更新插件到 java16 + nashorn 15.2的时候
遇到了一些nashorn奇怪的问题
先上代码
https://gitee.com/Soldier233/Vip ... /ScriptManager.java
运行时 控制台debug信息和报错如下

对应的js文件如下
  1. var bukkit = Java.type("org.bukkit.Bukkit");
  2. //获取Bukkit
  3. var Vector = Java.type("org.bukkit.util.Vector");
  4. //获取Vector向量

  6. var activate = function (player) {
  7.     //此时传入的player参数为字符串
  8.     helper.sendMessage("&6公告 &7>>> &f玩家 &a" +player+" &f购买了临时飞行权限，大家快去膜拜一下氪金大佬!");

  10. };
复制代码
这个咋就获取不到名叫activate的函数了呢？
有没有dalao知道的？

你试着eval里面直接带上调用函数的代码
而不是invokeFunction试试看？

测试了一下
发现 不带bindings或者context
直接eval是可以用的
但是CompiledScript不能用

带了bindings或context
一个都用不了

但是频繁eval又会造成卡顿。。
所以还是得想办法解决不能预编译的问题
