That's not the point, it's specifically in the rules to not post jars, or at least it was last time I checked.
Minecraft and all associated assets are property of Mojang. Redistribution of Mojang owned property (for example Minecraft.jar) is not allowed, all posts must remain inline with the Minecraft Terms Of Service. Linking to Mojang hosted files is acceptable, eg: assets.minecraft.net.
