今天原本想开forge服务器
可是在安装forge步骤上面失败了
安装install版本会出现
Error: Invalid or corrupt jarfile inforge.jar
如果安装universal版本的话会出现
You will need to add them to your server before FML and Forge will run successfully.java.lang.ClassNotFoundException: net.minecraft.launchwrapper.Launch

网络问题你可以下载别人下载好的服务端或者说，在自己电脑上下载好后上传到服务器，有些服务器的服务商会禁止海外网络

你可以直接试试我这个打包好的

使用HMCL启动器可以随时手动更新Forge,自动安装

我去试试

我是ubuntu

建议直接下载catserver 服务端核心
这个支持插件和mod 而且不用瞎折腾辣么久

有地址吗
