我创建了一个新的代号一项目。在 src 文件夹中，我创建了一个代号一个表单：
显示项目层次结构的图像
当我右键单击表单并在 GUI 生成器中选择代号一>时，我收到以下消息：

GUI 生成器不会启动。
我正在使用Java 8，这是IntelliJ IDEA 2017.1.1的全新安装，安装了代号One插件，版本3.6.0。我在网上找不到一件事来帮助我解决这个问题。(我测试了卸载插件，而是安装了以前可用的版本 3.5.3，没有任何变化。
以下是有关我的环境的更多统计信息：
$ uname -a
Linux asus 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1+deb8u2 (2017-03-07) x86_64 GNU/Linux
$ cat /etc/debian_version
8.7
$ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
这似乎是此问题的一个案例。 此问题已修复，应该成为周五下一次插件更新的一部分。
