Coremod's META-INF

[jumika]

Hi!

 

I'm trying to follow the Using Access Transformers tutorial on the wiki. But once i got the jar file copied to the coremods folder, the console says:

 

[sEVERE] [ForgeModLoader] The coremod xy.jar does not contain a valid jar manifest- it will be ignored

 

I've double checked the content of /META-INF/MANIFEST.MF and according to the tutorial it is correct.

 

Manifest-Version: 1.0
FMLCorePlugin: jumika.minecraft.vitalchanges.LoadingPluginVitalChanges

 

I have a class named LoadingPluginVitalChanges that implements IFMLLoadingPlugin in the package jumika.minecraft.vitalchanges.

I have that problem sometimes, no clue why, CPW might know, but the way I use to get around it is to get one of

CB's mods (NEI or something) and copy it's META-INF/MANIFEST.MF to mine, and just change the name of the FMLCorePlugin bit.

Thank you!

It's working now. I don't have any ideas why it's happening. Maybe i'll try to make the META-INF on a linux machine, than report back.

I figured this out, for what it's worth... posting here because this topic is the top Google result for "minecraft forge valid manifest".

 

There must be an extra line in the file, completely blank. So it should look something like this: (line numbers next to the actual lines)

 

1 Manifest-Version: 1.0

2 FMLCorePlugin: your.plugin.name.Here

3

 

Note the extra blank line. Actual file:

 

Manifest-Version: 1.0
FMLCorePlugin: your.plugin.name.Here
