No, you're not. Unless you just lied and said you removed everything as this is a error caused by a mod you installed. And if you truly did remove everything that mod would not be there. As always always always post logs.

Run the jar from the console and give us the logs. Or manually install the libraries like it says in the eaq.

Give me directory listings.

Assume you're talking about a linuz system and ~ being your home dir, no, it needs to be in the minecraft/libs dir.

Always post with logs.

Interesting, i'm not able to reproduce in just forge. Does this happen on all servers, or just the MCPC server you showed. Also, try removing microblocks and trying. Note: MicroBlocks/Multipart is not part of Forge and if theya re the issue we cant support it.

Ya gunna lock this, I can just see this becoming a major issue/flamewar... no offense intended, just don't wanna deal with that crap.

Interesting, something is corrupting your class file. I would say it's a coremod that is broken. You can try running with -Dlegacy.debugClassLoading=true and pastebin-ing the log.

Well show us what DOES happen when you try and run it manually. And if you don't know how to get a md5 of a file, there's this wonderful invention called google -.- Fixing issues requires a little cooperation on your end.

Odd, try running the jar manually. Also, what is the md5 of the installer jar you have?

Rensik has been banned for being a cunt. The answer provided in the first place was perfectly fine. Don't get all huffy.

You have A LOT of mods in there that are erroring/derping up. Your best bet is to track down which of the coremods are in there are editing things that it shouldn't. I see a lot of errors trying to download the players skin, may be the cause.

Use the recomended build, or manually build the classpath, there was a slight bug with the gradle switch, post-gradle 1.6.4 builds are not advised to be used.

NEI needs CodeChickenCore not CodeChickenLib

Give us a console log of you running the installer.

By removing the mods, and trying again.

The ones specified in the json.

You have a mod installed thats trying to load client side code, and isnt compatible with the dedicated server you'll need to track that down/.

Use the recomended build.

Use the installer.

Gradle makes this obsolete, Also looking at it, this doesnt actually do jack shit besides display a random gui. And pro-tip GUI's wont work on headless servers such as build servers! Ya... No...

Its not a gui feature as it's part of the boot strap. Pass it to THE LAUNCHER. The jar or exe file you download from minecraft.net Ya, that.

Forge Version: 9.11.1 Minecraft Version: 1.6.4 Downloads: Changelog (Direct) Installer (Adfly) (Direct) Universal (Adfly) (Direct) Source (Adfly) (Direct) Javadoc (Adfly) (Direct) Alright ladies and gents. time again for another Recomended build of Forge! As I was kinda lazy in releasing these this one is kind of a duesy. This is the last supported build for 1.6.4 with ModLoader compatibility. We are hard at work on the update for 1.7. And with the death of ModLoader some things have changed. And we are trying to prepare for that. What does this mean for: The End User: If you want compatibillity with ModLoader, stick to builds 953 and below. Simple as that. We archive all older builds for this purpose we do not wish to lock you into any one thing. But please do not issue bug reports related to modloader of anything like that if you're using build 960+ This release is MAJOR changes under the hood in prep for the 1.7 update. There are some known issues with the new BlockBreak system and some older mods. Please use the 944 build if you run into those compatibility issues. The Forge Modders: If you are writing a Forge mod you should not be using ModLoader functionality for a long long time now. All Classes/methods have been marked Deprecated for a reason. This is your chance pre-1.7 major change to do a quick ModLoader purge. You can also look into the 960+ builds to see the new gradle build system. This is a major change to how things worked before, But I am confident with some time and community effort we can iron out all the kinks and get things working great for everyone. At the time of this writing, there are still some features that we are wanting to roll out, namely setupDecompWorkspace which will give you a read-only version of the Minecraft code. However, as ForgeGradle is seperate from Forge itself, we can retroactivly apply these new features to anyone who has migrated to the new build env. The road will be a little bumpy as we work out the kinks, so please be respectful and file issues on the apropriate Github, and for all inquaries with the new build system please direct them twards AbrarSyed. Minecraft Forge 9.11 Changelog: ============================================================================ Updated to Minecraft 1.6.4. New: Intaller now uses xz compressed downloads and a mirrior list which should spead up downloads and prevent server overloading.

New Zombie assistance summoning event, to allow mods to control this behavior more. Added new recipe sorting mechanic, it is recomended that both the client and server enable this feature in order for it to work correctly.

Add warning to item registration to prompt modders to register them with names in an attempt to make 1.6 worlds 1.7 compatible. New BlockBreakEvent, thanks Onibair and Blood, this change causes some issues with mods that use our fakePlyer system for client side only things, revert to build 944 if you must use those mods. Or wait for the mods to update. Bug Fix: Fixed NPE when loading single-player twice Fixed tweaker injection into classloader Fixed fluid rarity missing default Fixed typo in bounding box based ladder checks that caused potential infinite loops with entities in certian positions. Cross-modsystem compatibility fix with thanks to Mumfrey @ liteloader Made Vanilla hopper obey the IInventory contract, TileEntityHopper now takes into account IInventory.getInventoryStackLimit() when inserting items. Fixed placement of snow cover over metadata 6. Set densityDir in BlockFluidBase's constructor Fixed bug where some enchants could apply in invalid combinations at the enchanting table. Fixed install.sh not passing arguents to install.py Fixed issue that caused the per-world data storage to not be saved correctly. Delay sound system backend initalization to speed up startup and prevent race condition on some computers. Fixes no sounds issue on some machines. Fixed umpteen instances where 0 was referenced instead of air, should help mods that have plants/structure that grow. Fixed vanilla MC's decision to display session data in the console log.. This is bad Fixed NPE that caused the ChunkManager config to not load and save. Fixed issue where certian errors in the event bus were not logged correctly. Fixed issue in MC's logger code that caused resource pack warnings to not display properly. Fixed VersionCheckHandler documentation for the correct signature Fixed issue with wanter and lava localization

Use 953. 960+ is prep work for 1.7 and as such has ModLoader, All Public, and the likes removed {Note, I didn't notice this untill after but seem cpw wanted to do it in the 1.6.4 builds so whatever} 953 is the last officially supported build for 1.6.4.
