![Mqtt-spy 无法打开](https://linux22.com/image/1089286/Mqtt-spy%20%E6%97%A0%E6%B3%95%E6%89%93%E5%BC%80.png)
我正在尝试安装 mqtt-spy,但它就是打不开。我已经安装了 java8 和 java9,当我使用命令时:
java -jar mqtt-spy-0.5.4-jar-with-dependencies.jar
这是我得到的输出:

我也有同样的问题。当我运行这个时,用户界面从未显示出来

答案2
我尝试了mqtt-spy-0.5.4-jar-with-dependencies.jar
和mqtt-spy-1.0.0.jar
。
在 Ubuntu 16.04 LTS 上安装 OpenJDK 1.8.0_131 软件包后,它们可以正常启动openjfx
。建议在维基页面。
