Trouble with custom modpack

[Xenans]

Hi guys, I've recently been trying to create a custom modpack for me and my friends to play on. It includes my favourite mods, but as I am a newcomer to creating modpacks, I simply can't get it to work. I'd like some advice to help me to get it to start. I know i did something wrong, but I'm not certain what. With the way things are right now, I have a jar file in my bin folder named modpack.jar, and a bunch of mods/coremods in my mods folder, but whenever i press play, it starts to launch it, but it crashes and gives me this error message

Before this, I tried messing around but I didn't know much so I had mods in my coremods folder even though I was in 1.6.4. At that time i only had 4 files, the bin folder, the config folder, the coremods folder, and the mods folder. I created the folders, and when i launched it, it launched vanilla 1.6.4 minecraft.

 

I would have posted this crash report at https://github.com/TechnicPack/TechnicLauncher/issues, but I know there are more underlying issues with ID conflicts and me not configuring things properly so I thought I would post it here so I could get a more detailed and more helpful fix for the modpack.

I hope you guys can help me sort this out, it's given me so much trouble and i just can't seem to figure it out!

 

Edit:I realize that the vanilla tag isn't very fitting, but my modpack did start up as vanilla for a bit, so I added it anyways

• You have zipped up your entire client folder as your modpack archive. Your modpack archive should ONLY contain the folders "bin", "config" and "mods". The "bin" folder should ONLY contain the file "modpack.jar".
• Your modpack.jar file seems to be the correct version of Forge, but it is an odd size. Unless you have very specific, uncommon reasons for doing so the modpack.jar file is simply the Forge universal binary JAR file renamed to "modpack.jar". I would recommend fixing this.
• You have OpenBlocks mod but not the required dependency mod OpenModsLib.
• You have the GeoStrata mod but not the required dependency mod DragonAPI.
• You have the Mariculture mod but not the required dependency mod Enchiridion.
• Your BloodMagic mod is so out of date that it is conflicting with other mods.
• You have the FlatSigns mod for Forge/MC 1.7.10. You need to get the version for 1.6.2 (which works in 1.6.4).
• The GeoStrata mod has a fatal item ID conflict in the default configs. You can safely change the 10000-10006 to 11000-11006.
• You have the wrong ExtraCells mods. You need: ExtraCells-1.6.9e.jar (not the deobfuscated version)
• Your IndustrialCraft mod is out of date. If you intend to include IndustrialCraft for 1.6.4 in your pack I would recommend reading through this:
• There is a block ID conflict between GeoStrata and Mariculture for ID #800. Change GeoStrata's SmoothRock ID to 839.

After figuring out all the problems a few things are clear:

• You are not testing the pack as you go. On cannot simply drop 75 mods into the pack and expect it to work properly. The pack must be built methodically with mods being added singly or in logical groups.
• It is clear that you are either not getting your mods from the author's preferred distribution channels or are not following their instructions for installation. You would probably benefit from reading through this:

Come back here if you are still having troubles.

Thanks so much for your help! I'm going to create a new one and repeat everything since I obviously messed up, but thanks for setting me on the right direction. I had no idea what to do.

I maintain a modpack called BareBonesPack which exists for the purpose of debugging modpacks or building new ones. You might have an easier time using it:
