Hello Everyone,

 

Sorry if this is a crummy question, I have not found any answers online.

 

I have just started minecraft modding and after doing a bunch of different tutorials and reading a ton of different resources. I had a pretty large mod going.

Whenever I'd run my mod inside of the Eclipse IDE it would be fine! I decided to build my mod and test it out in FML on an actual minecraft client as a .jar. To my surprise I ran into countless errors with my mod and instant crashes upon loading Minecraft.

 

Is is common for this to happen? I have been trying to debug and chase down the errors in minecrafts crash report, but the only thing I've been able to do successfully is comment out almost everything.

 

If anyone wants to snoop around, the link to my github is here https://github.com/jibbodahibbo/MC_Mod_Files/tree/master/src/main

 

Edit: To clarify I have ran a gradlew build inside of a batch file inside the folder. This is how I am getting errors trying to run my Mod In FML.

 

Thanks,

Jibbo

No, don't do "export jar".

When it comes to forge, you have to use 'gradlew build'.

Abastro, Thanks for responding. I did both (primarily gradlew build) and neither work.

Is this what you are Looking for?

Follow these instructions!

1. Open CMD in your mod folder

2. Run gradlew build

3. Go to YourModFolder\build\lib

4. Take out modid-1.0 rename it to whatever

5. Thats all

Thanks Many,

 

I tried running it through the cmd and the jar did not work.

It seems that your mod is not getting obfuscated..

Please tell us what you did, for there would be some mistake.

I'll walk through it as best as I can. Thank you for the help!

 

-I set up my workspace for my mod using mostly mr.crayfish's tutorials online.https://www.youtube.com/watch?v=VhOSL7rGb10

-set up the jdk and the environment variable path.

-I created 3 folders. 1 for my mod files, 1 to hold eclipse. and another for the minecraft game client.

-ran gradlew eclipse, gradlew setupDecompWorkspace

-created some mods using 1.8 and 1.7 techniques

-All the mods worked fine in eclipse, although I did get a weird issue with my custom block (DigiBlock) when I debugged.

-I decided that I wanted to finally build the .jar and did so running gradlew build

-I installed FML again inside of a different minecraft client that is located in my desktop.

-Placed the .jar inside the mod folder inside of AppData\Roaming\.minecraft\mods

-Ran Minecraft client, chose the FML 1.8 as my profile

-Errors.

 

-I tested the Forge Mod Loader with a "blank" mod which didn't include any initializing or registering of any items, blocks, creative tab, etc. It worked, and my mod showed up in the Mods list.

So your jar is from \build\lib?

If then, try gradlew clean, and gradlew setupDecompWorkspace eclipse build.

No success, still getting the same errors. :\ , I have other workspaces set up, could these be a problem?

What do you mean by "other workspaces set up"? If it is just a separated workspace, it must not affect this workspace.

I wouldn't suspect they are effecting anything. I'm going to try re installing minecraft and see if that works.

Do you use same version of Forge???

Elix,

The version inside my mod folder according to the change log is this.

forge-1.8-11.14.0.1290-1.8  Is there a better way to check which version of FML is installed?

 

 

I tried using a few versions of FML 1.8 to no avail.

 

Edit: forgeSrc-1.8-11.14.0.1290-1.8.jar is what shows up in eclipse inside referenced libraries. My JRE is jre1.8.0_25

 

Edit2: this is what shows up when i run it in eclipse.  http://imgur.com/Xqo99oH

 

 

Edit3: Changed my Forge and FML versions on my client. It works now. Thank you so much for all the advice you guys rock! http://imgur.com/ISZyJcB
