Minecraft forge error when launching

[mrben829]

I just installed the latest version of minecraft forge for minecraft 1.6.1, and here's the error im getting.

 

Client> Exception in thread "main" joptsimple.MultipleArgumentsForOptionException: Found multiple arguments for option ['version'], but you asked for only one

Client> at joptsimple.OptionSet.valueOf(OptionSet.java:178)

Client> at net.minecraft.launchwrapper.Launch.launch(Launch.java:41)

Client> at net.minecraft.launchwrapper.Launch.main(Launch.java:18)

 

I don't understand how it wants more than 1 version arguments because in the launch code there are 2 version parameters and they are:

--version Forge8.9.0.761

--version last

 

Does anyone know how to fix this?

'launch code'?

There should only be one argument.

[mrben829]

When I launch vanilla minecraft or forge, there are always 2 version arguments. Vanilla minecraft will accept the 2 version arguments, but forge will not accept it.

 

Until this bug is fixed, I will have to launch forge with minecraft via cmd.

Finally fixed it by removing the second version parameter from the json file. Forge is working fine now.
