Hello guys. I've meet an issue when working on a custom launcher for my private server. I know this is not a Java forum here but I think only you would be able to help me. I use this to know how the minecraft launcher starts a forge profile : 

ps -aux | grep forge

This is the output I got :

This is especially interesting : 

[21:58:06] [main/INFO] [STDERR]: [java.lang.Throwable:printStackTrace:634]: Caused by: java.lang.ClassNotFoundException: net.minecraftforge.fml.common.FMLLog

So my question is : what have I done wrong ?

If you think you can be useful, I'll be glad to try what you advise me. Thanks in advance.

 

If you are interested in : this is the link of the project's branch I'm currently working on.
