java - 为什么我的 1.12 中的 mcp 反编译器不起作用？

Question

我的 mcp 反编译器有问题。

• 我已经安装了最新版本的 JDK (Java 8)
• 我已逐步按照教程进行操作（https://minecraft.fandom.com/fr/wiki/Aide_au_d%C3%A9veloppement/Installer_le_Mod_Coder_Pack）
• 我没有修改任何代码

这是我的控制台的输出：

== MCP 9.40 (data: 9.40, client: 1.12, server: 1.12) ==
"scalac" is not found on the PATH.  Scala files will not be recompiled
# found ff, ff patches, srgs, name csvs, doc csvs, param csvs, astyle, astyle config, rg, ss
