What launch arguments are you using in your run configurations?

 

like "--version 1.6 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker" ?

--version 1.6 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker --username <Your_MC_Username> --session <Your_Session_ID>

it's "--version 1.6 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker --username <Your_MC_Username> --session <Your_Session_ID>"

 

and i tried working path for mcp/jars mcp/src/minecraft out/production/

here's my current (working) setup in intellij idea:

main class:    net.minecraft.launchwrapper.Launch
vm params:     -Djava.library.path=versions\1.6.4\1.6.4-natives -Xmx512m
program args:  --tweakClass cpw.mods.fml.common.launcher.FMLTweaker --username <name>
wokring dir:   <project-dir>\jars

My content root is

mcp

dir. My output dir is the same as in eclipse -

eclipse/Minecraft/bin

. Also I copied

forge_at.cfg, deobfuscation_data-1.6.4.lzma, fml_at.cfg, fml_marker.cfg, fmlversion.properties, mcpmod.info

to the bin dir. It might not be necessary but it works .

 

PS: I'm not on mac, but the correct setup could be similar.

If you don't want to copy a bunch of files by hand, there is another solution. The reason the .cfg and other files don't get copied is because Intellij doesn't think they are resource files. To solve this, you can change your Intellij settings as follows:

 

1. Go to Settings/Preferences -> Compiler -> Resource patterns

2. Add <;?*.cfg;?*.info;?*.lzma> (without the chevrons, obviously) to the end of the list of resource files.
