Reducing modpack warnings and errors

[doogle]

Hi everybody. I've had my custom mod pack up and running for a while now, but I was wondering how easy it would be to remove some, if not all, of the warnings and errors that pop up in the log as it loads.

Specifically errors and warnings such as these:

[WARNING] [ForgeModLoader] The coremod modname does not have a MCVersion annotation, it may cause issues with this version of Minecraft

[WARNING] [Minecraft-Client] ResourcePack: ignored non-lowercase namespace: %s in %s

[WARNING] [modname] Mod modname is missing the required element 'version' and a version.properties file could not be found. Falling back to metadata version [version number]

[WARNING] [modname] Mod modnameis missing a pack.mcmeta file, things may not work well

[sEVERE] [TConstruct] The language resource /assets/tinker/lang/pl_Pl.xml cannot be located on the classpath. This is a programming error.

[sEVERE] [Minecraft-Client] Using missing texture, unable to load: minecraft:textures/blocks/MISSING_ICON_TILE_3284_bookshelf.png

[sEVERE] [ForgeModLoader] TConstruct Compat: MFR is using a removed API and may crash the game.

[WARNING] [ForgeModLoader] Redundant call to BiomeDictionary.registerAllBiomes ignored

[iNFO] [sTDERR] [Mekanism] Error while adding recipe: mekanism.common.RecipeHandler

This one is confusing me as it seems to be telling me that a mod is overwriting it's own block with the same one!? Is this right?

[sTDOUT] CONFLICT @ 1289 item slot already occupied by net.minecraft.item.ItemBlock@4aad100f while adding org.millenaire.common.block.BlockDecorativeSlab$ItemDecorativeSlab@27f96f16

[fml.ItemTracker] The mod millenaire is overwriting existing item at 1545 (org.millenaire.common.block.BlockDecorativeSlab from millenaire) with org.millenaire.common.block.BlockDecorativeSlab$ItemDecorativeSlab

I think warnings like this one can only be removed by adding the mod mentioned? BackTools in this case?

[WARNING] [ForgeModLoader] BackTools missing - MFR BackTools Compat not loading

Then I get these beauties:

Any help in reducing or eliminating these errors would be greatly appreciated.

I see a few errors, but if the pack works, then there is no reason to worry.

let me tell you peace by peace:

for the 1st one, that is just something forge does if the mod info file for a mod is missing.

for the 2nd one, some mods aren't coded correctly, and over right them selfs.

for the 3rd one, it is not loading a part of a mod because you are missing a not needed mod.

for the 4th one.... I can see that it is a true error. it appears to be that powercrystals is errored. I would remove it or if the pack works, then ignore it.

Thanks, the pack is working even with the errors above. I have, I think, four of the java errors, but I've not noticed anything not working as yet.

I've just downloaded the latest versions of all the mods I use so will be upgrading my pack over the weekend, I'll see how many, if any, of the warnings etc. go with the updates

Well the update went well, and I added some more mods. Only getting a few errors now:

[sEVERE] [ForgeModLoader] tempus aspect missing.

I'm not sure what's happening with this one, I tried setting it to ID 700 but got the same error appearing, tho with 700 replacing the 31997.

[sEVERE] [ForgeModLoader] The entity ID 31997 for mod Jaffas-Power is not an unsigned byte and may not work

[sEVERE] [ForgeModLoader] The mod Jaffas-Power has attempted to register an entity ID 31997 which is already reserved. This could cause severe problems

Other than that it's just the normal textures missing and a new error about files not surviving a 1.7 upgrade.
