Question

您好我正在尝试从Kotlin的REPL启动一个简单的JavaFx应用程序来显示图表。

启动应用程序的代码很简单，但我得到了

java.awt.HeadlessException

谷歌搜索，我找到了这个命令的引用，我跑了：

System.setProperty("java.awt.headless", "false")

真

但问题仍然存在，我使用Swing得到了同样的错误。如何从REPL中显示GUI对象？

感谢。

Intellij告诉我，目前这不可行。问题已经打开：https://youtrack.jetbrains.com/issue/KT-18181。

更新：此问题已针对1.1.4版修复。（这使得Intellij大约3天。他们不会在附近愚弄。）
