“无法为 javascript 创建 javax 脚本引擎”extjs

Question

在“默认”安装 extjs 后，我无法让它在任何 Java > 版本 14 上运行。

对于 Java 14，主要警告是：

[ERR] Warning: Nashorn engine is planned to be removed from a future JDK release

使用 Java 15ant构建失败：

有任何解决这个问题的方法吗？

Answer 1

我也遇到了同样的问题，但是是 Java 17。

我将 Java 更改为版本 8，并重新启动了所有终端，它解决了我的问题。
