I want to log in in the Eclipse-Minecraft (Modding state) with my normal minecraft account. With the 1.5.2 version it worked fine:

Run Configuration -> Arguments
" <MC-Loginname> <Password> "

Now, in 1.6.2 this doesn't work anymore. The default arguments are:

--version 1.6 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker

What can I do to log in with my own account?

 

Thanks in advance!

The only way I've been able to get 1.6.2 to recognize a user is to pass both the --username and --session arguments in, directly copying the sessionID from the new Minecraft launcher (under the "Session ID is token:******************:************" line).  I'm not sure how long that token remains valid, however, and they will become invalid if you open a new Minecraft instance from the launcher.

Thanks! It worked

 

Does this still work?

Launcher 1.2.7 doesn't appear to show the session id??

I use just the '--username <insertyourusername>' argument (in Run->Run Configurations->Arguments) and that is working fine for me (MC 1.6.4).

thanks
