[HowTo] Install Minecraft Forge And My Mods

SanAndreasP · September 7, 2012

To install my mods, just drop the download into the /mods folder! I'm not responsible for an updated MinecraftForge install tutorial, it has now an easy-to-use installer, use it! I locked this now and will not be updated anymore!

This is a tutorial how to install Forge together with my mods.

This is NOT a place where you can post about forge issues! To do so, go to the Support and Bug Reports! Posts about problems with Forge will get ignored and deleted!

If you have a problem with installing a mod, go here -> http://www.minecraftforge.net/forum/index.php/topic,2829.0.html

If you encounter a crash, go to this thread! http://www.minecraftforge.net/forum/index.php/topic,2829.0.html

Note 1: This tutorial is updated regularly and can only be used with the actual version of Forge and Minecraft! This may work with older versions, but I'm not responsible for any damage you'll do to your minecraft setup if it's older!

Note 2: Minecraft Forge can NOT be installed TOGETHER with ModLoader / AudioMod! That means, if you've previously installed ModLoader and / or AudioMod, get a clean minecraft.jar and install Forge on that! Your ModLoader / AudioMod dependant mods should work together with FML.

The same goes for ModLoaderMP, except that MLMP dependant mods DON'T work with Forge! If you have a mod which depends on MLMP, either ask the mod author to switch to Forge or simply don't use this mod.

Note 3: Minecraft Forge is NOT ported for bukkit yet, so neither Forge nor any of my mods work with bukkit. Check MCPortCentral to get informed when a bukkit port for Forge is available. Please don't pester the devs of Forge about a port! They have already enough stuff to do.

[catbar]How to install Minecraft Forge[/catbar]

If you have Minecraft Forge already installed AND it's up-to-date, you can skip this part. If not, then follow these steps to install / update Forge!

Client:

Note: If you use any kind of launcher like MultiMC or MagicLauncher, use it and skip these steps (except the first one). Minecraft Forge is a JAR mod, so it goes into the "Jar Mods" section of your launcher! If it crashes after installing, look first at "Download and install needed libraries", then at the FAQ below. If the crash isn't solved then, then post the crash log here in the forums.

Download the recommented universal build (or the latest if the recommented doesn't work for you, but NOT the source!) from here: LINK
Open that archive with an archiver. I recommend 7zip.
Open your minecraft.jar in your .minecraft/bin directory with your chosen archiver (7zip)
Copy all files from the downloaded forge package into the minecraft.jar
Do not delete your META_INF in your minecraft.jar (anymore), Instead, go into the META_INF and delete only the files which begin with MOJANG! Leave the rest untouched. If there aren't such files, then leave it be. If it's crashing and you've downloaded the needed libraries, then delete the META-INF!
Close all open archiver windows and start your Minecraft client once. Forge needs to download some libraries and will set up the environment the first time. If you don't have an internet connection or it's really bad at the time (or it crashes / blackscreens at the start), go to the point "Download and install needed libraries".
After it has been set up by Forge, close your Minecraft. It is now ready for Forge / FML mods (ModLoader mods, too)!

Server

Download the recommented universal build (or the latest if the recommented doesn't work for you, but NOT the source!) from here: LINK
Open that archive with an archiver. I recommend 7zip.
Open your minecraft_server.jar with your chosen archiver (7zip)
Copy all files from the downloaded forge package into the minecraft_server.jar
Don't delete your META_INF! Keep it untouched.
Close all open archiver windows and start your Minecraft server once. Forge needs to download some libraries and will set up the environment the first time. If you don't have an internet connection or it's really bad at the time (or it crashes at the start), go to the point "Download and install needed libraries".
After it has been set up by Forge, close your Minecraft. It is now ready for Forge / FML mods (ModLoader mods, too)!

