Minecraft normal client?

On my favorite server there's always an event every day at 7pm, so I thought I'm modifying Minecraft so no players are rendered anymore.

But before I came to that, I wanted to test whether it works normally without anything. So I installed MCP for 1.8.8, let it decompile and let it run. Everything OK so far. However, when I exported the client from the Eclipse workspace, created a folder for it and added a JSON, the profile will be displayed, but I can also start it, but I can't join any server. (in eclipse I could run on server joinen (so only cracked)) What could be the reason?

JSON:

Version: MCP 1.8.8

(only on the edge I still have Optifine SRC inserted into the client, is that a problem?)

Hope for help!

Are there crash / errorlogs?

Yes, I'll just drop in for a moment

It does not seem to find Netty, hm

What can you do there? : /

Download the io.netty source and drag it to the src folder ^^

Thank you very much could you please send me a download link please?

https://dl.bintray.com/netty/downloads/netty-4.1.39.Final.tar.bz2

That should be it

If it should not be, please just search yourself. You can add that as a lib. But I have to go to school now, bye!

Ok, thanks, if anything else, could I contact you?

I'll try it out and then I'll write you obs sparked.
