中运行，我也会收到此错误:

莫娜，

您尝试使用 Java 7 运行 Jar 文件，而该文件设计为在 Java 8 上运行。安装 Java 8 并使用它运行 Jar 来修复错误。