Download and install needed libraries

Close your client / server if not already done. Open the lib folder located either in your .minecraft directory (for client) or next to your minecraft_server.jar (for server)
Download this archive and extract the files in the archive into the previously opened lib folder: http://files.minecraftforge.net/fmllibs/fml_libs.zip
Close the lib folder and start your client / server again so that Forge can set up the environment

[catbar]How to install one of my mods[/catbar]

Note 1 (client): If you use any kind of launcher like MultiMC or MagicLauncher, use it and skip these steps (except the first one). All my mods are "Mods folder" mods, so it goes into the "Mods Folder" section of your launcher! If it crashes after installing, look at the FAQ below. If the crash isn't solved then, then post the crash log here in the forums

Note 2: Since 1.4.2, ALL my mods require my manager pack, which you can find here! Install it first like all my other mods (see below), then install my other mods. You need to install it only ONCE for all my mods!

All my (updated) mods are now packaged as a JAR file. Download the actual version of the mod you want to install.
Put the manager pack JAR (see note 2) into your mods folder located either in your .minecraft directory (for the client) or next to your minecraft_server.jar (for the server).
Put the mod JAR file into the same mods folder.
Start your client / server now. It should load the mod now and you can play with the mod.
To ensure the mod is loaded correctly: It shouldn't crash. If you still can't play with it, be sure you've installed Forge correctly and you've put the mod files in the right directory.

[catbar](way too) Frequently Asked Questions (FAQ)[/catbar]

My Minecraft blackscreens when I install forge

Be sure you have ONLY installed Minecraft Forge, NOT ModLoader nor ModLoaderMP! Get a clean jar with force update and install forge again on that.

My Minecraft blackscreens / crashes

Look at the ForgeModLoader-client-0.log or ForgeModLoader-server-0.log to find any kind of crash. If there's a crash not mentioned here in the FAQ and you don't know what's the problem, then post it here in the forums.

My Minecraft crashes with: java.lang.NoClassDefFoundError: com/google/common/collect/Multimap

One or more of the libraries needed by Forge are corrupt. Clean your lib folder and follow the steps in "Download and install needed libraries" above.

My Minecraft crashes with: java.lang.NoClassDefFoundError: com/google/common/io/LineProcessor

One or more of the libraries needed by Forge are corrupt. Clean your lib folder and follow the steps in "Download and install needed libraries" above.

My Minecraft crashes with: java.lang.ClassNotFoundException: net.minecraft.Launcher

Your launcher doesn't provide a class which is needed by Forge. Use an another launcher. I recommend the original Launcher (from Mojang), MultiMC (which I personally use) or MagicLauncher.

My Minecraft crashes with: cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: sanandreasp.mods.[something]

You installed one of my mods wrong (most likely you extracted the content from the jar into the mods folder / minecraft.jar / minecraft_server.jar). Clean your mods folder, get a clean minecraft.jar / minecraft.server.jar and reinstall everything by following the instructios above EXACTLY!

My Minecraft crashes with: cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: sanandreasp.mods.managers.[something]

You didn't install the manager pack! Download it and place it in your mods folder.

My Minecraft crashes with: java.lang.NoSuchMethodError: cpw.mods.fml.[something]

Your Forge isn't up to date! Update it!

SanAndreasP · September 8, 2012

interesting. its not in the mods directory...hmmmm

What do you mean?

Anyways i never delete meta inf everything works fine.

On which OS?

foreverblu · September 9, 2012

You but the .jar file in your .minecraft directory right?

EDIT: Nevermind...that was a mistake sry

malcolmg · September 9, 2012

I have tried to install forge 12 times now but it doesn't work. I have followed the instructions to the point, but the outcome is the same.

I come to your last step, after copying over the files into the minecraft.jar and deleted the INF folder and then starting minecraft.exe it starts downloading and installing the forge files. Then the screen turns black, I see the Mojang white screen with logo briefly then it turns black and stops there.

After that nothing happens. The minecraft client just stands with a black screen.

I have then deleted the bin folder, started minecraft up again to see that it works and repeated your process again. It ends up with the black screen inside the minecraft installer every time.

What am I doing wrong?

And by the way, who the fxxk is the creator of minecraft. It doesn't accept Mojang and it doesn't accept Marcus Persson???

malcolmg · September 9, 2012

More info, I had the modloader installed previously so I deleted the bin files (11 times).

If it helps, here is the log I get (ForgeModLoader-client-0.log)
