less（版本 2.5.3）与 Rhino（或 Nashorn）
less (ver. 2.5.3) vs Rhino(or Nashorn)
情况是 - 我在 less GitHub 上有这个问题
题目是"Rhino doesn't work with less older 2.X.X"，而且我还有official less site的那个手册，上面说编译很简单！您只需要从命令行输入 运行 命令即可。但这对我不起作用。
所以我的问题很简单 - 是否有任何关于如何使用 Rhino（或者 Nashorn）编译 less 2.5.3 版本（或接近它）的主题，也许有一些技巧或第一眼看不清楚的东西。或者开发人员明确 "NO YOU CAN'T DO IT!" 的主题。
我认为答案是不，你做不到（现在）。
GitHub 问题跟踪系统中存在未解决的问题：Rhino Support in 2.x。
我还尝试使用 Less 2.5.1 和 Rhino 编译 less 源代码。不幸的是它不起作用：
