[Bug Starting Minecraft And FML]

Read the log

 

2013-01-22 22:17:01 [sEVERE] [ForgeModLoader] There were errors during initial FML setup. Some files failed to download or were otherwise corrupted. You will need to manually obtain the following files from these download links and ensure your lib directory is clean.

2013-01-22 22:17:01 [sEVERE] [ForgeModLoader] *** Download http://files.minecraftforge.net/fmllibs/argo-2.25.jar

2013-01-22 22:17:01 [sEVERE] [ForgeModLoader] *** Download http://files.minecraftforge.net/fmllibs/guava-12.0.1.jar

2013-01-22 22:17:01 [sEVERE] [ForgeModLoader] *** Download http://files.minecraftforge.net/fmllibs/asm-all-4.0.jar

2013-01-22 22:17:01 [sEVERE] [ForgeModLoader] *** Download http://files.minecraftforge.net/fmllibs/bcprov-jdk15on-147.jar

[forgemodloader .log 13 gigabytes]

And yes, you can delete it.

[Forge Server Issues]

Was the error you linked from a server? If so, post ForgeModLoader-Server.0.log instead

 

I'm just guessing based on what the first error was, if someone knows what is causing this and i'm way off base, please correct me.

[Forge Server Issues]

I see pipe mods in there that need BuildCraft, but not BuildCraft itself. I also see the PluginsForForestry mentioning a "denLib", but I don't see that either.

[Divine RPG crash]

Upgrade Forge to 504

[Forge Server Issues]

Sounds like at least one of your mods is missing a dependency.

 

Post your ForgeModLoader-Client.0.log from your .minecraft directory so we can see exactly what's going on

[Crash report: Forge-snapshot 7.7.0.500, crash with 13w02b]

He (or someone else) probably pulled the source from the 1.5 branch and compiled it.

[verify error in 1.4.7]

The problem was that mod is for MC 1.2.5. The 1.4.7 version can be found here: http://www.minecraftforum.net/topic/1613220-146-steampunk-airships-forge/

[new forge and minecraft fatal error/black screen]

You're running an old version of CodeChickenCore

 

Either remove it from your coremods folder, or upgrade to the latest (0.7.0.2)

[Sorry if this a duplicate post...the first got lost: Black screen after upgrade]

Only delete the original one inside the vanilla minecraft.jar

 

We need you to post the contents of your ForgeModLoader-Client.0.log files (located in the .minecraft directory) so we can see what the error is

[Forge Mod Loader has found a problem with your minecraft installation]

That means you're running a version of Forge that is too old for one of your mods. Update your Forge to the version it says, or newer.

[Crash Report~ Help Please!]

Looks like you have ClaySoldiers installed twice, somehow.

[Can't install Forge on Vanilla server]

And you're putting the forge .jar in the bin folder with the 1.4.7 minecraft_server.jar?

[Server/Client sources not found on recompile 1.4.5]

Your output has no errors in it.

 

As of 1.3.2 there are no separate server sources so that warning message during recompile, you can just ignore.

[Installed forge with portal mod]

It's only a Pre-release right now, but it's minor changes so you can use 1.4.7 client on 1.4.6 server and most mods work between the versions.

[[SOLVED] "unable to locate sign" error]

Use Build 6.5.0.489 from http://files.minecraftforge.net/

[Can't install Forge on Vanilla server]

You don't need to install it at all, actually.

 

Do what you did, brethir. Just put the forge .zip in the bin folder and rename it to .jar, then run it instead of the minecraft_server.jar

[Stuck at "Done loading" after install]

2013-01-01 01:46:40 [sEVERE] [ForgeModLoader] This version of FML is built for Minecraft 1.4.7, we have detected Minecraft 1.4.6 in your minecraft jar file

[Recipes error can't find the problem]

Pastebin the whole class so we can see the context.

 

Offhand, it's probably because you're using an object before you instantiate it.

[Newbie asking, Black Screen]

People say "Read the EAQ" for a reason. The Excessively Asked Questions (EAQ) tells you what to do in the most common instances of errors.

 

For example, the first line in the EAQ reads

 

java.lang.NoClassDefFoundException: net.minecraft.Launcher; Use a proper launcher. Mojang's/MultiMC/Magic Launcher are all known to work. Don't use sk89q's.

 

If you look at your logs that you posted above, it says

 

2012-12-13 22:03:45 [iNFO] [sTDERR] Exception in thread "Thread-11" java.lang.RuntimeException: cpw.mods.fml.relauncher.ReflectionHelper$UnableToFindClassException: java.lang.ClassNotFoundException: net.minecraft.Launcher

 

See how the EAQ can be helpful now?

[Forge for minecraft 1.1]

http://files.minecraftforge.net/

 

Scroll down to where it says "MC 1.1"

[Registry Error]

Move

GameRegistry.registerBlock(BlockBong);
        LanguageRegistry.addName(BlockBong, "Bong");
        GameRegistry.registerBlock(ZCrop);
        LanguageRegistry.addName(ZCrop, "Z");

 

to after

 

BlockBong=(new BlockBong(252, 1)).setBlockName("BlockBong").setHardness(2F).setResistance(5F);

 

You're using BlockBong before it has a value, which you cannot do.

[Bug can you please help.]

2012-12-02 09:45:43 [sEVERE] [ForgeModLoader] The mod Thaumcraft (Thaumcraft) requires mod versions [Forge@[6.4.1.407,)] to be available

 

Anything 407 or above

[error when starting up minecraft. please help]

Thaumcraft needs a least Forge 6.4.1.407, you're running 397

 

You can get the right build from here: http://files.minecraftforge.net/

 

There also seems to be a rendering error, but it might be a false error from running the wrong forge version, I don't know.

 

If there is still an error after you update, post the new log.

[Entity is already tracked! [temporarly solved]]

You didn't remove all your mods, you still have NEI and CCC in your coremods folder.
