【问题描述】：
我创建了一个新的 Codename One 项目。在 src 文件夹中，我创建了一个 Codename One Form：
image showing project hierarchy
当我右键单击表单并选择 Codename One > GUI Builder 我收到以下消息：

GUI Builder 没有启动。
我使用的是 Java 8，它是 IntelliJ IDEA 2017.1.1 的全新安装，安装了 Codename One 插件，版本 3.6.0。而且我在网上找不到任何东西来帮助我解决这个问题。 （我测试了卸载插件并安装以前可用的版本 3.5.3，没有任何改变。）
以下是关于我的环境的更多统计信息：
$ uname -a
