# 附录Ⅲ：FAQ

### 为什么我配置好的forge模组开发环境能run Client但是run Server闪退？

我觉得很有可能是你没有同意协议，如果最后几行输出内有“You need to agree to the EULA”这样的字样那就实锤了。在`你的forge目录/eclipse/eula.txt`下把eula=false改成eula=true就成了。(实这个问题超出此教程范围，但是因为是很多人犯的错误我就说一下，下同)

### run Client关闭游戏出现**"Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release"**

虽然在大多数IDE中这个所谓的报错是以红色出现的，所以很多人会把它认为成一个bug，并且寻求帮助。但是这并不是一个报错，如果你读得懂它，你会发现其实就是Java不推荐使用某个东西。如果你还知道CMS回收，并且知道Java8不推荐使用它，那你应该就知道这个所谓的报错输出的原因了。

### 为什么我把客户端的mods文件夹直接放进服务端的mods会报错？是服务端不兼容吗？

当然服务端不兼容的可能性是存在的，但是大部分情况下是用户把客户端mod带进服务端以至于报错。
